CHECKSUM
24097*
Procedure for manually entering calibration data into the
SOURCE:
1.
Push the following sequence of KEYS:
[INSTR PRESET] [SHIFT] [MHz] [1] [2] [Hz] [SHIFT] [KHz] [2] [2] [Hz]
2.
Note the
Entry Display will indicate the Calibration Constant
number and value.
3.
Enter via the KEY
BOARD
or DATA
KNOB the
correct value for the
first Calibration Constant indicated
in
the
display.
«
Terminate KEYBOARD entries with the Hz key
»
4.
Go to
the next Calibration Constant by pushing the UP step key.
The next constant can then be entered- Do no
enter the
"CHECKSUM" Constant (This
is
computed automatically)
5.
The Step Keys can be used
to
move from one Calibration Constant to another to either check them
or
to correc
them.
6.
After all entries have been made, check that all numbers are correct by using the step keys to review and
verify
them
7.
Allow instrument to warm up for 1/2 hour and
make
sure that nothing
is
connected to the Stop Sweep connecto
on the rear panel. Press
[SHIFT PEAK]
to perform an Automatic Tracking Calibration.
This step may
modify
the
"YTM GAIN n" & "YTM BX GAIN
n" constants.
8.
The CALIBRATION data
should be permanently stored in
the Non Volatile Protected
Memory
by pushing
the
following key sequence [SHIFT]
[MHz]
[1] [4] [Hz] [SHIFT] [KHz] [5] [3] [4] [9] [Hz] [INSTR PRESET]
