Measurement System
Autoscale Finds and displays all active scope channels, sets edge trigger mode on highest numbered
channel, sets vertical sensitivity on scope channel. Requires voltage > 20 mVp-p, 0.5% duty
cycle and frequency > 100 Hz.
Automatic measurement Measurements continuously updated.
Voltage Peak-to-peak, maximum, minimum, amplitude, top, base, +overshoot, –overshoot, preshoot,
RMS, mean and one cycle mean.
Time Frequency, period, +width, –width and +duty cycle and –duty cycle on any channel.
Rise time, fall time, delay and phase shift.
Cursors
Manually place readout of horizontal (X
, DX) and vertical (Y, DY).
Waveform math CH1 + CH2, CH1 – CH2, CH2 – CH1
