Based on sinusoidal or DC input signal. The maximum viewable signal while DC coupled is ±50 V
offset ±5 V/div at 4 divisions, or 70 V. AC coupling allows measuring signals on a DC level up to
300 V. For non sinusoidal waveforms, peak value must be less than 450 V. Excursions above
300 V should be less than 100 ms duration and the duty factor is limited to < 44%. RMS signal level
must be limited to 300 V. If these values are exceeded, damage to the instrument may result.
Line Trigger mode provides a source to synchronize the trigger with the AC line input.
Input Amplitude requirements: 85 V
Input Frequency requirements: 45 Hz - 440 Hz.

Positive or negative slope on any channel.
Coupling includes DC, HF reject, LF reject, and
noise reject.
Trigger on width of positive or negative pulses
that are >, <, =, or ≠ a specified period of time.
Trigger on a pulse that crosses one threshold
but fails to cross a second threshold before
crossing the first again.
