Pileup reject
Pileup reject will qualify the capture logic to reject those captures that include signals
with pileup conditions. This feature is useful when optimizing the pole/zero setting or
examining the baseline’s noise characteristics.
Trigger Mode
Trigger mode provides the ability to select from three options to Manually, Singularly,
or Continuously trigger the acquisition (captures) of the signals.
• If you select “Manual”, the scope will display the signals at the time the Trigger
button is pressed.
• If you select the “Single”, a single capture will occur; thereafter, you must press the
Arm button to re-enable the capture logic and wait for a new trigger condition to
occur. Pressing the Trigger button will force an unconditional trigger, and
therefore an unconditional capture even if no trigger condition exists.
• If you select “Continuous”, continuous captures will occur as long as the selected
trigger condition is met. No need to manually “Arm” the capture logic to allow it to
operate.
Trigger Source
The trigger source determines which signal will cause the acquisition of the signal.
Source options are as follows:
• Peak Detect • Store
• Slow Discriminator • External Gate In
• Fast Discriminator • Reject
• BLR Gate (Baseline Restorer) • Inhibit
Please refer to the Digital Traces, below, for an explanation for each trigger source.
Trigger Status
Status displays the current status of the trigger logic. The status will display “Waiting”
when the capture is waiting for a trigger condition, or “Triggered” when the trigger
condition has been satisfied, “Excessive Pileup” when there is an excessive pileup
condition, or “Not triggered” when there is no trigger present.
“Excessive Pileup” when the is an excessive pileup condition, Not triggered when there
is no trigger present.
