This functionality is available on the 34972A only.
Syntax
MMEMory:FORMat:READing:RLIMit <row_limit>
MMEMory:FORMat:READing:RLIMit?
Description
This command allows you to specify whether the maximum number of sweeps that can be logged to a single USB data file should be limited to one less than 64K (216 - 1 = 65,535). If <row_limit> is ON, sweeps are stored in files named dat00001.csv, dat00002.csv, dat00003.csv, and so on, with 65,535 sweeps per file. If <row_limit> is OFF, data logged for the scan is stored in a single file named dat00001.csv, which is limited by both the space available on the USB drive and how the drive is formatted, up to a maximum of 232 sweeps (roughly 4.3 billion).
Parameters
Name Type Range of Values Default Value <row_limit> Boolean {OFF|0|ON|1} This is a required parameter. The factory default is ON.
Remarks
- This feature enables you to accommodate certain versions of common spreadsheet, database and data analysis programs that have limitations of 64K rows per file.
- When the instrument is shipped from the factory, the default state for <row_limit> is ON.
- The value of the <row_limit> will be saved in non-volatile memory on the instrument and will not be affected by *RST or SYSTem:PRESet.
Return Format
The query returns 0 (OFF) or 1 (ON).
