Horizontal Delay. Use delay when you want to acquire a signal at a significant time interval
after the trigger point. Toggle delay on and off to quickly compare the signal at two different
points in time.
Average, Envelope, Hi Res Acquisition, and WfmDB. Use Average acquisition mode to
remove uncorrelated noise from your signal. Use Envelope to capture and display the
maximum variation of the signal. Use Hi Res to increase vertical resolution for lower
bandwidth signals. WfmDB mode is the only mode that can be used when mask testing with
an optical standard.
Signal Processing Features
Waveform Math. Set up simple math waveforms using the basic arithmetic functions
including FFT, or create more advanced math waveforms using the math expression editor.
Waveform expressions can even contain measurement results and other math waveforms.
Spectral Analysis. Display spectral magnitude and phase waveforms based on your time-
domain acquisitions. Control the instrument using the traditional spectrum analyzer controls
such as span, center frequency, and resolution bandwidth.
FastFrame. Use FastFrame to capture a series of triggered acquisitions at high resolution
without wasting acquisition memory on the dead time in-between the acquisitions.
Mask Testing. Use mask testing for signal violation detection and pass/fail testing. Test
signals against a user defined mask, or with Option SM you can test against industry standard
masks.
Limit Testing. Use Limit Testing for pass/fail comparison with an active signal.
Display Features
Color LCD Display. Identify and differentiate waveforms easily with color coding.
Waveforms, readouts, and inputs are color matched to increase productivity and reduce
operating errors.
Digital Phosphor. A Digital Phosphor Oscilloscope can clearly display intensity modulation
in your signals. The oscilloscope automatically overlays subsequent acquisitions and then
decays them to simulate the writing and decay of the phosphor in an analog oscilloscope CRT
(cathode-ray tube). The feature results in an intensity-graded or color-graded waveform
display that shows the information in the intensity modulation.
Fit to Screen. The Digital Phosphor technology performs the compression required to
represent all record points on the screen, even at the maximum record length settings.
MultiView Zoom. To take advantage of the full resolution of the instrument, you can zoom in
on a waveform to see fine details. Both vertical and horizontal zoom are available. You can
also zoom in on multiple areas of a single waveform simultaneously and on multiple
waveforms at the same time.
Measurement Features
Cursors. Use cursors to take simple voltage, time, and frequency measurements.
Automatic Measurements. Choose from a large palette of amplitude, time, histogram, and
communication measurements. You can customize the measurements by changing reference
levels or by adding measurement gating. Statistics (mean, maximum, minimum, standard
deviation and population) are available for each measurement value
