SDK Enhancement suggestion: Open by serial number

It would be very convenient to have an SDK call to open a particular unit given its serial number. Our system employs 4x PS2205 units. Each unit is wired to a specific sensor, i.e. it is important for the software to be able to know which physical unit is which. The only method I've come up with is ...

PS2205: When is the trigger disabled?

I am using a PS2205 with an external trigger. As I understand it, the trigger (configured using ps2000_set_trigger()) is enabled by the call to ps2000_run_block(). What I would like to know is: When is the trigger disabled? 1) After it fires once? 2) By ps2000_get_values()? 3) By ps2000_stop()? 4) [...

(I hope I'm not speaking out of turn:) With the PS2205, I found I had to call ps2000_stop() after the acquisition (ps2000_ready() said "done"). I don't recall the symptom, but I'm pretty sure it occurred on the next ps2000_run_block() call. The PS3000 series might be different, but this seems like t...

OK, I think I see now: I was doing (what I think of as) "external triggering",
but that's not what "External Trigger"ing (capitalized) really means.

So it sounds as though I can do what I had in mind.

Thanks for your help.

Sorry, I'm feeling a bit dense here (:-)).
This is due to them both using the same connector.
My DAQ signal comes in on channel A. My DAQ trigger comes in on
channel B. My SIGNAL OUT connector is unoccupied. Am I missing
something?

Thanks for the response. I can't give up my DAQ trigger, and it's unlikely
we'll switch to the PS5000.

I'm still a bit unclear on the terminology, though: If the trigger and AWG
logic are independent, how do they interfere with one another?

One more: I tripped over this discussion: http://www.picotech.com/support/viewtopic.php?t=1193&highlight=generator+range Which seems to suggest that (for the PS3205) one cannot simultaneously use the AWG and an external trigger. Assuming I understood correctly: Does this apply to the PS2205 as well?

PS2205 AWG questions

I have a few small (I hope) questions about driving the PS2205 AWG. (I'll be using VB6 if that makes any difference.) 1) In the description of ps2000_set_sig_gen_arbitrary "sweeps" parameter, there is reference to a "trigger". Is there anything I need to do after calling this function, or does the A...

Workaround

I wrote (what amounts to) open_unit using open_unit_async, which gets
around the problem. The graphic still displays, but it goes away when the
open completes.

ps2000_open_unit progress indicator?

We are driving the PS2205 using a VB6 application. When ps2000_open_unit is called, a graphic box pops up ("PicoScope(tm)" and a progress bar). I don't mind the graphic, I guess, but if the open call fails, the graphic (typically) stays up until my program exits. I haven't found a way to close it or...

PS2205 hangs?

We have a pair of PS2205 units. From time to time, they appear to hang: The (WinXP) Device Manager says that they are operating properly, but neither our application nor Picoscope-6 can open them. When in this state, I don't hear any relay(?) clicks when the opens are attempted. Unplugging and re-pl...
