oscilloscope input.
• Set the calibrator to "level sine" and OPR/STBY to "OPR" mode.
• Set output of the calibrator to 5 MHz and the amplitude to 100
mVp- p.
• Press the Autoscale key.
• Set the time base to 50 ns/div.
• Set channel 1 to 100 mV/div.
• Decrease the output signal of the calibrator until 0.8 vertical division
of the signal is displayed.
• The trigger is stable when the displayed waveform is stable. If the
trigger is not stable, try to adjust the trigger level. If adjustment is
able to stabilize the waveform, the test result is still considered a
pass.
• Change the output signal of the calibrator to 40 MHz for the U1604B
or 20 MHz for the U1602B, and set the amplitude to 100 mVp- p.
• Press the autoscale key.
• Set the time base to 10 ns/div.
• Decrease the output of the calibrator until 1 vertical division of the
signal is displayed.
• The trigger is stable when the displayed waveform is stable. If the
trigger is not stable, try to adjust the trigger level. If the adjusment
able to stabilize the waveform, the test count is still considered a
pass.
