TRIGger Subsystem
Remarks: Normal baseband video has sync pulses on the bottom
of the waveform (use the
negative voltage). However, when the analyzer is used
to demodulate an NTSC or PAL TV RF carrier, the
detected video waveform is "upside down" with sync
pulses on the top of the waveform (use the
parameter for more positive voltage). When the
analyzer is used to demodulate a SECAM TV RF
carrier, the detected video waveform has normal
polarity (use the
