Video and General Performance Verification Procedures
Composite Analog Field
Rate Tilt (Option CPS)
Apply a field rat
e square wave and use cursors to measure the tilt.
1. Set the waveform monitor to the factory presets. (See page 60, Incoming
Inspect
ion Tests.)
2. Connect the precision video generator to one of the CMPST A input
c
onnectors and terminate the other connector with the precision terminator.
3. Set the precision generator for Field Square Wave.
4. Press the Input C button to select the Composite A input.
5. Press the FULL button to make the WFM tile the full screen display.
6. Press the CURSORS buttontoturnonthecursorcontrols.
7. UsethearrowkeystoselectVolt1 and Volt2 and adjust the cursors to be near
the top of the waveform using the GENERAL knob.
8. Use the vertical knob to move the top of the waveform to the zero graticule.
9. Press and hold the GAIN button, select Gain Settings, and then select x5.
10. Press the GAIN button to close the menu.
11. Press the LINE SEL button use the left and right arrow keys t o select ALL.
12. Use the GENERAL knob to set the line select to a line number between
72 and 202.
13. Use the arrow keys to select Vol t1 and Vo lt 2 and use cursors to measure the
tilt in the waveform using the GENERAL knob to adjust them.
14. Record the value in the test record.
Composite Analog Line
Rate tilt (Option CPS)
Apply a field rate square wave and use cursors to measure the tilt.
1. Set the waveform monitor to the factory presets. (See page 60, Restore the
Factory Presets.)
2. Connect the precision video generator to one of the CMPST A input
connectors and terminate the other connector with the p recision terminator.
3. Set the precision generator for 100% Flat Field.
4. Press the Input C button to select the Composite A input.
5. Press the FULL button to make the WFM tile the full screen display.
6. Press the CURSORS buttontoturnonthecursorcontrols.
7. Use the arrow keys to select Volt1 or Volt2 and adjust cursors to be near the
top of the waveform using the GENERAL knob.
