VectorStar™ MS464xB Series Microwave Vector Network Analyzer Programming Manual : SCPI Commands : :CALCulate{1-16}:NFIGure Subsystem
 
:CALCulate{1-16}:NFIGure Subsystem
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:

:CALCulate{1-16}:NFIGure:LOAD:DUT:S2P:DATA <char>
Description
Loads the DUT S2P data from the identified file for the indicated channel.
No query.
Allowed file types are .s2p, or .txt.
Cmd Parameters
<string> Filename and path in the form:
'x:\directory\filename.S2P', where x:\directory\filename.S2P must exist or 'x:\directory\filename.TXT', where x:\directory\filename.TXT must exist.
See Programming the VectorStar Series VNA, Notational Conventions for more information.

:CALCulate{1-16}:NFIGure:NOISe:CALibration:PERForm?
Description
Query only.
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.
