Menus and dialog boxes
The Acquisition configuration menu
Use this configuration menu to set which data points are used to acquire waveforms, and enable automatically saving
acquisitions to files.
To open the Acquisition menu, double-tap the Acquisition badge on the Settings bar.
The Acquisition menu fields and controls
Displayed fields and controls can change depending on menu selections.
Field or control Description
Run/Stop Toggles the oscilloscope between constant acquisition (Run) and no acquisitions (Stop). When
stopped, the oscilloscope shows waveforms from the last completed acquisition.
Single/Seq Acquires a single acquisition or a set number of acquisitions, then stops.
Clear Erases acquired waveform data points from memory. Applies to all live acquisition waveforms.
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.
High Res mode also guarantees at least 12 bits of vertical resolution. The number of bits of
resolution is displayed in the Acquisition badge in the Settings bar.
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.
Average acquires and displays a waveform record that is the average result of several
acquisitions. This mode reduces random noise.
Single Sequence/Stop After Enables stopping acquisitions after a specified number of acquisitions. Only works when using
the Single/Sequence button.
