VectorStar™ MS4640A SeriesMicrowave Vector Network Analyzer : SCPI Commands : :CALCulate{1-16}:NFIGure Subsystem
 
:CALCulate{1-16}:NFIGure Subsystem
Use the Noise Figure commands to configure and measure noise figure values.
 
:CALCulate{1-16}:NFIGure:LOAD:DUT:S2P:DATA <char1>
Description
For the indicated channel, the command loads the DUT S2P data from the identified file. No query.
Cmd Parameters
<string> Filename and path in the form: ‘x:\directory\filename.S2P’ where x:\directory\filename.S2P must exist. See definition of <string>.
Query Parameters
NA
Output
NA
Range
NA
Default
NA
Syntax Example
:CALC1:NFIG:LOAD:DUT:S2P:DATA ’c:\AnritsuVNA\duts2pdatafilename.s2p’
:CALCulate{1-16}:NFIGure:LOAD:RECVer:OFFSet:DATA <filespec>

:CALCulate{CHAN,1-16}:NFIGure:RECVer:OFFSet[:STATe <char>
:CALCulate{CHAN,1-16}:NFIGure:RECVer:OFFSet:[STATe]?
Description
Turns on/off the state of noise figure receiver cal offset of the indicated channel.
Outputs the on/off state of the noise figure receiver cal offset of the indicated channel
Cmd Parameters

ON
:CALCulate{1-16}:NFIGure:NOISe:CALibration:PERForm?
Description
Query only. For the indicated channel, the command starts the noise figure calibration and then outputs the status on the given channel. Note that this command is only valid when the VNA is equipped with Option 041 – 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?
0
 
:CALCulate{1-16}:NFIGure:RMS:POINts <NRf>
:CALCulate{1-16}:NFIGure:RMS:POINts?
Description
For the indicated channel, the command 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. The query 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.
Cmd Parameters
<NRf>
Query Parameters

:CALC1:NFIG:RMS:POIN?
3000
 
:CALCulate{1-16}:NFIGure:TEMPerature?
Description
For the indicated channel, the query returns the standard temperature of 290 K that was used for the cold termination measurments. The IEEE standard temperature definition is 290 K.
Cmd Parameters
