PS5000A window trigger
Hi,
I've got a problem with the setup of a window trigger using the API-functions. I use the PicoScope 5444D with API-functions in C++ mostly in block mode. I tried to setup a trigger window at the external trigger channel, where the measurement starts if the signal enters the window. This is the same as a falling edge trigger at the upper threshold and a rising edge trigger at the lower threshold. I'm using the ps5000aSetTriggerChannelPropertiesV2-, the ...ConditionsV2- and the ...DirectionsV2-functions to setup the trigger with threshold direction PS5000A_ENTER and threshold mode PS5000A_WINDOW. Unfortunately the picoscope uses both thresholds as rising edge triggers in this configuration. I didn't expect this behaviour for an enter-window-mode. Is there anything else to adjust for using this window trigger?

Re: PS5000A window trigger
Can we see your code to understand how you have called the functions. You can either post it here or send it to support@picotech.com
