Description
The Agilent 34410A/11A/L4411A Multimeter provides a SCPI command set
that is enhanced, but highly backward-compatible with the Agilent 34401A
Multimeter. Nevertheless, due to the added features and enhanced
performance of the Agilent 34410A/11A/L4411A, there are some issues that
may prevent your 34401A program from running identically using the
34410A/11A/L4411A in its normal SCPI mode. For this reason, a 34401A
maximum-compatibility mode is provided.
The SYSTem:LANGuage command provides a compatibility switch, allowing
you to select the 34401A maximum-compatibility mode. In this mode the
34410A, 34411A, or L4411A instrument emulates the SCPI language for the
Agilent 34401A Multimeter (or the former HP 34401A version of that
product).
