Transition from Keysight 34970A to DAQ970A
Comparisons: DAQ970A/DAQ973A to 34970A/34972A
Data Acquisition System
The Keysight DAQ970A / DAQ973A is the next generation of data acquisition system (DAQ) for users of the Keysight 34970A or 34972A. The DAQ970A / DAQ973A design provides higher performance and greater flexibility while maintaining compatibility with the 34970A and 34972A.
The DAQ970A / DAQ973A improves the user experience with a color LCD, internal module calibration, and improved temperature accuracy and measurement speeds. A new DAQM900A solid-state multiplexer module is available for higher scanning speed. A new DAQM909A four-channel simultaneous sampling digitizer module captures fast transient signals from electromechanical devices.
Introduction
The 34970A and 34972A are legacy data acquisition and switching systems. Both designs provide ease of use with low cost per channel, modular flexibility, standard connectivity, and impressive measurement performance. They also offer the best combination of price and measurement performance.
The next-generation DAQ970A / DAQ973A builds on the proven design of the 34970A / 34972A.
Features
- Built-in advanced 6½-digit digital multimeter (DMM) and signal conditioning; no external boxes required; improved accuracy and speed
- The ability to measure very low current ranges; 1 µA DC and 100 µA AC and higher resistance range 1000 MΩ
- 11 measurement types that the 34970A / 34972A can measure, as well as new diode, capacitance, and strain measurements
- Auto-calibration, which compensates for drifts in the internal DMM or on the DAQM907A multifunction module or on the DAQM909A simultaneous sampling module caused by time and temperature changes
- An intuitive LCD screen and soft keys for easy configuration and measurement displays in multiple formats: number, bar meter, trend chart, and histogram
- Scan rate of up to 450 channels/sec with a new DAQM909A solid-state multiplexer module
- 10 times more accurate and higher resolution DAC output and two additional voltage- and current-sensing channels with the DAQM907A multifunction module
- 24-bit sampling rate of 800 kSa/s with a new DAQM909A four-channel digitizer module
- 20 computed channels that performs mathematical operations on readings from measurement channels, or other computed channels
- Test automation without programming using BenchVue’s DAQ software
Sample more signals, faster and dynamically, with DAQ970A / DAQ973A improvements:
• Up to 2x scan rate speed improvement; up to 450 ch/sec
• Up to 100x reading rates improvement to I/O interface and memory
• Up to 10x internal memory reading scans
• Up to 55% accuracy improvements for resistance
• Up to 75% accuracy improvements for AC voltage
• Up to 90% accuracy improvement for AC current
