Folder and file structure
Folder description
Each saved scan will be stored in a top-level folder named:
/DAQ97xA/[instrument_SN]/[yyyymmdd_hhmmssmmm]
– The square brackets ( [ ] ) are not part of the directory name.
– instrument_SN is the instrument's serial number.
– yyyymmdd_hhmmssmmm is a timestamp indicating the approximate start of the scan. The format is year (yyyy),
month (mm), day (dd), underscore (_), hours (hh), minutes (mm), seconds (ss), and milliseconds (mmm).
For example, the folder named: /DAQ970A/MY00012345/20191127_134523123 would indicate a scan on
instrument number MY00012345 started approximately 23.123 seconds after 1:45 pm (13:45) on November 27,
2019.
File description
The top level folder described above will contain two types of files.
1. config.csv
This is a text file that documents the instrument configuration for this scan. The timestamp is as described
above. This file lists the configuration of the instrument in a human readable form.
2. dat#####.csv
If you use the command MMEMory:FORMat:READing:RLIMit OFF, all of the data will be stored in one file,
named dat00001.csv.
You can issue the command MMEMory:FORMat:READing:RLIMit ON to limit the data to 64K - 1 (65,535)
sweeps per file, in which case the sweeps are stored in multiple files, named dat00001.csv, dat00002.csv,
dat00003.csv, and so on. This is helpful for importing data into spreadsheet or other data analysis software.
Note that some spreadsheet or data analysis software may import the data more easily if you change the
extension from csv to txt. If your software does not import the file correctly, try changing the extension on the
data file.
