Getting Started
If necessary, use an external attenuator first. Further, to prevent damage by
transients, use maximum RF attenuation when connecting a signal with a DC
component. Then remove attenuation as needed to make the measurement.
Also, be aware that the 2715 is optimized for a –30 dBm input to the first
mixer. A larger input signal may lead to nonlinear operation and inaccurate
results.
DO NOT connect a CATV trunk carrying AC power directly to the RF
INPUT. The 1st mixer can be overloaded making accurate measurements
impossible. Also, a power surge might raise the peak AC voltage above the
maximum safe input level.
CAUTION. The maximum safe RF and DC input levels are clearly printed near
the signal input jack (RF INPUT).
H
Do not apply incorrect AC input power
The 2715 will accept mains power up to 250 VACRMS (refer to Appendix A:
Specifications for additional information). It is unlikely that you will apply
incorrect power while using standard plugs and receptacles in the normal
working environment. However, in the field or during abnormal conditions,
you might have to connect temporary power. Be certain that any power
source connected to the 2715 applies less than 250 VACRMS between
conductors or between either conductor and ground. To avoid damage to the
source, ensure that it is rated for at least 120 W operation.
H
Do not allow moisture, dust, or other contaminants inside the case
Electronic circuits do not mix well with water, chemicals, dust, or grit. The
case is not water tight or air tight, so avoid exposing your instrument to these
or other contaminants. Do not place liquid containers on or near the
spectrum analyzer where they can be spilled into it. Use the Travel Line rain
cover (Option 33), or other suitable covering, when transporting the
spectrum analyzer outside in inclement weather.
H
Do not handle the spectrum analyzer with undue roughness
Do not physically abuse the spectrum analyzer. It can withstand a fair amount
of rough handling but dropping it off a workbench or bouncing it around the trunk
of a car or the back of a truck may cause damage. Protect the instrument while
transporting it, and use it where it cannot be accidentally hit, kicked, or dropped.
