4 Click Start, then follow the instructions on the screen.
The routine will ask you to do the following steps:
a Disconnect everything from all inputs and Cal Out.
b Indicate whether you want to run time scale and interleave correction calibrations.
For a list of equipment required to perform the time scale calibration, refer to
the “Time Scale Accuracy (TSA) Test” section in the next chapter. The interleave
correction calibration requires a sine wave generator and a ≥ 67 GHz cable with
1.85 mm male connectors on each end. You will also need to use the two supplied
1.85 mm (f)- (f) connector savers. To learn more about both calibration options,
click Help.
c Connect the calibration cable from Cal Out to channel 1.
You must use the 54916- 61626 cable (channels 1- 4) or 54932- 61630 cable
(channels 1R and 3R) with two connector saver adapters for all oscilloscopes.
Failure to use the appropriate calibration cable will result in an inaccurate
calibration.
d Connect the calibration cable from Cal Out to each of the channel inputs as
requested.
e When instructed, connect the calibration cable from the Cal Out on the front
panel of the oscilloscope to the 1250- 1200 SMA(m) to BNC(f) adapter and then
connect the other end of the 1250- 1200 adapter to the 8120- 1840 BNC cable.
Connect the other end of the BNC cable to the Trig In on the rear of the
oscilloscope.
f A Passed/Failed indication appears for each calibration section. If any section
fails, click the Details box for information on the failures. Also check the
calibration cables.
5 After the calibration procedure is completed, click Close.
