Use the Noise Figure commands to configure and measure noise figure values.
Note
These commands can be used for Noise Figure (Option 41) or for Differential Noise Figure (Option 48) for VNA B2 receiver in a 2-port DUT configuration.
Related subsystems for configuring and measuring noise figure include:
Starts the noise figure calibration and then outputs the status on the indicated channel.
Note that this command is only valid when the VNA is equipped with Option 41 – Noise Figure, and is in noise figure measurement mode. If the command is issued when the instrument is in Transmission/Reflection measurement mode, the command fails and returns a “1”.
Cmd Parameters
NA
Query Parameters
<NR1> 0 | 1
Output
<NR1>, where:
• 0 = Successful completion of the calibration
• 1 = Error in the calibration
Range
NA
Default
NA
Syntax Example
:CALC1:NFIG:NOIS:CAL:PERF?
:CALCulate{1-16}:NFIGure:RMS:POINts <NRf>
:CALCulate{1-16}:NFIGure:RMS:POINts?
Description
Sets the number of RMS (Root Mean Square) measurement points to be used in the noise power computation which sets the number of RMS measurement points for each sweep point for the indicated channel
Returns the number of measurements that were used in the noise power computation.
Note that the noise power measurements are for each sweep point. For example, if 3,000 RMS points and 51 sweep points are set, there are then 3,000 measurements for each of the 51 sweep points for a total of 3,000 × 51 = 153,000 total measurements.

Description
Query only.
Returns the standard temperature of 290 K that was used for the cold termination measurements.
The IEEE standard temperature definition is 290 K.
Sets the De-embed state for noise figure network extraction on the indicated channel. Returns the De-embed state for noise figure network extraction on the indicated channel.
