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.

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.
*RST

Key Entry
Ext ALC Hold Off On
: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
+0.00000
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.
