Setting Input
Impedance
(Agilent E1405B
Commander)
This program uses the same commands and sequence as previously described, except for the OUTPut[1] commands shown below:
6. Set the amplifier output impedance.
OUTPut[1]:IMPedance <impedance>
7. Set the amplifier output attenuation.
OUTPut[1]:ATTenuation <attenuation>
