Viewing Waveforms, Vectors, and Pictures
7-3
Under certain situations a 2 Field sweep rate is not available. For example, if you are unable to view
filters in Parade at the 2 Field sweep rate but you can see either the Luma or Chroma filter as two
fields. Also, you cannot display a vector with a waveform at the 2 Field sweep rate.
Figure 7-2. 1H Sweep Rate (A: 525 CPST)
The following table lists the sweep selections and sweep rates for the MM-410/AVM-510A.
Sweep Selection Sweep Rate
1H 5 µ/division (shows one line)
1H Magnified 0.1 µ/division
2H 10/division (shows two lines)
2H Magnified 1 µ/division
2 Field Shows two fields
2 Field Magnified Shows two fields expanded
Parade 15 µ/division
Parade Magnified 1 µ/division
Measuring a Waveform with the Graticule
The MM-410/AVM-510A lets you use special graticules for measuring waveforms. For example, you
can turn on amplitude limit lines so that all signal features above and below certain limits show up in
red. You can also turn on limit boxes to show where sync and blanking widths should be. If you are
using PAL, you can use a waveform graticule in volts or percent.
Using waveform limit lines and horizontal blanking boxes (called Added Marks), you can quickly
determine when signals are out of tolerance.
