Re: 5444D - Increasing delay in streaming

You can't guarantee to receive blocks of samples at fixed intervals, however you can guarantee that all samples will have been collected at the correct sampling interval on the device. This is due to the buffering mechanism on the device and the transfer process from the device over the USB bus to t...

Re: Zoom resolution problem

If the scope is still actively collecting and waiting for the next trigger it is not possible to zoom in and then download the necessary data from the scopes internal buffer to display the trace in detail. If you press the stop button you should find that the zoomed data appears in full detail.

Re: 5444D - Increasing delay in streaming

The PicoScope 5444D can stream at up to 125 MS/s (8-bit) or 62.5 MS/s (12 to 16 bit modes) shared between active channels so I don't believe there is an issue with the device. The problem is likely to be with the way you are handling the data when reading it from the driver and into your application...

Re: picoscope 2204a

We do not recommend using the 2204a for Automotive Diagnostics and for this reason it will not work with our Automotive or Diagnostic software, and will not give you access to the Waveform Library. It is only 8 bit compared with 12 bit for the automotive scopes so you see signals in less detail. It ...

Re: Measuring current and voltage using PicoLog 1000

Putting a resistor in the ground return path in this way this means you can't select a value to give access to the full 2.5V input range of the logger as this would raise the ground potential on your device by 2.5V (not good). It needs to be a small value resistor to give a minimal voltage drop but ...

Re: Measuring current and voltage using PicoLog 1000

Using the bennog modification to the circuit fit the resistor in position R4 on the terminal board to measure the current in Ch2. However this will cause the ground level on your device to rise, V = I*R so the resistor needs to be small enough so as not to cause a problem, but big enough so the volt...

Re: inductive impedance speaker measuring

Can you post a psdata file of the data you have collected, some pictures and/or sketch of your setup so we can see what you are connecting where, and a description of the results you would expect to see.

You can do this here or send the details to support@picotech.com

Re: 2205A no DC

Does this happen on both channels ? Do you here a relay click when you switch between DC and AC coupling, or when you switch from high range to low range ? It's possible that there is a hardware fault that is leaving the DC blocking capacitor switched in circuit. I would suggest emailing support@pic...

Re: Best practices for using a large number of scopes

Would you want to use the PicoScope 6 software ? or would you be writing your own application to control all the devices ?
