Field or control Description
Acquisition Mode
Sample creates a record point by saving one or more samples during each acquisition interval.
Sample mode is the default acquisition mode. The instrument does no post processing of the acquired
samples in this mode.
Peak Detect alternates between saving the highest sample in one acquisition interval and the lowest
sample in the next acquisition interval. Useful for capturing fast and random events such as narrow
waveform pulses.
High Res applies unique finite impulse response (FIR) filters based on the current sample rate. This
FIR filter maintains the maximum bandwidth possible for that sample rate while rejecting aliasing.
The filter removes noise from the oscilloscope amplifiers and ADC above the usable bandwidth for
the selected sample rate. Implementation of the filter in hardware, ahead of the trigger and storage,
reduces trigger jitter and enables using Fast Acq mode while in High Res mode.
The High Res sample rate and record length settings are displayed in the Horizontal badge. High Res
mode sets the maximum real time sample rate to ½ the maximum sample rate.
Envelope acquires and displays a waveform record that shows the extremes in variations over several
acquisitions. The instrument saves the highest and lowest values in two adjacent intervals (similar to
the Peak Detect mode). Unlike Peak Detect mode, the peaks are gathered over many trigger events.
A
verage acquires and displays a waveform record that is the average result of several acquisitions.
This mode reduces random noise.
FastAcq provides high-speed waveform capture. It is helpful in finding elusive signal anomalies. Fast
acquisition mode reduces the dead time between waveform acquisitions, enabling the capture and
display of transient events such as glitches and runt pulses. Fast acquisition mode can also display
waveform phenomena at an intensity that reflects their rate of occurrence.
Single Seq/Stops After
Enables stopping acquisitions after a specified number of acquisitions. Only works when using the
Single/Seq button.
Number of Waveforms
Specifies the number of acquisitions for average and envelope modes.
XY Display
Toggles XY display mode on and off.
Add Measurements configuration menu overview
Use this configuration menu to select measurements you want to take on waveforms and add the measurements to the Results bar
.
To open the Add Measurements configuration menu, tap the Measure button in the Analysis controls area.
The Add Measurements configuration menu always opens on the Amplitude Measurements panel. The listed panels and
measurements depend on the installed measurement options and the selected signal source.
