##### [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.
