Digital Discovery: Portable USB Logic Analyzer and Digital Pattern Generator

[attila]

Hi Attila, we are looking to purchase digital discovery. However, the number of channels (pattern generator channels) within 1 unit is not sufficient for our application. May I check if it is possible to use 2 units of the Digital Discovery and make them work synchronously under the WaveForm software? Which will increase the pattern generator channels to 32. Looking forward to your reply. Thank you!

The Digital Discovery does not have dedicated trigger IOs, but for cross-triggering a Logic Analyzer DIN signal could be used.
This device does not have reference clock IO, so the two devices will run on independent oscillators, there will be a bit of jitter and shift over time.

The ADP3X50 and Analog Discovery 3 has trigger IOs and reference clock option as well WaveForms application support for dual mode, which lets you use 8/4 scope, 4 AWG channels, 32 DIOs.
On ADP3X50 the digital voltage/threshold is adjustable and the AD3 only supports 0/3.3V digital signals.
Dual support is also available for Analog Discovery1,2, EclypseZ7 but these lack reference clock.
