Trigger System
Source Channel 1 and Channel 2
Modes Auto, normal, single
Selections Edge, pulse width, pattern, video
Edge Trigger on a rising or falling edge of any source.
Pattern Trigger at the beginning of a pattern of high, low levels and rising or falling edge
established across any of the channels with conditions of AND, OR, NOR and NAND
between the channels.
Pulse width 200 ns to 10 s. Trigger when a positive or negative pulse width of any source larger
than, less than, equal to or not equal to duration.

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.
