●No waveform displayed after signal acquisition:
① Check probe connection to signal cable.
② Check signal cable connection to BNC (channel connector).
③ Check probe connection to device under test.
④ Confirm device under test is generating signal.
⑤ Re-acquire the signal.
●Measured voltage amplitude differs from actual (common with probe use):
① Verify channel attenuation matches probe attenuation ratio.
●Waveform appears stepped:
① Horizontal time base may be too low; increase to improve resolution.
② If display type is Vector (lines between samples), switch to Point mode to remove stepped effect.
