Glitch Off Does not capture glitches between samples. Smooth Suppresses noise from a waveform. Envelope Records and displays the minimum and maximum of waveforms over time. Auto Set (Connect-and-View) Continuous fully automatic adjustments of amplitude, time base, trigger levels, trigger gap, and hold-off. Manual override by user adjustment of amplitude, time base, or trigger level. Dual Input Meter The accuracy of all measurements is within ±(% of reading + number of counts) from 18 °C to 28 °C. Add 0.1x (specific accuracy) for each °C below 18 °C or above 28 °C. For voltage measurements with 10:1 probe, add probe uncertainty +1 %. More than one waveform period must be visible on the screen.
