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.

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.

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.

Signal Clipping and Badges

WARNING: Clipping is caused by excessive or dangerous voltage at the probe tip, and/or a vertical scale setting that is not

adequate to display the entire vertical range of the waveform. Excessive voltage at the probe tip can injure the operator and cause damage to the probe and/or instrument.

This instrument shows a warning triangle symbol and the words Clipping in a Channel badge when a vertical clipping condition exists. Any measurement badges associated with that channel also indicate a clipping condition by turning the measurement text red and listing the type of clipping (positive or negative).

To close the clipping message, change the vertical scale to show the entire waveform, disconnect the probe tip from the excessive voltage source, and check that you are probing the correct signal using the correct probe.

Clipping causes inaccurate amplitude-related measurement results. Clipping also causes inaccurate amplitude values in saved waveform files. If a math waveform is clipped, it will not af

About this task

Signal Path Compensation (SPC) corrects for DC level inaccuracies in the internal signal path, caused by temperature variations and/or long-term signal path drift. Failure to run SPC on a regular basis may result in the instrument not meeting warranted performance levels at low volts per division settings.

Before you begin

Disconnect all probes and cables from the front-panel channel inputs and rear-panel signal connectors.

Procedure

1. Power on and warm up the instrument for at least 20 minutes.

2. Tap Utility > Calibration.

3. Tap Run SPC. The SPC Status readout shows Running while SPC is running. SPC can take three minutes approximately per channel to run, so wait until the SPC Status message changes to Pass before reconnecting probes and using the instrument.

4. Close the Calibration configuration dialog when SPC has completed.

If the SPC fails, write down any error message text. Make sure that all probes and cables are disconnected and run the SPC again. If the SPC still fails, contact Tektronix Customer Support.

ou can abort the SPC calibration by tapping Abort SPC. This may leave some channels uncompensated,

Compensate the TPP Series probes

Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy.

About this task

The oscilloscope stores the compensation values for each probe/channel combination, and automatically recalls the compensation values when you plug in the probe. Probe compensation status is shown in the Probe Setup panel of the Channel configuration menu.

• If the Probe Compensation Status field displays Pass, the probe is compensated and ready for use.

• If the Probe Compensation Status field displays Default, the attached probe has not been compensated and needs to have this probe compensation procedure run.

• If the Probe Compensation Status field displays Fail, the attached probe has failed the probe compensation procedure. Reconnect the probe and run probe compensation again.

• If there is no probe compensation status field shown in the panel, the oscilloscope cannot store compensation values for that probe. See the oscilloscope Help for how to manually compensate passive probes not supported by the probe compensation function.

Before you begin

The oscilloscope must be powered on for at least 20 minutes before compensating a probe.

Procedure

Use this procedure to compensate supported TPP-family probes that show a Default status when connected to the oscilloscope.

Note: Doing a Default Setup does not delete probe compensation values. A factory calibration does delete all stored probe

compensation values.
