2.8.6.6 VSWR Limit Selection
This command sets the value of the output VSWR limit. If the limit is exceeded, a fault will be triggered, and
the RF output will be disabled.
Syntax:
VSWR:LIM <
selection
>
<selection>: 0 = None (Default)
1 = 6:1
2 = 3:1
3 = 2:1
Query:
VSWR:LIM?
Example 1:
To set the VSWR limit to 2:1, send the following command:
VSWR:LIM 3<LF>
Example 2:
To disable the VSWR limit, send the following command:
VSWR:LIM 0<LF>
Example 3:
To query the VSWR limit, send the following command:
VSWR:LIM?
Response:
0<LF>
2.8.6.7 ALC Mode
This command sets the mode of the Automatic Leveling Control (ALC) feature to either a default mode
(MANUAL) or a user-configurable mode (ALC INT).
In the default mode (MANUAL), the ALC Detector Gain, ALC Response, and ALC Threshold settings do not
affect the operation of the ALC feature because factory settings are used instead.
In the user-configurable mode (ALC INT), the ALC Detector Gain, ALC Response, and ALC Threshold
settings are used to configure the ALC functionality.
NOTE : For safety reasons, the user-configuration of the ALC feature cannot be used to force the amplifier to
exceed any RF output limiting that occurs when in the default (MANUAL) mode.
Syntax: MODE:<MANUAL|ALC<space>INT>
Query:
No (see the Amplifier State Query command)
Example 1:
To set the ALC to a default configuration, send the following command:
MODE:MANUAL<LF>
Example 2: To set the ALC to allow user configuration, send the following command:
MODE:ALC<space>INT<LF>
