Multiple use of 4424 units

Postby RKeyser » Mon Nov 05, 2012 1:19 pm

I am using the Pico Scope 4424. I have the requirement for measuring of 16 channels. Is it possible to connect multiple units of the 4424 on one PC and control all with one window (one instance of software running). I assume that one channel on each 4424 units will have to be used for a trigger. If software exists that enable use of multiple units may I please have a copy of it? Thanks

HI this is not something you can do, you will have one instance per scope.

The only other way to have them together is by writing your own software which obviously will take a little more work!

Synchronisation between units is not a guaranteed process though as there is not specific trigger to synch units together, the only way some kind of synchronisation can be achieved is if all 4 scopes have the same trigger signal going to all devices at the same time.

I have adapted example console application (provided in SDK) to run several oscilloscopes at once. Console means that you set all parameters in command window, or edit them in .txt setup file. I stopped after some successful preliminary tests with 3 units, so there could be some mistakes. If you interested to try I can provide it and some basic support (I do not program in C++ normally).

Note that if you need to synchronize several units you should use one channel for synchronization. Thus there only 3 channels to use in every units - means you basically need 6 units to measure 16-18 channels. Or you should admix synchro-puls to some channels of your measurements, which could be troublesome hardware task.
