Help topics
ESD Prevention Guidelines
Electrostatic discharge (ESD) can damage oscilloscope and some probe inputs. This topic discusses how to avoid this type of damage.
Electrostatic discharge (ESD) is a concern when handling any electronic equipment. The instrument is designed with robust ESD
protection, however it is still possible that large discharges of static electricity directly into the signal input may damage the instrument. Use
the following techniques to prevent electrostatic discharge from damaging the instrument.
• Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while connecting and disconnecting cables,
probes, and adapters. The instrument provides a ground connection to which to attach a wrist strap (on the Probe Comp ground
connector).
• A cable that is left unconnected on a bench can develop a large static charge. Discharge the static voltage from all cables before
connecting them to the instrument or device under test by momentarily grounding the center conductor of the cable, or by connecting a
50 Ω termination to one end, before attaching the cable to the instrument.
12
Preface
• Before you apply power, connect the instrument to an electrically-neutral reference point, such as earth ground. To do this, plug the
three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary to ensure safety and to
take accurate measurements.
If you are working with static sensitive components, ground yourself. Static electricity that builds up on your body can damage
•
static-sensitive components. Wear a wrist strap to safely send static charges on your body to earth ground.
• The oscilloscope must share the same ground as any circuits that you plan to test.

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.

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.

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: The Multipurpose knobs A and B move cursors and set parameter values in configuration menu input fields.
Selecting an menu field that can use a Multipurpose knob assigns the indicated knob to change the value in that input field. The ring
around each knob lights when you can use that knob to do an action. Push a Multipurpose knob to enable the Fine mode for making
smaller increment changes. Push the knob again to exit Fine mode.
FastAcq provides high-speed waveform capture that reduces the dead
3. Trigger controls:
• Force forces a trigger event at a random point in the waveform and captures the acquisition.
• Level

sets the amplitude level that the signal must pass through to be considered a valid transition. The color of the Level knob
LED indicates the trigger source except for dual-level triggers.
