We're using ps6402/ps6403 devices with a sofware written on our own, distributed by our company to many customers. It has been working for the last 3 years without major problems.
we have implemented a solution that uses the isReady() function to poll continuously the scope after a runBlock call (trigger is armed). This looked to work fine so far. We recently noticed that this sequence may fail (isReady never returns "ready") especially when these API calls are performed just after system power-up. A second call to this API sequence without any restart of the scope will work.
So here are my questions :
- does the behavior of the DLL can be different just after its loading into the memory ?
- Shall we introduce a tempo between the isReady calls / use a callback model ?
Here are my versions : driver 188.8.131.52 / win7 pro 64bits
Thanks for your help.
