PicoScope® 6000E Series

Digital triggering architecture

Many digital oscilloscopes still use an analog trigger

architecture based on comparators. This causes time and

amplitude errors that cannot always be calibrated out and

often limits the trigger sensitivity at high bandwidths.

In 1991 Pico pioneered the use of fully digital triggering

using the actual digitized data. This technique reduces

trigger errors and allows our oscilloscopes to trigger on the

smallest signals, even at the full bandwidth. Trigger levels and

hysteresis can be set with high precision and resolution.

Advanced triggers

The PicoScope 6000E Series offers an industry-leading set

of advanced trigger types including pulse width, runt pulse,

windowed, logic and dropout.

The digital trigger available during MSO operation allows you

to trigger the scope when any or all of the 16 digital inputs

match a user-defined 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.

Alarms

PicoScope can be programmed to execute actions when certain events occur.

The events that can trigger an alarm include mask limit fails, trigger events and buffers full.

The actions that PicoScope can execute include saving a file, playing a sound, executing a program

and triggering the signal generator or the AWG.

Alarms, coupled with mask limit testing, help create a powerful and time-saving waveform

monitoring tool. Capture a known good signal, auto-generate a mask around it and then use the

alarms to automatically save any waveform (complete with a time/date stamp) that does not meet

specification.
