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.
