Procedure for manually entering calibration data into the HP 8340A:
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 fi r st 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 not
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 correct
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 connector
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.
