Signal Generator Memory
Bit and binary files increase in size when the signal generator loads the data from non–volatile to
volatile memory. For more information, see “User File Size” on page 320.
Use the following SCPI commands to determine the amount of remaining memory:
Volatile Memory :MMEM:CAT? “WFM1”
The query returns the following information:
<memory used>,<memory remaining>,<“file_names”>
Non–Volatile Memory :MEM:CAT:ALL?
The query returns the following information:
<memory used>,<memory remaining>,<“file_names”>
NOTE The signal generator calculates the memory values based on the number of bytes used by the
files residing in volatile or non–volatile memory, and not on the memory block allocation. To
accurately determine the available memory, you must calculate the number of blocks of
memory used by the files. For more information on memory block allocation, see “Memory
Allocation” on page 311.
