Mixed Signal Oscilloscopes — MSO4000 Series, DPO4000 Series
Acquisition Modes
Mode Description
Sample Acquire sampled values
Peak Detect Captures glitches as narrow as 2 ns at all sweep
speeds
Averaging From 2 to 512 waveforms included in average
Envelope Min-max envelope reflecting Peak Detect data over
multiple acquisitions
Hi Res Real-time boxcar averaging reduces random noise
and increases vertical resolution
Roll Scrolls waveforms right to left across the screen at
sweep speeds slower than or equal to 40 ms/div
Waveform Measurements
Measurement Description
Cursors Waveform and Screen
Automatic
Measurements
29, of which up to four can be displayed on-screen
at any one time. Measurements include: Period,
Frequency, Delay, Rise Time, Fall Time, Positive
Duty Cycle, Negative Duty Cycle, Positive Pulse
Width, Negative Pulse Width, Burst Width,
Phase, Positive Overshoot, Negative Overshoot,
Peak-to-Peak, Amplitude, High, Low, Max, Min,
Mean, Cycle Mean, RMS, Cycle RMS, Positive
Pulse Count, Negative Pulse Count, Rising Edge
Count, Falling Edge Count, Area and Cycle Area
Measurement
Statistics
Mean, Min, Max, Standard Deviation
Reference Levels User-definable reference levels for automatic
measurements can be specified in either percent
or units
Gating Isolate the specific occurrence within an acquisition
to take measurements on, using either the screen,
or waveform cursors
Waveform Histogram A waveform histogram provides an array of data
values representing the total number of hits
inside of a user-defined region of the display. A
waveform histogram is both a visual graph of the
hit distribution as well as a numeric array of values
that can be measured.
