Procedure for manually entering calibration
data into the HP 8340/41
B:
1.
Push the following sequence of KEYS:
Instrument 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. Push
SHIFT PEAK to perform an Automatic Tracking Calibration. This step may modify the
"YTM GAIN n" & "YTM BX GAIN
n" consts.
8.
The CALIBRATION data should be permanently stored
in
the Non Volatile Protected Memory by pushing
the
following key sequence:[SHIFT] [MHz]
[14] [Hz] [SHIFT] [KHz] [5349] [Hz] [PRESET].
