[SENSe<Ch>:]POWer:ATTenuation ARECeiver | BRECeiver | CRECeiver | DRECeiver, <numeric_value>

Sets an attenuation factor for the wave received at test port no. <Pt>. The generated wave is attenuated automatically if step attenuators are available.

<Ch>

Channel number. If unspecified the numeric suffix is set to 1.

 

 

ARECeiver | BRECeiver | CRECeiver | DRECeiver

Test port of the analyzer, depending on the analyzer model:
Test port 1: ARECeiver
Test port 2: BRECeiver
Test port 3: CRECeiver
Test port 4: DRECeiver

<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, command or query

 

Example:

POW:ATT AREC, 10
Set an attenuation factor of 10 dB for the waves received at test port 1. The other test ports are not affected.

 

 

[SENSe<Ch>:]POWer:IFGain<Pt>:MEASure
AUTO | LNOise | LDIStortion

Selects the IF gain in the measurement channel b.

<Ch>

Channel number.

 

<Pt>

Test port number of the analyzer.

 

Parameters

AUTO – Adaptive Gain Control according to the RF input level
LNOise – Fixed, small IF gain, for high input levels  
LDIStortion – Fixed, large IF gain, for low input levels
 

*RST value

AUTO

 

SCPI, Command Types

Device-specific, command or query

 

Example:

POWer:IFG2:MEAS LDIS; POWer:IFG2:REF LNO

Optimize the measurement channel b for small input levels, the reference channel a for high input levels.
