Triggering the Oscilloscope
To use TV triggering
To use TV triggering
TV triggering is used to capture the complicated waveforms of television (TV)
equipment. The trigger circuitry detects the vertical and horizontal interval of
the waveform and produces triggers based on the TV trigger settings you have
selected.
The oscilloscope’s MegaZoom technology gives you bright, easily viewed
displays of any part of the video waveform. Analysis of video waveforms is
simplified by the oscilloscope’s ability to trigger on any selected line of the video
signal
1Press the More key in the Trigger section of the front panel, rotate the
Entry knob until
TV is displayed in the Trigger softkey, then press the
Settings softkey to display TV trigger menu.
2Press the
Source softkey and select any analog channel as the TV trigger
source.
The selected trigger source is displayed in the upper-right corner of the display.
Turning the Trigger Level knob does not change the trigger level because the
trigger level is automatically set to the sync pulse. Trigger coupling is
automatically set to TV in the Trigger Mode/Coupling menu.
