Mask Testing

Agilent InfiniiVision 2000 X-Series Oscilloscopes User's Guide 193
On Error The On Error setting specifies the action(s) to take when the input waveform
does not conform to the mask. This setting supersedes the Run Until setting.
• Stop — The oscilloscope will stop when the first error is detected (on the
first waveform that does not conform to the mask). This setting
supersedes the Minimum # of Tests and Minimum Time settings.
• Save — The oscilloscope saves the screen image when an error is
detected. In the Save Menu (press [Save/Recall] > Save), select an
image format (*.bmp or *.png), destination (on a USB storage device), and
file name (which can be auto-incrementing). If errors occur too frequently
and the oscilloscope spends all its time saving images, press the [Stop]
key to stop acquisitions.
• Print — The oscilloscope prints the screen image when an error is
detected. This option is only available when a printer is connected as
described in
"To print the oscilloscope's display" on page 231.
• Measure — Measurements (and measurement statistics if your
oscilloscope supports them) run only on waveforms that contain a mask
violation. Measurements are not affected by passing waveforms. This
mode is not available when the acquisition mode is set to Averaging.
Note that you can choose to Print or Save, but you cannot select both at the
same time. All other actions may be selected at the same time. For example,
you can select both Stop and Measure to cause the oscilloscope to measure
and stop on the first error..
You can also output a signal on the rear panel TRIG OUT BNC connector when
there is a mask test failure. See
"Setting the Rear Panel TRIG OUT Source" on
page 246.
Source Lock When you turn on Source Lock using the Source Lock softkey, the mask is
redrawn to match the source whenever you move the waveform. For example,
if you change the horizontal timebase or the vertical gain the mask is redrawn
with the new settings.
When you turn off Source Lock, the mask is not redrawn when horizontal or
vertical settings are changed.
Source If you change the Source channel, the mask is not erased. It is re-scaled to the
vertical gain and offset settings of the channel to which it is assigned. To
create a new mask for the selected source channel, go back up in the menu
hierarchy; then, press Automask, and press Create Mask.
The Source softkey in the Mask Setup Menu is the same as the Source
softkey in the Automask Menu.
Test All When enabled, all displayed analog channels are included in the mask test.
When disabled, just the selected source channel is included in the test.
