Mask Testing 14On ErrorSource LockSourceTest AllThe On Error setting specifies the action(s) to take when the input waveformdoes not conform to the mask. This setting supersedes the Run Until setting.• Stop — The oscilloscope will stop when the first error is detected (on thefirst waveform that does not conform to the mask). This settingsupersedes the Minimum # of Tests and Minimum Time settings.• Save — The oscilloscope saves the screen image when an error isdetected. In the Save Menu (press [Save/Recall] > Save), select animage format (*.bmp or *.png), destination (on a USB storage device), andfile name (which can be auto-incrementing). If errors occur too frequentlyand 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 isdetected. This option is only available when a printer is connected asdescribed in “To print the oscilloscope's display" on page 215.• Measure — Measurements (and measurement statistics if youroscilloscope supports them) run only on waveforms that contain a maskviolation. Measurements are not affected by passing waveforms. Thismode 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 thesame 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 measureand stop on the first error..You can also output a signal on the rear panel TRIG OUT BNC connector whenthere is a mask test failure. See “Setting the Rear Panel TRIG OUT Source" onpage 228.When you turn on Source Lock using the Source Lock softkey, the mask isredrawn to match the source whenever you move the waveform. For example,if you change the horizontal timebase or the vertical gain the mask is redrawnwith the new settings.When you turn off Source Lock, the mask is not redrawn when horizontal orvertical settings are changed.If you change the Source channel, the mask is not erased. It is re-scaled to thevertical gain and offset settings of the channel to which it is assigned. Tocreate a new mask for the selected source channel, go back up in the menuhierarchy; then, press Automask, and press Create Mask.The Source softkey in the Mask Setup Menu is the same as the Sourcesoftkey in the Automask Menu.When enabled, all displayed analog channels are included in the mask test.When disabled, just the selected source channel is included in the test.Agilent InfiniiVision 2000 X-Series Oscilloscopes User's Guide 187
