Introduction

• 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 can measure, as well as new diode, capacitance; 1nF – 100μF ranges, and strain measurements
• Auto-calibration, which compensates for drifts in the internal DMM; or on the DAQM907A multifunction module caused by time and temperature changes
• 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 DAQM900A solid-state multiplexer module
• 10 times more accurate and higher resolution DAC output and two additional voltage/current sensing channels with the DAQM907A multifunction 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

1. Functions and ranges – The DAQ973A is a superset of 34970A capability. See below for differences.
2. Measurement accuracy and resolution – The DAQ973A’s specifications are as accurate or better, with few exceptions.
3. SCPI compatibility – The DAQ973A will work with SCPI programs written for the Keysight 34970A/34972A. Listed below are the programming considerations and differences.
4. Mechanical size – Height, width, and depth dimensions are the same as the 34970A.
5. Accessories – Rack-mount kit accessories are compatible with both products. However, there are new part numbers for the rack-mount kits to be color-compatible with the DAQ973A.
6. Manufacturing – Both DAQs have the same rigorous quality standards and manufacturing process controls.
7. Service and support from Keysight – Our worldwide team is available to help you calibrate your DAQ970A/DAQ973A or answer any questions about either instrument.
