Data Access Map

Description

Puts formatted variant scalar data into the measurement result buffer. The data will be immediately processed and displayed. Subsequent changes to the measurement state will be reflected on the display.

Always precede this command by setting the format on the measurement to be consistent with the format of the data being sent to the analyzer.  In this way, the display annotation will be correct.

Execution of this command does not change the display format.

 VB Syntax

meas.putDataScalar format, data

Variable

(Type) - Description

meas

A measurement (object)

format

(enum NADataFormat) Format of the data. This value is presently ignored by the VNA. Data is always presented in the current format.

Choose from:

0 - naDataFormat_LinMag

1 - naDataFormat_LogMag

2 - naDataFormat_Phase

3 - naDataFormat_Polar

4 - naDataFormat_Smith

5 - naDataFormat_Delay

6 - naDataFormat_Real

7 - naDataFormat_Imaginary

8 - naDataFormat_SWR

9 - naDataFormat_PhaseUnwrapped

10 - naDataFormat_InverseSmith

11 - naDataFormat_Kelvin

12 - naDataFormat_Fahrenheit

13 - naDataFormat_Centigrade

Notes:

• The getData (variant) method includes a "format" argument, which allows scalar (one-dimensional) data. To put data back into the "raw" data buffer using this (putDataComplex) method, specify Polar format when using the getData method.

• Phase format accepts data in radians (not degrees) and displays in degrees. To convert to degrees:    radians * (57.29577951308233) = degrees. The getData method returns degrees if the request is for phase data.

data

(variant) - A 1-dimension array of single precision floating point numbers.

Return Type

Default

Examples

' Put 201 points worth of scalar data into the measurement
' 200 is max index, so 0 to 200 is 201 points
Dim data(200) ' array of 201 (scalar) data points
' Fill the array
For i = 0 to 200
data(i) = i/200
Next
app.ActiveMeasurement.putDataScalar 0, data
