Manual operation:
See
[SENSe<Ch>:]POWer:AGCMode:SAVE
Apply the static AGC (Automatic Gain Control) settings obtained during an AGC Learn-
ing Sweep.
Suffix:
<Ch>
.
Channel number
Example:
[SENSe<Ch>:]POWer:AGCMode:ACQuire
Usage:
Event
Manual operation:
See
[SENSe<Ch>:]POWer:AGCMode<PhyPt>:MEASure
<Mode>
[SENSe<Ch>:]POWer:IFGain<PhyPt>:MEASure
<AGCMode>
These two equivalent commands activate manual gain control and select the IF gain in
the measurement channels (b-waves). The IF gain in the reference channel (a-waves)
is set automatically if not otherwise defined using
.
Note:
These commands are replaced by
and
[SENSe<Ch>:]POWer:GAINcontrol:GLOBal
. They are supported for compatibility
with FW versions < 1.5.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
Parameters:
<AGCMode>
AUTO | LDIStortion | LNOise
AUTO
automatic/adaptive gain control (AGC) according to the RF input
level
LDIStortion
fixed, small IF gain, for high input levels
LNOise
fixed, large IF gain, for low input levels
*RST:
LDIS
Example:
*RST; :SENSe:POWer:IFG2:MEAS LNO; :SENSe:POWer:
IFG1:MEAS?
Optimize the received waves (measurement channel, b-waves)
at port 2 for small input levels and query the AGC settings for
the received waves at port 1. The response is
LDIS
.
