What programming languages does the Keysight 34401A accept?
By default, the Agilent 34401A recognizes the SCPI programming language. You can also configure the 34401A to accept and execute the commands of either the Agilent 3478A multimeter or the Fluke 8840A/8842A multimeter. Remote operation will only allow you to access the functionality of the multimeter language selected.
You must always calibrate the Agilent 34401A using the SCPI language setting. The calibration commands from the other two multimeters will not be executed. The complete SCPI command set can be found in Chapter 4 of the 34401A User's Guide.
