Introduction

The 34970A and 34972A data acquisition systems are legacy data acquisition/ switching systems. Both designs are for ease of use with low cost per channel, modular flexibility, standard connectivity, and impressive measurement performance. The 34970A/34972A also offers the best combination of price and measurement performance. The next generation DAQ970A builds on the proven design of the 34970A and 34972A.
Features
  • Built-in advanced 6 ½ digit DMM & signal conditioning; no external boxes required, with 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
  • Eleven measurement types that the 34970A/34972A can measure, as well as diode and capacitance; 1nF – 100μF ranges
  • 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/s with a new DAQM900A solid-state multiplexer module
  • Ten times more accurate and higher resolution DAC output and two additional voltage/current sensing channels with the DAQM907A multifunction module
  • Test automation without programming using the BenchVue’s DAQ software
 
Compatibility
The DAQ970A design is compatible with the 34970A and 34972A with several exceptions. See Table 1 for product comparisons.
These are just some of the areas where the DAQ970A is equivalent with the 3497XA:
  1. Functions and ranges The DAQ970A is a superset of 34970A/34972A capability. Differences are listed below.
  2. Measurement accuracy and resolution The DAQ970A’s specifications are as accurate or better with few exceptions. 
  3. SCPI compatibility The DAQ970A will work with SCPI programs written for the Keysight 34970A/34972A. Programming considerations and differences are listed below.
 
Sample more signals, faster, with new DAQ970A improvements:
  1. Up to 2X scan rate speed improvement; up to 450 ch/sec
  2. Up to 10X reading rates improvement to I/O interface & memory
  3. Up to 55% accuracy improvements for resistance
  4. Up to 75% accuracy improvements for AC voltage
  5. Up to 90% accuracy improvement for AC current

4. Mechanical size Height, width, and depth dimensions are the same as the 34970A/34972A.
5. Accessories Rackmount kit accessories are compatible with both products. However, there are new part numbers for the rack mount kits to be color compatible with the DAQ970A.
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 or answer any questions about either instrument.
