The Personal Daq/3000 Series modules feature a 16-bit/1-MHz A/D converter, 16 analog input channels
[user expandable up to 64], up to four 16-bit/1-MHz analog outputs, 24 high-speed digital I/O channels, 2
timer outputs, and four 32-bit counters.
All analog I/O, digital I/O, and counter/timer I/O can operate synchronously and simultaneously,
guaranteeing deterministic I/O timing amongst all signal types. The Personal Daq/3000 Series modules
include a high-speed, low-latency, highly deterministic control output mode that operates independent of
the PC. In this mode both digital and analog outputs can respond to analog, digital and counter inputs as
fast as 2µsec.
Other Hardware Features Include:

Encoder measurements up to 20 MHz, including Z-channel zeroing
Frequency and Pulse-width measurements with 20.83 nsec resolution
Timing mode: can measure the time between two counter inputs to 20.83 nsec resolution
Self-calibration
The Personal Daq/3000 series offers up to 4-MHz scanning of all digital input lines. Digital inputs and
counter inputs can be synchronously scanned [along with analog inputs] but do not affect the overall A/D
rate because they use no time slot in the scanning sequencer. For example, one analog input can be scanned
at the full 1-MHz A/D rate along with digital and counter input channels. The 1-MHz A/D rate is
unaffected by additional digital and counter channels.
Adding analog input channels to a Personal Daq/3000 Series module is easy. An additional 48 singleended
[or 24 differential] analog input channels can be added to each module with the optional PDQ30 expansion
module. The PDQ30 connects to the Personal Daq/3000 series card via an external cable. With the
Personal Daq/3000’s 1-MHz aggregate sample rate, users can easily add multiple analog expansion
channels and still have enough bandwidth to have a per-channel sample rate in the multiple kHz range.
Although the Personal Daq/3000 Series modules are powered via a USB port on a host PC, an external
power connector is available for cases in which the host PC’s USB port cannot supply adequate power, or
for when the user prefers a separate power source. The TR-2 is an optional power supply available for this
purpose. The TR-2 plugs into a standard 120VAC outlet and will supply 9VDC, 1 amp power to the
module via its external power connector.
