<PhyPt>
Test port number of the analyzer
Parameters:
<AGCMode>
LDIStortion | LNOise
LDIStortion
0 dB gain, for high input levels
LNOise
10 dB 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 wideband / narrow-
band IF gain settings for the received waves at port 1. The
response is
LDIS
.
[SENSe<Ch>:]POWer:ATTenuation
<arg0>[, <arg1>]
Sets an attenuation factor for the received waves. This command is available if at least
one of the
is installed.
For redefined physical ports (see
measurement receiver (b-wave) is significant. E.g. if physical port 1 is equipped with a
step attenuator, then an attenuation factor can be applied to the (redefined) port receiv-
ing b1.
The generated wave is attenuated via
SOURce:POWer<Port_no>:ATTenuation
.
Suffix:
<Ch>
.
Channel number
Parameters:
<arg0>
Physical port number
Instead of port numbers 1, 2, 3 and 4 you can also use the con-
stants ARECeiver, BRECeiver, CRECeiver and DRECeiver,
respectively.
Default unit: n/a
<arg1>
Attenuation factor for the received wave.
Range:
0 dB, 10 dB, 20 dB, 30 dB. The analyzer rounds
any entered value below the maximum attenuation
to the closest step.
*RST:
0 dB
Default unit: dB
Example:
POW:ATT AREC, 10
Set an attenuation factor of 10 dB for the waves received at test
port 1 and channel no. 1. The other test ports and channels are
not affected.
