See "Main Memory" and "Boot ROM" in Table 1; "DSP Program Memory" and "DSP
Boot ROM" in Table 3.
Main Memory: 64 or 128 Mbits (See Table 1); Main Memory Boot ROM: 1 Mbit (see
Table 1); DSP Boot ROM: 1 Mbit (see Table 3); DSP Program Memory: 64 Mbits
The Flash memory can be cleared and sanitized by using the following "three-button
procedure:"
1. Turn the instrument off.
2. Turn the instrument back on while holding down the [ESC] key the [Return] key,
and the [View/Trace] key on the front panel. Continue to hold these three keys for
at least 10 seconds after turning the instrument back on.
3. The instrument will now clear the Flash memory. Allow at least 10 minutes for this
process to complete. There will be no visual indication of when it is done. Unplug
the instrument to turn it off; the Standby button will not work because its
instructions have been cleared out of memory.
This procedure complies with the clearing and sanitization requirements specified for Flash
in the "Clearing and Sanitization Matrix" referenced in DoD 5220.22M ISL 01L-1 section
8-301 as current on 06/27/2005.
Memory removal is not necessary for sanitization requirements

See "Recovering from Clearing the Instrument's Memory" following this
Configuration and calibration memory used to store the configuration and calibration
data, including serial and model number.
A7A4, A8, and A8A1A2: 20 kbits each; Options AYX (Table 2) and 1DN (Table 4):
4096 bits each
Since this memory contains instrument configuration and calibration data, there is no
way for the user to clear it without destroying the integrity of the instrument. Since this
information does not contain User information, sanitization is not required.
This memory need not be sanitized per compliance with the sanitization requirements
specified for EEPROM in the "Clearing and Sanitization Matrix" referenced in DoD
5220.22M ISL 01L-1 section 8-301 as current on 06/27/2005
