Video and General Performance Verification Procedures
9. Press the GAIN b
utton to close the menu.
10. Use the cursors to measure the peak-to-peak deviation in the baseline of the
multipulse pa
ckets. Use the arrow keys to navigate between Volt1 and Volt2
and use the GENERAL knob to adjust them.
11. The peak-to
-peak deviation of the baseline is 0.1% per ns. For example, for
a 10 ns deviation on a 100 IRE signal yields a deviation of 1 IRE. Record
the measured value in the test record.
Composite Analog Pulse
to Bar Ratio (Option CPS)
Apply a pul
se and bar signal and use cursors to measure the difference b etween
the two.
1. Set the wa
veform 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 precision terminator.
3. Set the precision generator for a 2T Pulse and Bar.
4. Press the Input C botton to select the Composite A input.
5. Press the FULL button to make the WFM tile the full screen display.
6. Pres
stheCURSORS buttontoturnonthecursorcontrols.
7. Use the arrow keys to navigate b etween Volt1 and Volt2 and adjust the
curs
ors to be near the top portions of the waveform. Use the GENERAL
knob to adjust them.
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,andthenx10.
10. Press the GAIN button to close the menu.
11. Place one cursor on the top of the “Bar.” Use the GENERAL knob to a djust
Volt1 in the WFM tile.
12. Use the horizontal knob to put the “pulse” on the dotted line at the center
of the screen.
13. PressandholdtheMAG button and select x50 to expand the pulse
horizontally.
14. Press the MAG button to close the menu.
15. Position the second cursor on the top of the pulse. Select Vo lt 2 using the
arrow keys a nd use the GENERAL knob to adjust it.
16. Record the cursor delta in the test record.
