This subsystem controls the characteristics of the analyzer’s input ports.
Command tree: INPut
INPut<port_no>:ATTenuation
<numeric_value>Sets the attenuation for the received waves.
Note: INPut<port_no>:ATTenuation is not channel-specific; the value is valid for all channels. Use [SENSe<Ch>:]POWer<port_no>:ATTenuation to set or query a channel-specific attenuation value.
|
<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 received wave. |
|
Range [def. unit] |
Depending on the analyzer/attenuator model, e.g. 0 dB to 35 dB for ZVA24/ZVA24-B31/32 [dB]. UP and DOWN increment/decrement the attenuation in 5-dB steps. The analyzer rounds any entered value below the maximum attenuation to the closest 5-dB step. |
|
*RST value |
0 dB

|
SCPI, Command Types |
Confirmed, no query (query can not return channel-specific settings, would be misleading).
|
|
Example: |
Set the step attenuator for the wave received at port 2 and for all channels to 10 dB. The waves at the other test ports are not affected.
