Calibration error; set up is out of order
Certain calibration steps require a specific beginning and
ending. Do not enter into the middle of a calibration
sequence.
Calibration Procedure
The only way to calibrate the instrument is by remote interface. Use a computer to perform the adjustment by first
selecting the required function and range on the measurement equipment. Send the calibration value to the
instrument and then initiate calibration.
You must unsecure the instrument before calibration.
A typical programming sequence for a single calibration setup is as follows:
1. CAL:SETup 2 (configures instrument for calibration step 2)
2. Measure the output frequency with the external frequency counter
3. CAL:VALue 9.99994321E6 (send the measured value to the instrument)
4. CAL? (initiates the calibration adjustment for setup 2)
5. Read CAL? query value to determine the failure (+1) or success (+0) of adjustment
6. CAL:SETup 3 (configures instrument for calibration step 3)
7. Perform the performance verification tests to verify the calibration.
For further information on instrument programming, refer to the
EDU33210 Series Programming Guide
.
If you abort a calibration in progress, all calibration constants for the selected function range are lost. If power
is turned off when the instrument is attempting to write new calibration constants to EEPROM, all calibration
constants for the selected function range may also lost. Typically, upon re–applying power, the instrument will
report Calibration Corrupt in the Questionable Data Register. Refer to the STAT:QUES:COND? command in the
EDU333210 Series Programming Guide
for more details. If this occurs, you should not use the instrument until
a complete re–adjustment has been performed.
Aborting a calibration in progress
Sometimes it may be necessary to abort a calibration in progress. You can abort a calibration at any time by turning
off the power or by issuing a remote interface device clear message followed by *RST. The instrument stores
calibration constants at the end of each adjustment procedure. If you lose power, or otherwise abort an adjustment
in progress, you will only need to perform the interrupted adjustment procedure again.
Sequence of adjustments
The adjustment sequence in the numbered steps minimizes the number of test equipment setups and connection
changes. You may perform individual adjustments as necessary, but setups 1 through 7 must be performed in order,
before any other setup procedure
