| HP / Agilent 34907A Multifunction Module
The Agilent 34907A module for the 34970A
Data Acquisition/Switch Unit allows great flexibility for a variety of
sense and control applications. It combines two 8-bit ports of digital
input and output, a 100 kHz gated totalizer, and two ±12V analog outputs
- all on a single earth-referenced module. The digital inputs and
totalizer input may be included in a scan. Alarm limits for the digital
and event counter inputs are evaluated continuously, capturing and logging
alarm conditions even between scans.
Digital Input/Ouput
Use the digital outputs with an external
power supply to control microwave switches and attenuators, solenoids,
power relays, indicators, and more. Use the digital inputs to sense limit
switch and digital bus status. There are no complex handshake modes; reads
and writes are initiated either from the front panel or the bus.
Totalize Input
Count events from devices like photo
interrupters, limit switches, and Hall-effect sensors.
It keeps an updated total which can be read
via the front panel or programmatically at any time. With 26 bits of
resolution, it can count events at full speed for nearly 45 minutes
without an overflow.
Analog Output
Use the two electronically calibrated
analog outputs to source bias voltages to your device under test, to
control your analog programmable power supplies, or use the outputs as
setpoints for your control systems. The outputs are programmed directly in
volts, either from the front panel or from the bus.
