Digital triggering architecture

In 1991, Pico Technology pioneered the use of digital triggering and precision hysteresis

using the actual digitized data. Traditionally, digital oscilloscopes have used an analog

trigger architecture based on comparators, which can cause time and amplitude errors

that cannot always be calibrated out. Additionally, the use of comparators can often limit

the trigger sensitivity at high bandwidths and can create a long trigger rearm delay.

Pico’s technique of fully digital triggering reduces trigger errors and allows our

oscilloscopes to trigger on the smallest signals, even at the full bandwidth, so you can

set trigger levels and hysteresis with high precision and resolution.

The digital trigger architecture also reduces the rearm delay. Combined with the

segmented memory, this enables you to use rapid triggering to capture 10000

waveforms in 10ms in 8-bit mode.

Advanced triggers

The PicoScope 5000D Series offers an industry-leading set of advanced triggers

including pulse width, runt pulse, windowed and dropout.

The digital trigger available on MSO models allows you to trigger the scope when any

or all of the 16 digital inputs match a user-dened pattern. You can specify a condition

for each channel individually, or set up a pattern for all channels at once using a

hexadecimal or binary value.

You can also use the logic trigger to combine the digital trigger with an edge or window

trigger on any of the analog inputs, for example to trigger on data values in a clocked

parallel bus.
