(4) There is a waveform displays but not stable:
①
Check the trigger source in the trigger menu and confirm that it matches the input channel of the actual signal.
②
Check the trigger type: Normal signals should use edge trigger mode. Stable waveform will be displayed only by setting
to the correct trigger mode.
③
Try changing the trigger coupling to high frequency suppression or low frequency suppression in order to filter out the
high or low frequency noise which might interfere the trigger.
(5) Pressing the RUN/STOP key and no waveform is displayed:
①
Check whether the trigger mode is normal or single, and whether the trigger level has exceeded the waveform range.
If so, center the trigger level or set the trigger mode to AUTO .
②
Press the AUTO key to complete the above settings automatically.
(6) Waveform refresh rate is too slow:
①
Check whether the acquisition mode is average, and the average times is large.
②
You can speed up the refresh rate by reducing the average times or select other acquisition mode such as normal
sampling.
Aside from specification labeled “typical”, all specifications are guaranteed.
Unless otherwise stated, all technical specifications are applicable to probes with attenuation 10X and UPO2000E series
oscilloscope. Oscilloscope must first meet the following two conditions in order to achieve these standards:
The instrument must be operated at the specified operating temperature for more than 30 minutes.
If the operating temperature range reaches or exceeds 5 degree Celsius, user must open the system function menu to
perform self-correcting.
