1-17 Secure-Environment Workplace
This section describes 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 MS272xB model instruments contains non-volatile disk-on-a-chip memory, EEPROM,
volatile DRAM memory, and Compact Flash memory (internal and external). The instrument
also has a USB Type A interface (that can accept a USB flash drive). The instrument does not
have a hard disk drive or any other type of volatile or non-volatile memory.
The MS8911B has no disk-on-a-chip memory. The MS8911B has both internal and external
Compact Flash memory for application and user storage.
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
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.
Compact Flash Card
This memory may be selected as the destination for saved measurements and setups for the
instrument. The external Compact Flash Card can be reformatted or sanitized using software
on a PC. Refer to Chapter 4, “File Management”
