Monitoring Signal Quality with Picture Guard (AVM-510A)

Picture Guard lets you watch a picture while monitoring certain signal elements or parameters. With a

System Video measurement screen selected, you can separately enable and disable up to 12 measured

items of video picture signal integrity. With Picture Guard enable, if one of the parameters goes

outside the tolerances you set, a small, rectangular icon pops up on the picture telling you which

parameter of the System Video measurement set has an error (see Figure 7-27).

NOTE:

When Picture Guard is enabled, the System Video measurement set, if not

selected, will automatically be selected. When Picture Guard is disabled, the

measurement set will be automatically changed back to the last measurement set selected

while not in Picture Guard.

You can activate Picture Guard using two methods: Press the Auto Meas button twice or the Split

Screen button twice. When you press the Auto Meas button the first time, the automeasure screen

appears. Pressing the Auto Meas button a second time turns Picture Guard on. When you press the

Split Screen button the first time, the picture with a quarter-size waveform and vector appear at the

bottom of the display. Pressing the Split Screen button a second time displays Picture Guard if

Picture Guard is activated. When Picture Guard is on, there is a small Magni logo in the lower-right

corner of the display. This sign shows you Picture Guard is on and not simply looking at the picture
