measurement parameter (usually S21).
<Ch>
Channel number.
<log_port>
Logical port number of a balanced port. If unspecified the numeric suffix is set to
1.
If an undefined balanced port or a single-ended port number is used, the
analyzer generates an error message.
Exception: Parameter ALL, see below.
ALL
If ALL is specified, all balanced ports are dissolved and the default port
configuration is restored; the <log_port> suffix is ignored.
If ALL is omitted, only the specified balanced port is dissolved.
SCPI, Command
Types
Device-specific, no query
Example:
See SOURce<Ch>:LPORt<log_port>
SOURce<Ch>:POWer<Pt>...
This subsystem controls the power of the internal signal source and provides output port settings.
Note: The SOURce<Ch>:POWer... subsystem comprises port-specific and general settings. Port-specific
settings are valid for the port specified by the numeric suffix <Pt> (...:POWER<Pt>:...). General settings
are valid for all test ports of the analyzer; the port suffix is ignored. Refer to the description of the individual
commands for more information.
SOURce<Ch>:POWer<Pt>:ATTenuation <numeric_value>
Sets a fixed attenuation factor for the generated wave at test port no. <Pt> and switches the attenuator
mode to MANual setting. The incident wave is attenuated via [SENSe<Ch>:]POWer:ATTenuation.
Use SOURce<Ch>:POWer<Pt>:ATTenuation:MODE AUTO for automatic generator attenuator
setting.
<Ch>
Channel number.
<Pt>
Test port number of the analyzer.
<numeric_value>
Attenuation factor for the generated wave.
Range [def. unit]
Depending on the analyzer/attenuator model, e.g. 0 dB to 80 dB [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, command or query
Example:
SOUR:POW -6
Set the internal source power for channel 1 to -6 dBm.
SOUR:POW2:ATT 10
Set the 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.
