AMPTD Y Scale
I/Q Gain Ranges
See the following sections:
1 V Peak
“0.5 V Peak” on page 866
“0.25 V Peak” on page 867
“0.125 V Peak” on page 867
1 V Peak
Set the channel gain state to 1 Volt Peak.
0.5 V Peak
Set the channel gain state to 0.5 Volt Peak.
Notes: The POWer form of the command is provided for convenience. It maps to the
same underlying gain range parameter as the VOLTage form of the command.
The Reference Z (not the Q channel Input Z) is used to convert the power to
peak voltage, which is then used to set the Q Range as with the VOLTage form
of the command. The power values of the 4 range states (1V Peak, 0.5V Peak,
0.25V Peak, and 0.125V Peak) will vary with Reference Z. Here are some
examples:
50Ω: 10, 4, –2, –8
75Ω: 8.2, 2.2, –3.8, –9.8
600Ω: –0.8, –6.8, –12.8, –18.9
Preset: 10.0 dBm
Range: –20 dBm to 10 dBm
Min: –20 dBm
Max: 10 dBm
