Specifying the File

When you save or recall a file, you must specify the file name with the extension. When you specify a file under a directory, delimit the directory and file names with a slash (/).

Saving Data to a File

You can use the following command to save the instrument setting, images on the LCD, measurement data for statistical analysis, list measurement results, and the contents of the setup table into a file:

The contents to be saved depend on the extension of the filename and the parameters specified when the command is executed. The table below lists the extensions, parameters, and corresponding contents to be saved.

Extension

Parameter

Contents to be saved

.sta

Not needed

Instrument state (instrument settings, calibration and compensation state) are saved. For the instrument settings to be saved, see Default Conditions.

.bmp

Not needed

Images *1 are saved in the bitmap format. If no images exist on the clipboard, the images of the LCD are stored on the clipboard when the command is executed, then they are saved.

.png

Not needed

Images *1 are saved in the portable network graphics format. If no images exist on the clipboard, the images of the LCD are stored on the clipboard when the command is executed, then they are saved.

.csv

LOG

or

omitted

Measurement data for statistical analysis  are saved in the ASCII format (as comma-delimited data). If the frequency of data measurement stored on the volatile memory exceeds 65,536, only the data acquired from the first 65,536 measurements are saved and the remaining data are ignored.

LIST

Measurement results of list measurement at all measurement points are saved in the ASCII format as comma-delimited data. Measurement results of single-point measurement cannot be saved.

SETup

The contents of all of the measurement point (stimulus) setup tables, the contents of all of the calibration kit setup tables, and the contents of all of the compensation kit setup tables are saved in the ASCII format as comma-delimited data.

COMParator

The contents of all of the BIN sorting setup tables are saved in the ASCII format as comma-delimited data.

.dta

Not needed

Measurement data for statistical analysis  are saved in the binary format. Regardless of how many times measurement is executed, all of the stored measurement data are saved.

Recalling a File

To recall an .sta or .csv file that contains previously saved instrument settings, use the following command:

The contents to be recalled depend on the extension of the filename and the parameters specified when the command is executed. The table below lists the extensions, parameters, and corresponding contents to be recalled.

Extension

Parameter

Contents to be recalled

.sta

Not needed

Instrument state (instrument settings, calibration and compensation state) are recalled.

.csv

SETup

or omitted

The contents of all of the measurement point (stimulus) setup tables, the contents of all of the calibration kit setup tables, and the contents of all of the compensation kit setup tables are recalled.

COMParator

The contents of all of the BIN sorting setup tables are recalled.

Automatically Recalling a File

When the E4982A is turned ON, it looks for an instrument settings file named “autorec.sta” and, if the file exists, automatically recalls the settings from the file.

Managing a File

To manage files, use the following command:

Copies a file

:MMEM:COPY

Creates a new directory (folder)

:MMEM:CRE:DIR

Deletes an existing file or directory

:MMEM:DEL

Reads the information about the storage device built in the E4982A

:MMEM:CAT?
