7Formats and Data Flow
206 Keysight 53210A User’s Guide
The command used to transfer data from reading memory to a file in internal flash
memory or on a USB device (Figure 7-1 and Figure 7-2) is:
MMEMory:STORe:DATA RDG_STORE, “<file>”
<file> is created during execution of the command and the file parameter format
is “[
drive:path]<file_name>”. drive is either INT (internal flash memory) or USB
(external memory device).
path is an absolute path and folder name. If a folder is
specified, it must have been previously created.
The combination of folder and file name cannot exceed 240 characters, and
cannot contain the characters \ / : * ? “ < > |.
The format of the transferred readings is specified by the
file_name extension. If
.csv is specified, the data is stored as comma-separated values (CSV) in one
measurement per line ASCII format. If
.dat is specified, the data is stored as REAL
values with little-endian byte order.
The following sequence of commands creates a folder on a USB memory device,
takes a set of frequency measurements, and then creates a file and copies the
measurements to the folder from (volatile) reading memory.
Creating a Data File Example
MMEM:MDIR “USB:\dut_1” // create folder in USB memory
MMEM:CDIR “USB:\dut_1” // specify a current folder
CONF:FREQ 100E3,(@1) // configure measurement
SAMP:COUN 50 // set 50 measurements
INIT // initiate measurements
*WAI // wait for readings to complete
MMEM:STOR:DATA RDG_STORE, “data1.csv” // create file, copy
