3 Set up the oscilloscope.
a Set channel 1 Coupling to DC.
b On 1 GHz, 500 MHz and 300 MHz models only, set channel
1 Imped to 50 Ohm.
c Press the Display key, then set the Vectors softkey to off.
d Press the AutoScale key.
e Set the time base to 20 µs/div.
f Press the Main/Delayed key, then set the Time Ref softkey to
Left.
g Adjust the Trigger Level knob to obtain a stable display.
4 Press the Quick Meas softkey, set the Source softkey to 1, then
press Select and choose Period. Press the Measure softkey and
measure the following:
Period 100 µs — The test limits are 99.8 µs to 100.2 µs.
If the measurements are not within the test limits, go to the
"Troubleshooting" chapter. Then return here.
5 Change the calibrator to 100 ns markers. Change the time
base to 20 ns/div. Adjust the trigger level to obtain a stable
display.
6 Measure the following. If the measurements are not within
the test limits, go to the "Troubleshooting" chapter. Then
return here.
Period 100 ns— The test limits are 99.8 ns to 100.2 ns.
7 Change the time base and calibrator markers as follows:
a On 300 MHz, 500 MHz, and 1 GHz models, change time
base to 2 ns/div and the calibrator to 5 ns markers
b On 100 MHz models, change time base to 5 ns/div and the
calibrator to 10 ns markers
