This section details the types of memory in the BTS Master, how to delete stored user files in internal memory, and recommended usage in a secure environment workplace.
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.
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.
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.
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.
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 CompactFlash memory for storage or data transfer. The external Flash USB can be reformatted using the BTS Master or sanitized using software on a PC.
Refer to the “File Management” for additional information on saving and copying files to the CompactFlash memory.

The BTS Master does not currently provide a secure erase feature. In environments where data security is an issue, it is recommended that users store their BTS Master created files on the CompactFlash memory or an external USB Flash drive that is then securely retained, sanitized, or destroyed after use.
