:SENSe:Z:METHod

Description

This command selects the measurement type of the impedance measurement (Z in :CALCulate:PARameter:DEFine). For more details about the different measurement types please refer to the general info page about measurements ( Measurement Types ).

Important

The standard behaviour of this method is that the input parameters (gain, attenuation, termination, ...) are kept. The optional DEFault parameter allows to apply measurement relevant default (preset) settings.

Command

Syntax	Parameter
`:SENSe<ch>:Z:METHod`	{ `P1Reflection` \| `TSHunt` \| `TSERies` \| `ECOupler` \| `EBRidge` \| `IADapter` \| `VCGain` }[,`DEFault`]

Parameters	accepted format	allowed suffixes	possible Errors	description
<`ch`>	{ `1` \| `empty` }	`none`	`Invalid channel index`	Currently only one channel is supported. `Empty` means `1` is used as default.
{ `P1Reflection` \| `TSHunt` \| `TSERies` \| `ECOupler` \| `EBRidge` \| `IADapter` \| `VCGain` }	exactly the given options	`none`	`Illegal parameter value`	The measurement to perform
[optional] `DEFault`	exactly the given options	`none`	`Illegal parameter value`	If applied the input parameters (gain, attenuation, termination, ...) are ALWAYS set to the default values; otherwise the settings from the previous measurement will be kept.

Query

Syntax	Response

Sample usage

Configure and start a P1Reflection measurement.

var visaSession = new TcpipSocket(VISA_RESOURCENAME);
visaSession.RawIO.Write(":CALC:PAR:DEF Z\n");
visaSession.RawIO.Write(":SENS:Z:METH P1R\n");
visaSession.RawIO.Write(":TRIG:SING\n");
// wait for the measurement to finish
visaSession.RawIO.Write("*OPC?\n");
visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":SENS:FREQ:DATA?\n");
var frequencyValues = visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":CALC:DATA:SDAT?\n");
var measurementValues = visaSession.RawIO.ReadString();

Python

visaSession.write(':CALC:PAR:DEF Z\n')
visaSession.write(':SENS:Z:METH P1R\n')
visaSession.write(':TRIG:SING\n')
visaSession.query('*OPC?\n')
frequencyValues = visaSession.query(':SENS:FREQ:DATA?\n')
measurementValues = visaSession.query(':CALC:DATA:SDAT?\n')
