MEASURE MENU
The Measure menu gives direct access to over 30
measurements; the best operating mode is automatically
selected.
SCOPE MODE
Continuous Auto Set
Hands-free signal probing. Continuously follows input
signals from 15 Hz to 50 MHz and automatically selects the
proper time base, input range, and trigger level.
Min Max Envelope
Records the waveform excursions with a grey scale
envelope on both inputs.
40 ns Glitch detect
Sweep speeds 1 µs per division or slower on INPUT A.
Grey-scale display
Analog-like Grey-scale display.
Waveform Average
Smoothing up to 256 waveforms. 10 samples in Roll mode.
