7.  Viewing Waveforms, Vectors,

and Pictures

Introduction

This chapter shows you how to view waveforms, vectors, and pictures using the MM-410
Waveform/Vector Rasterizing Monitor (MM-410) and the AVM-510A Series Automated Video
Monitors (AVM-510A). Sections in this chapter include:

• 

Waveforms:

– 

Displaying a waveform

– 

Setting a sweep rate

– 

Measuring a waveform with the graticule

– 

Setting waveform limit lines

– 

Switching PAL graticule to percent

– 

How to view a selected line

– 

Viewing a vertical interval

– 

Using filters

• 

Vectors:

– 

Viewing a vector

– 

Controlling the vector display

– 

Locking the vector to external sync

– 

Comparing two waveforms or vectors

– 

Setting waveform and vector images

– 

Locking and clamping the signal

• 

Pictures:

– 

Viewing a picture with waveforms

– 

Monitoring signal quality with Picture Guard

– 

Picture reference when the External Reference (Ext Ref) LED is on
