Description
Overview
The Keysight 34907A is a multifunction module for the 34970A/34972A Data Acquisition/Switch Unit that combines digital I/O, event counting, and analog output capabilities. It provides 16 bits of programmable digital input/output, a 100 kHz 26-bit event counter, and two ±12V analog outputs for comprehensive control and monitoring in automated test systems.
Key Features
- Two 8-bit digital input/output ports (16 bits total)
- 26-bit event counter with 100 kHz input frequency and gated totalizer
- Two ±12V analog outputs with 10 mA per channel (40 mA maximum total per frame)
- Open-drain digital outputs for external relay and solenoid control
- Selectable input threshold for digital inputs
- Continuous alarm monitoring on digital and counter inputs
- Alarm conditions captured and logged even between scans
Applications
- Microwave switch and attenuator control
- Solenoid and relay switching with external power supplies
- Event counting and pulse accumulation from photo-interrupters and Hall-effect sensors
- Bias voltage sourcing for device characterization
- Analog control programming of external equipment
- Limit switch and digital bus status monitoring
Specifications
| 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. |
