Check if stable trigger.
Figure 1–18: Measurement of Trigger Sensitivity — 50 MHz Results
Press SET LEVEL TO 50%. CHECK that a stable trigger is
obtained for the test waveform on both the positive and negative
slopes. Press the main-menu button Slope; then use the side menu to
switch between trigger slopes. Use the TRIGGER LEVEL knob to
stabilize the trigger if required.
Enter the pass/fail result on the test record.
Leave the Main trigger system triggered on the positive slope of the
waveform before proceeding to the next check.
Press the main-menu button Source; then press the side-menu button
–more– until CH 1 appears. Press CH 1.
4. Confirm that the Main and Delayed trigger systems are within sensitivity
limits (500 MHz):
a. Hook up the test-signal source: Disconnect the hookup installed in
step 1. Connect the signal output of a high-frequency sine wave
generator (Item 19 or, optionally, Item 26) to CH 1.
b. Set the Main and Delayed Horizontal Scales:
Set the horizontal SCALE to 500 ps for the M (Main) time base.
