Description

This command selects the measurement value of the impedance measurement.

Command
Query

Syntax	Parameter
`:CALCulate<ch>[:SELected]:ZPARameter:DEFine`	{ `Z` \| `Y` \| `REFLection` \| `Cp` \| `Cs` \| `Lp` \| `Ls` \| `Rp` \| `Rs` \| `Q` \| `QTg` \| `D` }

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.
{ `Z` \| `Y` \| `REFLection` \| `Cp` \| `Cs` \| `Lp` \| `Ls` \| `Rp` \| `Rs` \| `Q` \| `QTg` \| `D` }	exactly the given options	`none`	`Illegal parameter value`	the type of the impedance measurement result

Syntax	Response
`:CALCulate<ch>[:SELected]:ZPARameter:DEFine?`	{ `Z` \| `Y` \| `REFLection` \| `CP` \| `CS` \| `LP` \| `LS` \| `RP` \| `RS` \| `Q` \| `QTG` \| `D` }

Parameters	accepted format	description
<`ch`>	{ `1` \| `empty` }	Currently only one channel is supported. `Empty` means `1` is used as default.

Response value	description
{ `Z` \| `Y` \| `REFLection` \| `CP` \| `CS` \| `LP` \| `LS` \| `RP` \| `RS` \| `Q` \| `QTG` \| `D` }	the type of the impedance measurement result

Options

Options	Description
`Cp`	Parallel capacitance
`Cs`	Serial capacitance
`D`	Dissipation factor (tan delta )
`Lp`	Parallel inductance
`Ls`	Serial inductance
`QTg`	Quality factor calculated based on the group delay time (Tg)
`Q`	Quality factor
`Rp`	Parallel resistance
`Rs`	Serial resistance
`Y`	Admittance
`Z`	Impedance
`REFLection`	Reflection

Important

All parameters except Y,Z and REFLection are represented as real numeric values and require therefore REAL for the selected measurement format :CALCulate[:SELected]:FORMat. All other formats result in a settings conflict error -221.

Presets

default value
{ `Z` \| `Y` \| `REFLection` \| `CP` \| `CS` \| `LP` \| `LS` \| `RP` \| `RS` \| `Q` \| `QTG` \| `D` }	`Z`

Sample usage

Configure and start a measurement of the serial capacitance.

C#
Python

var visaSession = new TcpipSocket(VISA_RESOURCENAME);
visaSession.RawIO.Write(":CALC:PAR:DEF Z\n");
visaSession.RawIO.Write(":CALC:ZPAR:DEF Cs\n");
visaSession.RawIO.Write(":CALC:FORM REAL\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();

Input:

visaSession.write(':CALC:PAR:DEF Z\n')
visaSession.write(':CALC:ZPAR:DEF Cs\n')
visaSession.write(':CALC:FORM REAL\n')
visaSession.write(':TRIG:SING\n')
# wait for the measurement to finish
visaSession.query('*OPC?\n')
frequencyValues = visaSession.query(':SENS:FREQ:DATA?\n')
measurementValues = visaSession.query(':CALC:DATA:SDAT?\n')
