Setting DC Offsets

(Agilent E1405

Commander)

This program uses the same commands and sequence as previously described, except for the OUTPut[1] and SOURCe:VOLTage commands shown below:

6. Set the amplifier main output impedance.

OUTPut[1]:IMPedance <impedance>

7. Set the amplifier main output attenuation.

OUTPut[1]:ATTenuation <attenuation>

8. Set the DC offset value.

SOURce:VOLTage[:LEVel][:IMMediate]:OFFSet <offset>

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.

2!This program uses the E1446A to generate an 8V DC offset for a

3!0.4 Vpp signal supplied by the E1445A AFG. To accomplish this, the

4!AFG signal is attenuated by 20 dB at the amplifier input. The amplifier

5!offset is set to 8V, the output impedance to 50 ohms, and the output

6!attenuation to 0 dB. Into 50 ohms, the 0.4 Vpp signal is centered on

7!8 volts.
