Syntax and Commands

3-32 AFG3000 Series Arbitrary/Function Generators Reference Manual

OUTPut[1|2]:IMPedance

The OUTPut:IMPedance command sets the output load impedance for the specified

channel. The specified value is used for amplitude, offset, and high/low level

settings. You can set the impedance to any value from 1 Ω to 10 kΩ. The default

value is 50 Ω .

The OUTPut:IMPedance? command returns the current load impedance setting in

ohms. If the load impedance is set to INFinity, the query command returns

“9.9E+37”.

Group Output

Syntax OUTPut[1|2]:IMPedance{<ohms>|INFinity|MINimum|MAXimum}

OUTPut[1|2]:IMPedance?[MINimum|MAXimum]

Arguments <ohms>::=<NR3>[<units>]

where

<units>::=OHM

INFinity sets the load impedance to >10 kΩ.

MINimum sets the load impedance to 1 Ω.

MAXimum sets the load impedance to 10 kΩ.

Returns <ohms>::=<NR3>

Examples OUTPut1:IMPedance MAXimum

sets the CH 1 load impedance to 10 kΩ .
