OUTPut1

The OUTPut1 subsystem controls the characteristics of the Agilent E1446A’s “Main Output” BNC. The subsystem sets the output attenuation, sets the output source impedance, monitors overload conditions, and enables or disables the output.

Subsystem Syntax OUTPut1

 

:ATTenuation <attenuation>

 

:IMPedance <impedance>

 

:OVERload?

[query only]

[:STATe] <mode>

 

:ACTual?

[query only]

:ATTenuation

OUTPut1:ATTenuation <attenuation> controls the output attenuator of the “Main Output” BNC. Either no attenuation or 20 dB may be selected when OUTPut1:IMPedance is set to either 50or 75. OUTPut1:ATTenuation must be set to 0 dB when OUTPut1:IMPedance is set to 0.

:IMPedance

OUTPut1:IMPedance <impedance> sets the output impedance of the “Main

Output” BNC to either 0, 50Ω, or 75.

OUTPut1:IMPedance 0 should be selected when an open-circuit or high-impedance load is connected to the output of the Agilent E1446A. The matching impedance is removed from the amplifier output. Also, the OUTPUT1 offset voltage into an open-circuit is twice that into a matched load. Setting OUTPut1:IMPedance 0 compensates for this effect so that the SOURce:VOLTage:LEVel:IMMediate:OFFSet command will output the specified voltage into an open circuit.
