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
fect amplitude measurements on that math waveform.
Error Messages and Badges
This instrument shows a warning triangle symbol and an error message abbreviation in a Channel badge when an error occurs.
To remove the message from the badge, clear the error as indicated in the table.
Table 1: Probe errors
Error message Description
Prb Comm Accessory communication timed out. Please re-attach the accessory.
Prb ROM Unable to read probe ROM. Please re-attach the accessory.
Unsup Accessory is unsupported.
Prb Fault Critical accessory fault. Please re-attach the accessory. If the problem persists, contact
T
ektronix service.
Over Rng The signal voltage or current is over range. Please reduce the signal amplitude.
Temp The probe has experienced an over temperature condition. Please remove the probe from
the high temperature area.
