Instrument Security Procedures 1171.5702.52 ─ 02
Once the Signal Source Analyzer is outside the secured area, installing a second non-
classified removable compact flash memory (without any user data) allows the Signal
Source Analyzer to function properly for service or other needs.
Prior to re-entering the secured area, the non-classified removable compact flash
memory (without the user data) is removed. When the Signal Source Analyzer is back
within the secured area, the original classified removable compact flash memory can
be reinstalled.
●
To hold classified user data in secure areas, use the removable compact flash
memory (R&S
R&S
FSUP-B18) which comes with the instrument.
●
To hold non-classified user data in non-secure areas, use a second compact flash
memory (R&S
R&S
FSUP-B19).
Validity of instrument calibration after declassification
The calibration makes sure that measurements comply to government standards.
Rohde
&
Schwarz recommends that you follow the calibration cycle suggested for your
instrument.
The EEPROM is the only memory type used to hold permanent adjustment values
required to maintain the validity of the R&S
FSUP's calibration. Therefore, replacing
one removable compact flash memory with another, does not affect the validity of the
instrument’s calibration.
After an exchange of the removable compact flash memory, the board assembly
EEPROMs need to be registered once:
1. Turn off the instrument.
2. Turn the instrument back on while holding down the decimal point key [.] on the
number keypad on the front panel.
3. Continue to hold this key for 10 seconds after pressing the "On" button.
The instrument recognizes the changes and then powers up.
It is only necessary to perform these steps the first time the Signal Source Analyzer
returns from the service.
After exchanging the removable compact flash memory, perform a self-alignment once:
Note that the instrument has sufficient warm-up time before you perform the self-align-
ment.
1. Select the CAL key.
2. Select the "CAL-TOTAL" softkey.
This function uses the high-stability internal reference generator to produce the tempo-
rary adjustment values. Using the permanent and temporary values, the necessary
adjustment information is then stored on the compact flash memory. Rohde
&
Schwarz
recommends that you perform the self-alignment function once a week.
