■ Run/Stop starts and stops waveform acquisition. The button color indicates the acquisition status (green = running and
acquiring; red = stopped). When stopped, the oscilloscope shows waveforms from the last completed acquisition. The
Run/Stop button on the screen also shows the acquisition status.
■ Cursors button turns screen cursors on or off. Use the Multipurpose knobs to move the cursors. Double-tap the cursor
readouts, or on a cursor bar (line), to open the configuration menu to set cursor types and functionality. See
Display
and configure cursors on page 47.
■ Fast Acq
™
enables or disables the fast acquisition mode. FastAcq provides high-speed waveform capture that
reduces the dead time between waveform acquisitions, enabling the capture and display of transient events such as
glitches and runt pulses. It is helpful in finding elusive signal anomalies. Fast acquisition mode can also display
waveform phenomena at an intensity that reflects their rate of occurrence.
■ Single/Seq enables making a single waveform acquisition, or a specified number of acquisitions (as set in the
Acquisition configuration menu). Pushing Single/Seq turns off Run/Stop mode and takes a single acquisition. The
button color indicates the acquisition status (quick green flash = single acquisition acquired; solid green = waiting for
trigger event). Pushing Single/Seq again takes another single acquisition.
■ 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 at the bottom of the screen. The Horizontal badge also updates to show the sample rate and
record length settings while in High Res mode.
■ Clear deletes the current acquisitions and measurement values from memory.
2. Multipurpose knobs:
■ Multipurpose knobs (A, B) The Multipurpose knobs A and B move cursors and set parameter values in configuration
menu input boxes. Selecting an input box that can use a Multipurpose knob assigns the indicated knob to change the
value in that input box. The ring around each knob lights when you can use that knob to do an action.
