About Source Power Cal

Description

Note: This method replaces putSourcePowerCalDataScalar Method

Inputs source power calibration data (as scalar values) to this channel for a specific source port.

The effect from this command on the channel is immediate. Do NOT send ApplyPowerCorrectionValuesEX after this command as it may invalidate the uploaded data.

If the channel is sweeping the source backwards, then the first data point is the highest frequency value; the last data point is the lowest. Use the Get X-Axis Values2 command to return the X-axis values in the displayed order.

 VB Syntax

chanData.putSourcePowerCalDataScalarEx buffer, srcPort, numValues, data

Variable

(Type) - Description

chanData

(interface) – An ISourcePowerCalData2 interface on the Channel (object)

buffer

(enum NASourcePowerCalBuffer) - The source power cal data buffer to write to.

0 - naCorrectionValues  This is the only buffer currently available.

srcPort

(long integer) – The source port for which calibration data is being input.

Note: If the port is defined by a string name, such as an external source, a balanced port, or one of the Source 2 outputs on the 2-port 2-source VNA-x model, then you must use chan.getPortNumber to translate the string into a port number. To learn more see Remotely Specifying a Source Port.

numValues

(long integer) – Number of data values being input.

Note:  If this does not equal the current number of points on the channel, the calibration will not be valid.

data

(single) – Array of source power cal data being input.

Return Type

None

Default

Not Applicable

Examples

Dim chanData As ISourcePowerCalData2
Set chanData = app.ActiveChannel
chanData.putSourcePowerCalDataScalarEx naCorrectionValues, 1, 201, scalarCalValues(0)

C++ Syntax

HRESULT putSourcePowerCalDataScalarEx(tagNASourcePowerCalBuffer bufSelect, long sourcePort, long numValues, float *pData);

Interface
