CSA8000 & TDS8000 Instruments and Sampling Modules
H
Measurement menu, select Statistics.
1. Set the calibration value to default by sending the following GPIB com-
mand:
CALCOMP:DOUBLE “Internal10MHzRefFreq”,10e6
2. Enter the following GPIB command to turn the instrument’s cal constant
protection off:
SYST:PROT OFF
3. Click Run/Stop (button should be green).
4. Measurement menu, click Show Stats.
5. Record target value = (Mean value +1
m
s); where Mean is from the
Statistics window.
6. Horizontal menu, Timebase, Position, enter target value recorded in step 5.
7. Click Run/Stop (button should be gray).
8. Measurement menu, click Clear Stats.
9. Click Run/Stop (button should be green), wait 8 seconds then click Run/Stop
again (button should be gray).
10. Using the present Mean value from the Statistics window, and the
target value calculated in step 5,. Calculate the error and the new cal
constant:
Error = (mean – target value) / 1
m
s
New Cal Const = Error * 10e6 + 10e6
11. Input the new calibration constant into the instrument by sending the
following GPIB command:
CALCOMP:DOUBLE “Internal10MHzRefFreq”, New Cal Const where
New Cal Const is from Step 10.
12. Wait 8 seconds then save the mainframe factory calibration constants by
entering the following GPIB commands:
CAL:SAVE:FACT:MAI
13. Update the mainframe calibration time/date/temperature stamp by entering
the following GPIB command:
CAL:UPDATEINFO:MAI
14. Enter the following GPIB command to turn the instrument’s cal constant
protection on:
SYST:PROT ON
