Keysight DAQ970A/DAQ973A - the Maximum Flexibility for Multi-Channel DAQ-Systems
With this modular instrument you can set up your individual, "tailor-made" measurement and test solutions. The device is a combination of DAQ system, 6½-digit multimeter, switching system (switches/multiplexers/matrix-switches) and data logger, based on a 3-slot mainframe and 8 different types of switching and I/O control modules. The DAQ970A is the advanced follow-up model of the well-known Keysight 34972A (also known as HP 34970A or Agilent 34972A). Add multiplexer-, actuator- or relay-matrix-modules according to your requirements. Ideal for example as a test stand system with multiple channels.
- Flexible mainframe for data acquisiton, multiplexing, datalogging and automatic test systems.
- Configure your individual solution according to your application and budget.
- 3 module slots (choice of 8 module types), for up to 20 2-wire- or 120 1-wire channels.
- Internal 6½-digit digital multimeter with enhanced accuracy and and speed.

Model Overview
| Model | Mainframe: Functions | Interfaces |
| DAQ970A | 3 slot mainframe for modules (8 module types available). Integrated 6½-digit multimeter and datalogger. Measurement functions: Voltage, current, resistance, capacity, frequency, diode, temperature; switching functions depending on modules. The autocalibration compensates for drifts in the internal DMM or on the DAQM907A multifunction module caused by time and temperature change. Built-in internal module calibration reduces thermal voltage offset errors. Soft keys for easy configuration; graphic color LCD; measurement display in multiple formats: Number, bar meter, trend chart, histogram. | USB host&device, Ethernet/LAN/LXI; command set compatible with SCPI and 34970A/34972A |

Frequently Asked Questions:
Question: What is signal switching and what exactly do the Keysight DAQ970A do?
Answer: Measurement in larger test systems must be fast, reliable, automated, and cost-effective. In doing so, many channels must be managed. This includes many measurement points on the DUT and many output test signals for stimulating the DUT on one side as well as a limited number of measurement instruments on the other side. What is needed, therefore, is a flexible, sensible and clear signal routing. This includes multiplexing of signals (e.g. many measuring points to one input of a measuring instrument), closing/opening signal paths and switching signals to different signal paths. This is what the Keysight DAQ970A does, while also having a built-in digital multimeter with data logger. The greatest flexibility is achieved through plug-in modules that combine different switching functions as needed.
Question: Are the modules/slots of Keysight DAQ970A and 34970A switch systems compatible?
Answer: No, all Keysight switching devices use their own plug-in modules. Only the two discontinued models 34970A and 34972A used the same plug-in modules. The DAQ970A, 34980A and 34970A/34972A series modules are not compatible with each other.
Question: When do I use a Keysight DAQ970A, when is a 34980A the better solution?
Answer: This is essentially a question of price per channel. For example, the DAQ970A supports up to 60 2-wire or 120 1-wire channels and is the ideal, space-saving solution for test systems of this size. As soon as the number of channels would require the purchase of two DAQ970As, you should alternatively think about a 34980A. Another decision criterion can be that more different plug-in module types are available for the 34980A. So keep in mind if you might need channels in the future that are only supported by modules of the 34980A series.
