Re: TC-08 all channels show zeros

Hi mortenx,

This is something that would be better handled by our Help Desk. If you send an email describing the problem to support@picotech.com, we will be able to look into this and if necessary organize a repair of the TC-08 (which looks like the best solution).

Regards,

Gerry

Re: Delayed (Bluetooth) Distortion measurement

Hi Didier, You can use one of our PicoScopes to do this. If the waveforms overlap (i.e. there is a gap no gap between the end of the first and the start of the second) then you can just use a Timebase long enough to capture both waveforms, and then align the 1st waveform with the second using a Math...

Re: Overlay two spectrum measurements

Hi Audio-Creative, You can do this by creating a 'Reference Waveform' out of the 1st captured waveform and then capturing a second waveform (note that you can only create a reference waveform out of the transformed data, not the used display mode, if it is different to the default of 'Magnitude'). B...

Re: Corrections for Windowing functions in FFT calculations

Hi Dan, I apologise for the delay in answering. The reason for the delay is that I had to find time to research, in order to clear up some ambiguities regarding the question you posed. Fundamental FFT maths, simply applied, in general is well documented, but because the FFT is so widely used, with m...

Re: Corrections for Windowing functions in FFT calculations

Sorry Dan,

I didn't manage to get a clear answer completed, so I will definitely deal with it tomorrow.

Re: Problem with digital trigger pattern

Hi sarns, Could you tell us exactly what your Digital probes are connected to (for instance, if it is the legs of a chip on a PCB, what is the output type and signal switching levels for the output pins of the chip). Could you also photograph your connection setup and post the image. Then could you ...

Re: Keeping the connection ON and triggering acquisition

Hi Simon, Could you tell me why you want to keep the connection activated, whether you want to do this in PicoScope 6 or in the SDK API, and what your required sample rate and PicoScope Model are? Assuming that the reason for your question is that you're concerned about missing a trigger, then if yo...

Hi sarns,

Could you post the psdata file as I need to see the actual trigger and data to be able to help you.

Re: Corrections for Windowing functions in FFT calculations

Hi Dan, No problem. I kept meaning to get back to you regarding your earlier question of the values returned by PicoScope 6 when using the Effective Noise Bandwidth so, in all fairness, I haven't been able to help you move forward. I've had a look at this and I will have some time tomorrow to give y...

Re: Measure High Power Devices

Hi Volker, Here is a response from Mark: I will have to check back over my wording of the training video but I was using a lower power amplifier (15dBm) with more limited gain. There are no protections against damage in our software so care does need to be exercised when using the P1dB and swept P1d...

Re: Low freq vibration fft

Hi FortvilleFeeders, I would expect any inter-modulation and harmonics to still be relatively low frequencies so the answer to your question really depends upon how long you have to capture/log data for, and to what accuracy you need to be able to see the results of your capture. You will be limited...

Re: Differential Probe Measurement Error???

Hi endowaudio, As long as there is a return path via ground you can pick up a signal (even without the ground clip connected. there will be a return path back to mains via the picoscope earth, and then back to the DUT via the power supply to it, unless it is running on batteries, and the fact that c...

Re: Picolog 6.1.9 Maths channel sample interval

Hi turbine_logs, No you haven't missed anything, 1 second was the limit of the timing precision of the Math Channels in PicoLog 6.1.9 & 6.1.10, however, this will change in the next release, which is imminent. You are also correct that the amplitude precision could be set individually in PicoScope 5...

Hi RAJIPCE, Our TC-08 data loggers are factory calibrated using an internal test procedure which updates data internally. The only way that you could have a unit re-calibrated to alter the internal information, would be to return the device to our test and repair team at our UK facilities & Global H...
