Alternate Programming Language Compatibility
You can configure the Agilent 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 can take advantage of the full functionality of the 34401A only through the SCPI programming language. For more information on selecting the alternate languages from the front panel menu, see “To Select the Programming Language,” on the previous page. From the remote interface, use the following commands to select the alternate languages:
L1 |
select SCPI language |
L2 |
select Agilent 3478A language |
L3 |
select Fluke 8840A language |
Virtually all of the commands available for the other two multimeters are implemented in the 34401A, with the exception of the self-test and calibration commands. You must always calibrate the 34401A using the SCPI language setting. The calibration commands from the other two multimeters will not be executed.
Be aware that measurement timing may be different in the alternate language compatibility modes.
Agilent 3478A Language Setting
All Agilent 3478A commands are accepted and executed by the 34401A with equivalent operations, with the exception of the commands shown below. Refer to your Agilent 3478A Operating Manual for further remote interface programming information.
