Procedure. Follow the steps below to verify that the maximum operating
frequency (trigger operation) is functioning correctly.
1. Load the TP5TRIG.PDA test pattern file from the performance check disk.
2. Press the START/STOP button on the front panel. The LED, corresponding
to the button, should be on.
3. Verify that a stable data pattern as shown in Figure B-12 appears on the
oscilloscope screen.
4. Change the oscilloscope trigger source to CH4 and trigger slope to Rising
Edge.
5. Verify that a stable data pattern as shown in Figure B-13 appears on the
oscilloscope screen.
6. Press the START/STOP button on the front panel to stop output (the buttons
LED goes off).
