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 4.7.29, "Source step attenuators", on page 308).
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 526
SOURce<Ch>:POWer<PhyPt>:CONVerter:OFFSet <Value>, <Type>
Defines the power of a millimeter-wave converter, or its power offset relative to the
channel power (SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:
AMPLitude]).
Suffix:
<Ch>
.
Channel number
<PhyPt> Converter port number
Parameters:
<Value> Port-specific power or power offset, depending on the offset
<Type>.
Range: -300 dB to +300 dB (adjust to the converter's actual
source power range and the test setup)
*RST: 0 dB
Default unit: dB
