memory) or USB (external memory device). path is an absolute path and

State File Example
The following example shows the interaction between folders created from the
front panel and state files created/stored programmatically. For this sequence,
folder SETUP_1 was created on the internal flash drive from the front panel.
It is then specified (programmatically) as the current folder and a state file is
stored and recalled from that folder.
MMEM:CDIR “INT:\SETUP_1” // specify as current folder
configure instrument programmatically or from front panel
MMEM:STOR:STAT “test1.sta” // store the configuration
recall the configuration (state) at later date (even if
power is cycled)...
MMEM:LOAD:STAT ”INT:\SETUP_1\test1.sta” // load state
Saving States from the Front Panel
With the instrument configured as required, the state is stored from the front
panel as follows:
1 Use the Utility key and soft keys indicated on the previous page to set file
action ‘Store’.
2 Press the ‘ Browse’ soft key to display the ‘File System’ window. Use the front
panel knob to highlight the root directory or a folder in the counter’s
internal flash memory (Internal) or on the USB drive (External). If folders
are not visible, press ‘Browse’ again to view the directory structure.
