AWG query

Hi all,
I would like to use the AWG on a 2205 to generate a 38kHz square wave which is then switched on and off at 10ms intervals.

Can anyone direct me as to how (or even if?) this can be done in PicoScope 6?

Many thanks.

Re: Reading same values on both channels of PicoScope 2204

The only thing I can see strange in your code (after a quick look) is that you are using PS2000_RISING for your trigger on CHANNEL B, but you say you have channel B shorted to ground.

For the benefit of the list lurkers... This turned out to be quite straightforward. The Windows API call you need is : RegisterDeviceNotification(...) With this you register for device notifications, and then you add a message handler to your program which gets called when a WM_DEVICECHANGE arrives....

Robin,
Thanks again - that sounds like exactly the type of thing I'm looking for.
I'll check MSDN and google....

BTW, I'm using VC 9.0. (Visual Studio 2008) but not .Net

Detecting a scope before calling ps2000_open_unit

In my new product I'd like to be able to detect if there is a Pico Scope attached before calling ps2000_open_unit(). The reason is that I wish the make the UI as slick and user friendly as possible, so I don't want to do user-nagging such as "Please attach your scope and hit 'connect'", and I can't ...

Thanks Robin,

It's not causing me any trouble, I just check for !=0 at the moment, but it would be nice to know for sure.

Thanks again for the very quick replies - you are putting other companies to shame in the speed of your support replies.

Kind regards
Hi Ziko,

The 'scope is a Pico 2105 handheld.
PS2000.dll is version 2.0.8.3
PicoPP.sys is version 1.13.2
The SDK is version 6.2.14.0

I hope this is helpful....

ps2000_run_block

OK, my next question. The documentation for ps2000_run_block gives the return values as: Returns 0: if one of the parameters is out of range. 1: if successful. However when I run my unit tests, I am getting back the value of 4 from this method. I find that if I just treat !=0 as OK, then my tests al...

Thanks - I understand that now :-)

I had been thrown of course a little because PicoScope 6 only allows values between 0 and 100% .

Thanks again.

ps2000_set_trigger

I have a query about the ps2000_set_trigger SDK Method. The SDK document describes the 'delay' parameter thus : delay, the delay, as a percentage of the requested number of data points, between the trigger event and the start of the block. It should be in the range -100% to +100%. Thus, 0% means tha...

Licensing etc

Hello, I have a question regarding licensing with the SDK for Pico 2000 range scopes. Specifically, if I develop a commercial product are there any restrictions on using the SDK, and can I use the name 'Pico' and or 'PicoScope' in my product marketing? For example can I say "Remote Scope Viewer work...

I tried it out and we managed to recreate the problem. On of our software engineers has sorted the problem out and it will be out in the next release.

Kind regards
Any news on a fix for this yet?
