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 assembly 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 If you are calibrating an MSO model oscilloscope, follow the prompts to connect the

digital channels cable to the digital channels connector on the rear of the oscilloscope

and to the calibration connector on the MSO calibrator.

CAUTION Be sure to orient the digital channels cable with the Aglient part number facing

downward as shown on the rear of the oscilloscope. See Figure 2- 2.
