General Information

1-17 Secure Environment Workplace

This section details the types of memory in the Spectrum Master, how to delete stored user
files in internal memory, and recommended usage in a secure environment workplace.

Spectrum Master Memory Types

The instrument contains non-volatile disk-on-a-chip memory, EEPROM, and volatile DRAM
memory. The instrument is also supplied with an external USB flash drive. The instrument
does not have a hard disk drive or any other type of volatile or non-volatile memory.
Disk-On-A-Chip (DOC)
DOC is used for storage of instrument firmware, factory calibration information, user
measurements, setups, and .jpg screen images. User information stored on the DOC is erased
by the master reset process described below.
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 parameter stored in the EEPROM are set to
standard factory default values.
RAM Memory
This is volatile memory used to store parameters 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. The user 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"
files to the USB flash drive.
