Getting acquainted with your instrument
The following content provides a high-level description of the instrument controls and user interface. Refer to the instrument help for
detailed information on using the controls and user interface to display waveforms and take measurements.
Front panel controls and connectors
The front panel controls provide direct access to key instrument settings such as vertical, horizontal, trigger, cursors, and zoom. The
connectors are where you input signals with probes or cables, or insert USB devices.
Note: Refer to the instrument help for detailed information on using the controls to display waveforms and take measurements.

Acquisition and Cursors controls:
•
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.
•
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.
