SOURce<Ch>:POWer<PhyPt>:ATTenuation <arg0>
Selects a fixed mechanical attenuation for the generated wave at test port no.
<PhyPt>
.
This command is only available if the R&S ZNA is equipped with mechanical source
step attenuators (see Chapter 5.7.19, "Source Step Attenuators" , on page 225).
Suffix:
<Ch>
.
Channel number
<PhyPt> Test port number of the analyzer.
Parameters:
<arg0> Attenuation factor for the generated wave.
Range:
Mechanical attenuation can be set from 0 to 70 dB,
in steps of 10 dB.
Increment: 10 dB
*RST:
0 dB
Default unit: dB
Example: SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
SOUR:POW2:ATT 10
Set the mechanical step attenuator for the wave transmitted at
port 2 to 10 dB. The internal source power and the waves at the
other test ports are not affected.
Options:
Manual operation: See "Source Step Att." on page 404
SOURce<Ch>:POWer<PhyPt>:CORRection:GENerator<Gen>:LEVel:OFFSet
<Offset>
Specifies a gain (positive values) or an attenuation (negative values) in the signal path
between the external generator and the calibrated reference plane. The value has no
impact on the generator power.
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt> Calibrated port number. This suffix is ignored; the generator is
selected via
<Gen>
.
<Gen> Generator number
Parameters:
<Offset> Gain or attenuation value
Range:
-300 dB to +300 dB (adjust to the test setup)
Increment: 0.01 dB (other values are rounded)
*RST:
0 dB
Default unit: dB
