About Source Power Cal

Description

Note: This method replaces putSourcePowerCalData Method

Inputs source power calibration data (as variant data type) 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 Values command to return the X-axis values in the displayed order.

The calibration is not valid if the current number of points on the channel is not equal to the number of values that were input.

Note: This method sends variant data which is less efficient than methods available on the ISourcePowerCalData interface.

 VB Syntax

chan.putSourcePowerCalDataEx buffer, srcPort, data

Variable

(Type) - Description

chan

(object) – A Channel object

buffer

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

0 - naCorrectionValues   This is the only data buffer currently available.

srcPort

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

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.

data

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

Return Type

None

Default

Not Applicable

Examples

chan.putSourcePowerCalDataEx naCorrectionValues, 1, varData

C++ Syntax

HRESULT putSourcePowerCalDataEx(tagNASourcePowerCalBuffer bufSelect, long sourcePort, VARIANT varData);
