Spectrum Master UG PN: 10580-00277 Rev. E 1-11
Spectrum Master Memory Types
The instrument contains non-volatile disk-on-a-chip memory, EEPROM, and volatile DRAM
memory. The instrument does not have a hard disk drive or any other type of volatile or
non-volatile memory.
EEPROM
This memory stores the model number, serial number, and calibration data for the
instrument. Also stored here are the user-set operating parameters, such as frequency range.
During the master reset process, all operating parameters that are stored in the EEPROM
are set to standard factory default values.
RAM Memory
This is volatile memory that is used to store parameters that are needed for the normal
operation of the instrument along with current measurements. This memory is reset
whenever the instrument is restarted.
External USB Flash Drive (not included with the instrument)
This memory may be selected as the destination for saved measurements and setups for the
instrument. You can also copy the contents of the internal disk-on-chip memory to the
external flash memory for storage or data transfer. The external Flash USB can be
reformatted or sanitized using software on a PC.
Refer to the Chapter 4, “File Management” for additional information about saving and
copying files to the USB flash drive.
Warning
Note that when Frequency Blanking is turned on user files can still be stored and
saved to an external USB drive, and that frequency information is not blanked in
those files. Also, frequency information is not blanked from the SCPI commands
that are used to remotely control the instrument.
