ASCII / CSV / DAT Source File Type

 

The ASCII / CSV / DAT file must contain I and Q data, and may also include marker data. The import function searches for markers, so it must know how many markers the file contains.

Source File

Enter the path to the source file you want to import, or select the Source File field, then use the Browse button to open a dialog window, then navigate to the desired file.

If no Q file or Marker file is selected then this file should contain lines of text with numbers in the following format:

I, Q, Mkr1, Mkr2, Mkr3, Mkr4

Use of Markers is optional.

Use Separate Q File

Double-click or use the drop-down menu to enable or disable the ability to use a separate file for Q data.

If Yes is selected, then only I data from the Source file is read.

Q Source File

Enter the path to the Q Source File you want to import, or select the Q Source File field, then use the Browse button to open a dialog window, then navigate to the desired file.

Data Type

Choices: Decimal | Hexadecimal

Default: Decimal

Double-click or use the drop-down menu to select data type.

This parameter is visible only when Source File Type is set to ASCII / CSV / DAT.

Swap IQ

Choices: Yes | No

Default: No

Double-click or use the drop-down menu to set the swap IQ flag. If it is set to Yes, IQ data will be swapped for waveform generation.

This parameter is visible only when Source File Type is set to ASCII / CSV / DAT.

Big / Little Endian

Choices: Big Endian | Little Endian

Default: Big Endian

Double-click or use the drop-down menu to select big or little endian for HEX data.

This parameter is visible only when Source File Type is set to ASCII / CSV / DAT and when the Data Type is set to Hexadecimal.

Signed / Unsigned Number

Choices: Signed | Unsigned

Default: Signed

Double-click or use the drop-down menu to select signed or unsigned type for HEX data.

This parameter is visible only when Source File Type is set to ASCII / CSV / DAT and when the Data Type is set to Hexadecimal.

Use Separate Marker File

Double-click or use the drop-down menu to enable or disable the ability to select a separate file for marker data.

If Yes is selected, then only I and Q data from the Source file is read.

Marker Source File

Enter the path to the Marker Source File you want to import, or select the Marker Source File field, then use the Browse button to open a dialog window, then navigate to the desired file.

This file should contain lines of text with numbers in the following format:

Mkr1, Mkr2, Mkr3, Mkr4

Set Use Separate Marker File to Yes to enable this parameter.

Use of Markers is optional.

Number of Markers

Displays the number of markers is defined in the imported waveform file. (Read-only)

Number of Points

Displays the number of points defined by the data files in the selected waveform. (Read-only)

Sample Rate

Range: 100.0 Hz to 200.0 MHz

Default: 100.00 MHz

Enter the waveform sample rate. Instrument Sample Clock is coupled with waveform Sample Rate and Oversampling Ratio.

Sample Clock = Sample Rate * Oversampling Ratio.
