[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
. They are supported for compatibility
with FW versions < 1.5.
Suffix:
<Ch>
.
Channel number
<PhyPt>
Test port number of the analyzer
Parameters:
<AGCMode>
LNOise | LDIStortion | AUTO
AUTO
–
automatic/adaptive gain control (AGC) according to the
RF input level.
LNOise
–
fixed, large IF gain, for low input levels.
LDIStortion
–
fixed, small IF gain, for high 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

[SENSe<Ch>:]ROSCillator:EXTernal:FREQuency
<ExtClockFreq>
Specifies or queries the frequency of the external reference oscillator.
Suffix:
<Ch>
.
Channel number. This suffix is ignored in the ROSCillator sub-
system and can be set to any value.
Parameters:
<ExtClockFreq>
Frequency of the external reference clock signal. The frequency
must be 10 MHz; any other setting is ignored.
*RST:
10 MHz
Default unit: Hz
