Re: Limitations of PicoScope 6?

The default operation for the onboard memory is a segmented circular buffer where you can have up to 1000 waveforms. You can set the number of buffers in Tools->Preferences->General->Maximum Waveforms To get access to the full buffer for a single capture you need to set your trigger mode to single. ...

Re: Visual Studio C++.net

The c example will compile with c++. Considering the API is pure c, there is no real need for a c++ example. You can use the c header in c++.

Re: calling th-03 from c#

I don't believe there is a problem with your import.

Could you put all your driver calls up to this point in a simple console application. If that can reproduce your problem, could you please attach that .cs file to this thread?

Re: USB TC-08 Linux installation

How far did you get with the installation? 1. What is your output from lsusb with your device plugged in 2. Can you get usbtest to work as root (sudo) 3. Can you get the example program to work as root (sudo) 4. Have you installed the .rules file 5. Have you added your user to the group pico (or the...

Try setting the channels to DC rather than AC.

Re: Aliasing problem with 3204 and picoscope 6.2.20?

You might find that it is the DDS that is giving you the results. If the sampling rate of the DDS is a multiple of 5 and 10MHz it can do a perfect squarewave for those frequencies. Any other frequencies (not an integer divider of half the dds sampling frequency) close to the samplingrate will have a...

Re: Single SW Installation for Mutliple Pico Products?

Hi,

You can definitely have PicoScope 5 and 6 installed in parallell.
I suggest installing PicoScope 5 first and then PicoScope 6.

Regards

Re: Single SW Installation for Mutliple Pico Products?

You are correct, it looks like the Dr DAQ is not supported by PicosScope 6. Both prodects should be supported by PicoScope 5 though. I believe the feature "install for other devices" is available for PicoScope 5 as well.

When you install PicoScope6 in the device selection screen.
  • Select your main device in the dropdown list.
  • Tick the checkbox "Install for other devices"

Re: uV level resolution?

When you are comparing ranges and resolution bear in mind that. Our 50 mV range is the same as: 10 mV/div 390 uV/count (with 8 bit resolution, 2000/3000/5000 series) 24.4 uV/count (with 12 bit resolution 3000/4000 series) Our 20 mV range is the same as: 4 mV/div 156 uV/count (with 8 bit resolution, ...

Re: measuring current using PicoScope

You could use two channels, one measuring each side of the resistor. You could then use a math-channel to calculate the difference i.e. the voltage drop across the resistor.
You could also scale the math channel to give you the current rather than the voltage drop.

Re: Picoscope 4424/4000 Series

Hi, I believe some of the functions in the example program might be leftovers from a version for the ps3000,ps5000 range. For example the ps4000 does not have a signal generator so those functions are not available for the ps4000. The trigger point within a capture is set by the noOfPreTriggerSample...

Re: trigger problem

Assuming you have set it up to trigger on a rising edge there is no bug. It is clearly triggering on a rising edge. To trigger on the first rising edge in a burst you need to setup a more advanced trigger criteria. You could try Pulse Width Negative Pulse Greater than 200 us That should trigger on t...

Re: Picoscope 4424/4000 Series

The file which has the information you are looking for is called "ps4000pg.en.pdf".

The functions that setup the trigger include but are not limited to.

ps4000SetTriggerChannelDirections
