SCPI.CALCulate(Ch).SELected.DATA.FDATa

Object type

Property (Read-Write)

Syntax

All revision:

SCPI.CALCulate(Ch).SELected.DATA.FDATa = Data

Data = SCPI.CALCulate(Ch).SELected.DATA.FDATa

In revision A.9.60 and above, the following syntax is also supported:

SCPI.CALCulate(Ch).TRACe(Tr).DATA.FDATa = Data

Data = SCPI.CALCulate(Ch).TRACe(Tr).DATA.FDATa

Description

This command sets/gets the formatted data array, for the active trace of selected channel (Ch).
The array data element varies in the data format (specified with the SCPI.CALCulate(Ch).SELected.FORMat object). For more information on the formatted data array, see Internal Data Processing.

If valid data is not calculated because of the invalid measurement, “1.#QNB” is read out.

In revision A.9.60 and above, you can select the trace and set/get the formatted data array for the trace just by executing the above TRACe(Tr) command. You do not need to execute SCPI.CALCulate(Ch).PARameter(Tr).SELect.

Variable

Parameter	Data
Description	Indicates the array data (formatted data array) of NOP (number of measurement points)×2. Where n is an integer between 1 and NOP. Data(n×2-2) :Data (primary value) at the n-th measurement point. Data(n×2-1) :Data (secondary value) at the n-th measurement point. Always 0 when the data format is not the Smith chart format or the polar format. The index of the array starts from 0.
Data type	Variant type (Variant)
Note	If there is no array data of NOP (number of measurement point))×2 when setting a formatted data array, an error occurs when executed and the object is ignored.

Examples

Dim FmtData As Variant
SCPI.SENSe(1).SWEep.POINts = 201
SCPI.CALCulate(1).PARameter(1).SELect
FmtData = SCPI.CALCulate(1).SELected.DATA.FDATa
SCPI.CALCulate(1).PARameter(2).SELect
SCPI.CALCulate(1).SELected.DATA.FDATa = FmtData
