Composite Analog Field
Rate Tilt (Option CPS)
Apply a field rat
e square wave and use cursors to measure the tilt.
1. Press FACTORY.
2. Press CONFIG, select Graticules and set Cmpst Waveform Graticule Units to
mV.
3. Connect the precision video generator to one of the Composite A input
connectors and terminate the other connector with the precision terminator.
4. Set the precision generator for Field Square Wave.
5. Press the C MPST A button, then the CURSOR button, and then the FULL
button.
6. Adjust cursors to be near the top of the waveform.
7. Use the vertical position knob to move the top of the waveform to the zero
graticule.
8. Press the 5x gain button and the FIELD button.
9. Use cursors to measure the tilt in the waveform.
10. Recor
d the value in the test record.
