OUTPut<port_no>:ATTenuation
[Deprecated command]
Sets an attenuation factor for the generated wave transmitted at test port no. <Pt>. The incident wave is
attenuated via INPut<Pt>:ATTenuation.
OUTPut<Pt>:ATTenuation is not channel-specific; the value is valid for all channels. Use
SOURce<Ch>:POWer<Pt>:ATTenuation to set or query a channel-specific attenuation value.
Use SOURce<Ch>:POWer<Pt>:ATTenuation:AUTO ON for automatic generator attenuator setting.
Automatic attenuator setting overwrites the manual attenuation factor. Conversely, a manual entry resets
the mode to manual (OFF).
<port_no>
Test port number of the analyzer, 1 to 2, 3 or 4, depending on the analyzer
model. If unspecified the numeric suffix is set to 1.
<numeric_value>
Attenuation factor for the generated wave.
Range [def. unit]
Depending on the analyzer/attenuator model, e.g. 0 dB to 80 dB for ZVA8 with
ZVA8-B21/B22/B23/B24 [dB]. UP and DOWN increment/decrement the
attenuation in 10 dB steps. The analyzer rounds any entered value below the
maximum attenuation to the closest step.
*RST value
0 dB
SCPI, Command
Types
Confirmed, no query (query cannot return channel-specific settings, would be
misleading).
Example:
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
OUTP2:ATT 10
Set the step attenuator for the wave transmitted at port 2 and for all channels to
10 dB. The internal source power and the waves at the other test ports are not
affected.
SOUR1:POW2:ATT?
Query the generator step attenuator setting at port 2 and for channel no. 1. The
response is 10.
OUTPut<Chn>:DPORt PORT1 | PORT2 | PORT3 | PORT4
[Deprecated command]
Selects a source port for the stimulus signal (drive port). The setting acts on the active trace. The effect of
the drive port selection depends on the measurement parameter associated to the active trace:
 If an S-parameter S
<out><in>
is measured, the second port number index <in> (input port of the DUT
= drive port of the analyzer) is set equal to the selected drive port: Drive port selection affects the
measured quantity.
 If a wave quantity or a ratio is measured, the drive port is independent of the measured quantity.
Note: This command is equivalent to [SENSe<Chn>:]SWEep:SRCPort.
<Chn>
Channel number used to identify the active trace. If unspecified the numeric
suffix is set to 1.
