4.22 Source Subsystem - Voltage
This subsystem programs the output voltage of the Lx/Ls Series AC source.
Subsystem Syntax
[SOURce:]
VOLTage
:ALC

VOLTage:ALC[:STATe]
These commands select the various auto level control (ALC) modes. The ALC mode uses the
voltage measurement feedback to more precisely regulate the output voltage. The following ALC
modes can be selected:
ON | 0
This enables the ALC trip mode. If the programmed voltage cannot be
maintained, the output is disabled (relay opens) and a 801 Voltage error
is generated.
OFF | 1
This disables the ALC mode.
REG | 2
This enables the ALC regulation mode. The output voltage is regulated
based on the readback voltage but if regulation cannot be maintained, the
output does not trip off. Instead, a status bit is set in the Event Status
register to indicate the AC source is out of regulation. (This mode
requires firmware revision 0.98 or higher).
Note that the command format will take either alphanumeric or integer data but the query form
always returns numeric data (NR1).
