(Agilent E1405

Commander)

This program uses the same commands and sequence as previously described, except for the OUTPut2 and OUTPut3 commands shown below:

6. Set the amplifier ’Diff +’ and ’Diff -’ output impedances.

OUTPut2:IMPedance <impedance>

OUTPut3:IMPedance <impedance>

In this example, the E1446A is a servant to the E1405. As such, commands sent to the amplifier (at secondary GPIB address 11) are parsed by the Command Module rather than by the E1445A.
