Re: 4227 External Trigger

Thx Ziko . I had missed it on the specs. So presumably it will detect a TTL level change.

4227 External Trigger

What type of trigger can the EXT input work with on a 4227 ? TTL (0-5V) digitial inputs? analog?
Thx.

ETS Example for LabVIEW

There has been a few posts already asking for ETS LabVIEW examples. I was wondering when this would become available, as I am trying to get ETS running under LabVIEW as well, but the documentation is rather slim on this topics.
Thx.

Re: GetUnitInfo string garbled 4227/4224

What seemed to be the problem was the fact that I am using a LabVIEW ring or enum to pass data to the Info parameter. Even though the ring or enum is set to the right data type, it still creates occasional problem when passing the paramter. If the iteration counter, or a straight number as opposed t...

Kernel Driver install does not work

Hi, I am using a 4227 on XP, SDK r10.1.0.17 . I want to install the kernel driver on my PC but the information is not clear at all. In Picopp folder, USBReadme.txt suggests to copy picopp.inf and picopp.sys in the right place. Under winusb\x86, DPIsnt.exe is supposed to do the install, but after run...

Re: GetUnitInfo string garbled 4227/4224

Hi Chris, The behavior is not consistent. I verified the parameters and they are correct. Of note though, the Info enumerated type expects a U8, not a U16 in the version of the dll I am using. However, there is still a small red dot at the Call Library Function connector in LabVIEW indicating there ...

GetUnitInfo string garbled 4227/4224

Has anyone experienced garbled responses from the driver when GetUnitInfo is called? I am using a 4227, and few month ago a 4224 and the same thing happened, somewhat inconsistently. Part of the strings in the response from the dll call appears garbled with funny characters... This is a problem, as ...

Re: PicoScope 4000 series driver and XP embedded

In this context "embedded" refers to the compartimentized version of the Windows OS.

Respectively, "Windows XP Embedded" (XPe) in relation to Win. XP, and "Windows Embedded Standard" in relation to Win. 7.

Re: Rapid Block Mode LabVIEW PS4224

As per earlier conversation, the LabVIEW example you mention uses multiple API calls. This may be valid but it is not what we want to achieve. It is expected that multiple calls will generate more overhead both in the call and in the data stream resulting in more time for data transmission from the ...

Re: Rapid Block Mode LabVIEW PS4224

The C code uses API calls that are different from the ones in the original LabVIEW example. Do you have a LabVIEW example of Rapid Block Mode?
thx.

Re: Rapid Block Mode LabVIEW PS4224

Hi, I have been trying to speed up the Rapid Block Mode example provided by Pico. In their example, the ps4000GetValueBlock is called for each segment. Since this API call allows for selecting fromSegmentIndex and toSegmentIndex, it seems possible to obtain all the data in a single call instead of c...
