Verifying Option 124, Y-Axis Video Out
6. Place the displayed signal at mid screen by pressing
Amplitude
, and
adjusting the reference level until the signal is as close as possible to
exactly mid screen. The voltmeter should read 0.5 volts.
7. Adjust the reference level to place the signal exactly on the top
graticule line. The voltmeter should read 1 V.
NOTE
The signal trace cannot be displayed above the top graticule line.
However, the analyzer will measure signals above the top graticule line.
Therefore the Video Output will be driven above 1 V even though it
appears the on screen trace is only at the top graticule line.
8. Adjust the reference level to place the signal on the bottom graticule
line. The voltmeter should read 0V.
9. Notice also that as the signal is moved up and down the screen, the
voltmeter reading changes 0.1V per graticule division.
Procedure 2 - Detailed view of the video signal
Connect channel 1 of the oscilloscope to the rear panel Video Out port of
the PSA.
Connect channel 2 of the oscilloscope to the rear panel Trigger 1 Out
port of the PSA. Trigger 1 on the PSA is the High=Sweeping (HSWP)
signal. Trigger 1 goes high just before the sweep starts on the analyzer
screen. These connections will allow the oscilloscope display to resemble
the PSA display.
