FAQ • The input signal does not appear in the display. • I want to remove some contents from the display. • The waveform does not update (frozen). • The probe waveform is distorted. • Autoset does not catch the signal well. • I want to clean up the cluttered panel settings. • The accuracy does not match the specifications. • The oscilloscope will not allow a 2M waveform to be saved. The input signal does not appear in the display.
The waveform does not update (frozen). Press the Run/Stop key to unfreeze the waveform. See page 50 for details. For trigger setting details, see page 96. If this does not help, press the CH key. If the signal still does not appear, press the Autoset key. The probe waveform is distorted. You might need to compensate the probe. For details, see page 135.
The accuracy does not match the specifications. Make sure the device is powered on for at least 30 minutes, within +20°C~+30°C. This is necessary to stabilize the unit to match the specification. The oscilloscope will not allow a 2M waveform to be saved. Make sure that only 1 channel is active. Make sure that the signal has been triggered and that the STOP or Single key has been pressed. Ensure the time base is slower than 10 ns/div. See page 109.
