/DAQ970A/MY00012345/20181127_134523123
would indicate a scan on instrument number MY00012345 that started approximately 23.123 seconds
after 1:45 pm (13:45) on November 27, 2018.
File Descriptions
The top level folder described above will contain two types of files. The first is a file named as follows:
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.
In addition to the config.csv file, you will have one or more data files named as follows:
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 soft-
ware. 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.
Contents of Data Files
Logging into data files is only supported for channels that are in the scan list. The possible channels are
shown in the table below; note that s stands for the slot number, which is 1, 2, or 3.
For example, the DAQM901A module supports could have channels 101-120, 201-220, or 301-320.
Module Description Channels
DAQM900A 20-channel FET multiplexer s01-s20
DAQM901A 20-channel, 2-wire armature multiplexer s01-s20
DAQM902A 16-channel, 2-wire reed multiplexer s01-s16
DAQM907A 2-channel DIO input s01-s02
DAQM907A 1-channel totalizer, 4-channel DAC s03, s04-s07
DAQM908A 40-channel, 1-wire armature multiplexer s01-s40
The format for all USB data files is similar to what Keysight BenchLink Data Logger produces by default.
The default field separator is a comma, but you can use the Seperator softkey to specify a different sep-
arator.
