:EXTernal:HCRest

[:SOURce]:DM:EXTernal:HCRest[STATe] ON|OFF|1|0
[:SOURce]:DM:EXTernal:HCRest [STATe]?
Changes the operating condition to accommodate I/Q inputs with a high crest factor.
ON (1) Turns high crest mode on for externally applied signals with high crest factors.
High crest mode allows the N8211A/N8212A to process these signals with less distortion.
For crest factors higher than 4 dB, I/Q drive levels should be reduced by 1 dB for each dB
above that level. In high crest mode, the maximum output level is reduced and power level
accuracy is degraded.
OFF (0) Disables the high crest mode.
Example
:DM:EXT:HCR 0
The example disables the high crest mode.
*RST NORM
:EXTernal:POLarity
Supported N8212A
[:SOURce]:DM:EXTernal:POLarity NORMal|INVert|INVerted
[:SOURce]:DM:EXTernal:POLarity?
Selects normal or inverted I/Q signal routing. In inverted mode, the Q input is routed to the I
modulator and the I input is routed to the Q modulator.
Example
:DM:EXT:POL INV
The example inverts I and Q signal routing.
*RST NORM
