Evolution of the original HM5005/HM5006 has led to the new HM5010/
HM5011 Spectrum Analyzer/Tracking Generator which now extends
operation over 1 GHz (frequency range 0.15 to 1050 MHz). Both fine and
coarse center frequency controls, combined with a scanwidth selector
provide simple frequency domain measurements from 100 kHz/div. to 100
MHz/Div.. Both models include a 4½digit numeric LED readout that can
selectively display either the center or marker frequency. The HM5011
includes a tracking generator.
The HM5010/5011 offer the same operation modes as the HM5005/5006.
The instruments are suitable for pre-compliance testing during development
prior to third party testing. A near-field sniffer probe set, HZ530, can be used
to locate cable and PC board emission "hot spots" and evaluate EMC problems
at the breadboard and prototype level. The combination of HM5010 / 5011 with
the HZ530 is an excellent solution for RF leakage/radiation detection, CATV/
MATV system troubleshooting, cellular telephone/pocket pager test and EMC
diagnostics. There is an optional measurement output for a PC which makes
documentation of results easy and affordable with the HO500 Interface.

HO500 Computer Interface for HAMEG Spectrum Analyzer
This HO500 computer interface offers the facility to transfer a calibrated frequency
spectrum from any HAMEG spectrum analyzer to a PC. The HO500 interface is a
8 bit ISA BUS card installed in the PC, which transfers data via an interface cable.
The software supplied allows a hard copy print out (including parameters) of the
frequency spectrum, in Windows Format. Signal aquisition occurs 2 to 3 times per
second.
The picture consists of 10 bit vertical by approx 3600 point horizontal display. The PC
monitor display is in SVGA Format with 800 x 600 pixels. For comparison
measurements, a previosly stored reference curve can be recalled. The software
supplied works under Windows 3.1, 3.11 and WIN95. A simple XY analog output is
required to connect the HO500 to the spectrum analyzer.

The High-Impedance Probe
The high-impedance probe (Hi-Z) permits
the determination of the radio frequency
interference (RFI) on individual contacts or
printed circuit traces. It is a direct-contact
probe. The probe is of very high impedance
(near the insulation resistance of the printed
circuit material) and is loading the test point
with only 2 pF (80Ω at 1 GHz). Thereby one
can measure directly in a circuit without
significantly influencing the relationships in
the circuit with the probe.
One can, for example, measure the quantitative effectiveness of filters or other
blocking measures. Individual pins of ICs can
be identified as RFI sources. On printed
circuit boards, individual problem tracks can
be identified. With this Hi-Z probe individual
test points of a circuit can be connected to
the 50Ω impedance of a spectrum analyzer.
The E-Field Monopole Probe
The E-field monopole probe has the
highest sensitivity of the three probes. It is
sensitive enough to be used as an antenna
for radio or TV reception. With this probe the
entire radiation from a circuit or an equipment
can be measured. It is used, to determine the
effectiveness of shielding measures. With
this probe, the entire effectiveness of filters
can be measured by measuring the RFI which
is conducted along cables that leave the equipment and may influence the total radiation.
In addition, the E-field probe may be used
to perform relative measurements for certification tests. This makes it possible to apply
remedial suppresion measures so that any requalification results will be positive. In addition,
pre-testing for certification tests may be performed so that no surprises are encountered
during the certification tests.
SCALE = 10dB/DIV.
The H-Field Near-Field Probe
the connected measurement system which
is proportional to the magnetic radio
frequency (RF) field strength existing at the
probe location. With this probe, circuit RF
sources may be localized in close proximity
of each other. The H-field will decrease as
the cube of the distance from the source. A
doubling of the distance will reduce the Hfield by a factor of eight (H = 1/d³); where d
is the distance.
In the actual use of the H-field sensor one
observes therefore a rapid increase of the
probe’s output voltage as the interference
source is approached. While investigating a
circuit board, the sources are immediately
obvious. It is easily noticed which component
(i.e. IC) causes interference and which does
not. In addition, by use of a spectrum analyzer,
the maximum amplitude as a function of
frequency is easily identified. Therefore, one
can eliminate early in the development components which are not suitable for EMC
purposes. The effectiveness of countermeasures can be judged easily. One can investigate shields for "leaking" areas and cables
or wires for conducted interference.
SCALE = 10dB/DIV.
The HZ530 is the ideal toolkit for the
investigation of RF electromagnetic
fields. It is indispensable for EMI precompliance testing during product
development, prior to third party testing.
The set includes 3 hand-held probes
with a built-in pre-amplifier covering the
frequency range from 100kHz to over 1000
MHz.
The probes - one magnetic field probe,
one electric field probe, and one high
impedance probe - are all matched to the
50Ω inputs of spectrum analyzers or RFreceivers. The power can be supplied
either from batteries, Ni-Cads or through a
power cord directly connected to an
HM5010/HM5011 series spectrum
analyzer.
Signal feed is via a 1.5m BNC-cable.
When used in conjuction with a spectrum
analyzer or a measuring receiver, the
probes can be used to locate and qualify
EMI sources, as well as evaluate EMC
problems at the breadboard and
prototype level. They enable the user to
evaluate radiated fields and perform shield
effectiveness comparisons. Mechanical
screening performance and immunity tests
on cables and components are easily
performed.

Alignment Procedure for HM5010/HM 5011
Attention! The opening of covers or removal of parts is likely to expose live parts and accessible terminals
which can be dangerous to life. Maintenance, service and alignment should be carried out by qualified
personnel only, which is acquainted with the danger involved.
When aligning the HM5010/5011 it is assumed that all sub-assemblies of the instrument are completely pretested and
working correctly. The tuner, IF-unit, and tracking generator should be pre-aligned. When aligning a HM5010, a separate
tracking generator unit must be available and connected to the HM5010 for some specific adjustments.
Prior to the alignment procedure, the instrument must warm up for 60 minutes.
All adjustments are carried out by means of a plastic screw driver or a ceramic adjustment tool.
The alignment is divided into the following steps:
A Checking of supply voltages
D Linearity alignment
B Alignment of the tuner
E Tracking generator alignment
C Alignment of the IF-unit
F Check of overall adjustment

Final Adjustment - Tuner
The tuner is already aligned by the factory. When changing the 1st mixer, it might be necessary to realign cavity filter:
Set signal to 500MHz -27dBm to input, center frequency to 500MHz, Scanwidth to 0.5MHz, turn all three M3 screws
to max. amplitude. In case curve is not uniform, coils L1, L2, and L3 can be adjusted to maximum uniformity (fig. 22)
by slightly bending them.
In case signal in frequency range is shacky, 2nd local oscillator might not be snapped in correctly. The correct snapin of the PLL is visible via the lock detect LED (D2), which has to be lit constantly without flickering if PLL is snappedin correctly.
The oscillator signal has to be fixed (crystal dependent) at 1.32GHz, it may not drift.
The PLL is snapped-in when the tuning voltage VT (measure at PAD1) is between 0.5 and 4.5V. The alignment will
bring the tuning voltage to the center of the tuning range. VT of the 2nd LO has to be between 2V and 2.5V. Constantly
check tuning voltage while aligning tuner.
Alignment is necessary in two cases: VT<2.0V and VT>2.5V.
• Case 1 VT<2.0V
Correction:
a ) Solder all adjustment areas to connect trace from C1 to C2.
b ) Remove excess solder at center conductor of resonator pad.
• Case 2 VT>2.5V
Correction:
a ) Adjustment areas may not be soldered to connect trace from C1 to C2.
b ) Add solder to resonator pad.

middle of the screen (–30 dB).
This alignment has to be performed repeatedly in order to optimize settings.
Fine Alignment: Connect BNC-T-connector again as in the beginning of the IF alignment. Set attenuator of tracking
generator module to –20dB, scanwidth to 0.5 MHz/div. If necessary, re-adjust center frequency

IF Gain - Adjustment of different Bandwidths
Set scanwidth to 0.2MHz/div. Switch bandwidth repeatedly between 400kHz and 20kHz. The distance between the
output voltage (line) of the tracking generator and tge 400MHz amplitude may not vary. If the amplitude values do
not match exactly, adjust by means of R-trimmer VR2 (PIC5)
(PIC5).
Linearity of IF-Amplifier Gain
The linearity of the IF-amplifier gain has to be checked through the entire display range. Apply a 400MHz (-27dBm)
signal directly to the input of the HM5010/5011. Adjust scanwidth to 5MHz/div, release attenuator switched (0 dB),
select filter bandwidth of 400kHz. The spectral line should reach the upper screen edge. Use attenuators to reduce
signal in 10db steps, whereby each individual attenuation step has to reduce the level by 10dB ±1dB. In case deviation
is as follows:
- A the drop of the individual attenuation steps is larger than 10dB ± 1dB, or
- B the drop of the individual attenuation steps is smaller than 10dB ±1dB, the linearity of the attenuators has to be
adjusted as follows:
Set attenuator to -40dB. Adjust spectral line exactly to -40dB (center line) via VR1, VR3, VR4. Then set attenuators
back to 0dB und adjust spectral line by means of trimpots VR802A and VR801 (XY board) to zero point and base
line to bottom graticule line. This procedure has to be repeated until the settings at -40dB and 0dB are correct.

Linearity of Frequency Display
Settings for HM5010/5011:
Center frequency at 500MHz; all attenuator switches released; filter bandwidth

Measurement Setup: Apply signal of 500MHz –27dBm to input of HM 5010/5011.
Check:
Check:

Basic setting: The HM5010/5011 has to be adjusted that the noise level touches the bottom graticule
line. The spectral line of 500MHz -27dBm reaches the top graticule line and is situated in the center of
the screen. Adjust 500MHz spectral line exactly to screen center via X-pos knob (on front of the unit).
Upper frequency limit: Check if frequency of minimum 1050 can be set as center frequency.

5.1 The 2nd LO oscillates at a frequency of 1.35 GHz. The level at the mixer input IC3 Pin2 is -17dBm. Oscillation
of the 2nd LO can also be measured with the H or E-Field Probe (HZ530).
5.2 Lock-Detect LED (D4) will confirm the correct PLL lock when lighting up without flickering or going out.
The oscillator signal has to remain fixed crystal dependent) at 1.35GHz and may not drift. PLL is locked if tuning
voltage VT (measure at PAD2) is between 0.5 and 4.5V. Align tuning voltage to medium tuning range. VT of
fixed LO should be between 2 and 2.5V. The tuning volage has to be check constantly during alignment.

6.1
To check 2nd LO-level, cap C20 (22pF) has to be removed and 50Ohm Coax-cable has to be connected to 13dB attenuator of output. Connect other end of coax cable with adequate test analyzer.
Adjust test analyzer to 1.35 GHz center frequency; the LO-level to be measured has to be -17dBm (±1 dB)
(consider attenuation of cable).
If cap is not removed and coax cable is connected parallel to mixer to the VCO-branch, a level of approx. -24
dBm (±1dB) should be measured due to decreased load resistance.
6.2
6.3
7.
Check of VCO
7.1
7.2
7.3
Adjust HM5011 to Zero Scan, center frequency to 500MHz.
Remove Cap C14 (22pF), connect one side to attenuator output, other side stand up in the air.
Connect Cap side sticking up in the air to center conductor of 50 Ohm cable. Solder shielding of cable directly
next to Cap to ground. Connect other end of Cap to Analyzer input (i.e. Advantest R3361A). Start 1.35GHz Stop 2.35GHz reference level: 0dBm.
VCO signal which can be observed on the test analyzer has to shift according to center frequency (tuning
voltage). Tuning range has to be at least from 1350 to 2350 Mhz. continuously and without interruption. It
should not go under absolute level of +7dBm (coax cable of 1 mtr. has 1-2 dB of attenuation at 2GHz). Level
has to be between +7 dBm and +10 dBm.
Connect coax cable parallel to 1st mixer to VCO-branch. A level of +5 dBm to +8 dBm due to decreased load
resistance over frequency band.
7.4
7.5
8.
Check of Attenuators:
8.1
8.2
8.3
8.4
8.5
Set -30dB attenuation to Tuner and to 0dB attenuation to TG.
Set Center Frequency to 500MHz, 100MHz/Div. span.
Connect tracking generator to tuner input.
TG-line has to be visible.
Switch on additional attenuators. Attenuation for each attenuator switch has to be 10dB (±1 dB)
9.
TG Level Adjustment:
9.1
9.2
9.3
9.4
9.5
9.6
9.7
Connect TG to reference analyzer.
Set HM5011 to Zero Scan and 500MHz Center Frequency.
Release all attenuator buttons of TG (0-dBm) and turn TG-level to maximum.
Adjust amplitude to +1dBm with Pot RV4 on TG.
turn TG-level to minimum.
Adjust amplitude to -10dBm with Pot RV3 on TG.
Amplitude has to be adjustable now between +1dB and -10dB.
10.
Final Check
10.1 Position of TG-level has to align in both bandwidths (400kHz and 20kHz). If necessary, align with IF-Amp.
10.2 TG-level knob has to be adjustable from +1 to -10dBm.
