Agilent X-Series Signal Generators SCPI Command Reference 73
Basic Function Commands
Power Subsystem ([:SOURce]:POWer)
This command selects the external ALC Hold source. The ALC is held when the signal line is low
(0V) and is not held (i.e. leveling) when the voltage is a TTL high (5V).
With external triggering, the selected bi- directional BNC is configured as an input.
TRIGger1 This choice selects the TRIG 1 BNC as the external source for the ALC Hold
signal.
TRIGger2 This choice selects the TRIG 2 BNC as the external source for the ALC Hold
signal.
PULSe This choice selects the PULSE BNC as the external source for the ALC Hold
signal.
Example
:ALCH:EXT:SOUR PULS
The preceding example sets the external ALC Hold source to the PULSE BNC.
*RST TRIGger1
:ALCHold:EXTernal[:STATe]
Supported All Models
[:SOURce]:POWer:ALCHold:EXTernal[:STATe] ON|OFF|1|0
[:SOURce]:POWer:ALCHold:EXTernal[:STATe]?
This command enables (1) or disables (0) the External ALC Hold control. If Ext ALC Hold is on, the
external BNC input is selected using the :ALCHold:EXTernal:SOURce command.

:ALTernate:AMPLitude
Supported N5172B/82B
[:SOURce]:POWer:ALTernate:AMPLitude <val><units>
[:SOURce]:POWer:ALTernate:AMPLitude?
This command sets the delta value for the alternate amplitude.
The variable <val> is expressed in units of decibels (dB).
*RST
+0.00000000E+000
Range 174 to 174
Remarks The actual RF output amplitude is equal to the Alternate Amplitude Delta value plus the
RF output amplitude; this sum cannot exceed the minimum and maximum amplitude
limits of the signal generator. For example, if the Alternate Amplitude Delta is set to
174 dB and the RF output amplitude is set to 20 dB, the sum is equal to 154 dB.
