Setting the Output Impedance
Background The AFG-2000 output impedance can be set
to 50Ω or to High-Z.
When the output impedance is set to high-Z
the effect output is doubled compared to the
default 50Ω. For example, when the
amplitude is set to 10Vpp (impedance of 50Ω)
when the output impedance is switched to
high-Z, the amplitude becomes 20Vpp.
Note
dBm units are not supported for the high-Z
output impedance.
If the amplitude unit is dBm, and you switch to
the High-Z output impedance, the amplitude
unit will automatically change to Vpp.
If the output impedance is set to High-Z, you
cannot set the amplitude units to dBm. Change
the output impedance back to 50Ω first.
Panel Operation 1. To toggle the output
impedance between 50 and
High-Z, press
SHIFT+OUTPUT.
