Re: Trigger on UART pattern?

If you use one of the deep memory oscilloscope then you can collect / decode huge amounts of serial data. The filter command can then be used to search / find any specific data string you are after. For the 2000 series with smaller internal memories this is still possible for slower serial protocols...

Re: Doubt about roll mode in Picoscope 2204A

Hi, The roll mode with the 2204A works a bit differently to the R&S scope as the PicoScope 2204A does not have the limitation of only working on un-triggered signals. It can capture pre-trigger data until a trigger occurs then scroll across the screen. In roll mode the scope uses PC memory to provid...

Re: PicoScope Beta 6.9.5: Duty cycle graphing

Hi,

I just looked at your data file and its difficult to see what edges you want to measure duty cycle between. When you zoom in you have positive spikes of about 200mV followed by negative of up to -1V (see below).

Re: Odd Channel Difference

Hi, Agree this looks odd but it is normal - let me explain. You are on a range which spans from -5V to +5V (a 10V span). The scope is an 8 bit scope which means the ADC can record 256 different levels. 10,000 mV / 256 = 39mV per step. You have zoomed in vertically by a factor of 10 and both traces a...

Re: Using picoScope 6.0 with DCC

Hi,

Try using a longer timebase 10ms/div or longer to capture more data. Also increase the memory depth to much more than the 3k shown.

Which PicoScope do you have?

Re: TC-08 inaccurate reading temperature

Hi,

With no thermocouple plugged in to the channel what temperature does it read?

Are you set to degrees C or F?

Re: To integrate Picoscope into system

Hi, We do provide OEM versions of our products for several customers. Its best to discuss directly with support@picotech.com with a mention of which standard unit is closest to your needs, changes required and volumes. It will be difficult to connect via SPI as this would require significant re-desi...

Re: 6402D persistence mode issue

Hi, I think some of the issue is the timebase you are using 200uS/div x 10 divisions is 2 milliseconds across the screen. If you have 2 milliseconds per screen then (by the laws of physics) you can not have more than 500 updates per second. Try changing to say 1us/div or faster and the number of wav...

Re: Trigger based on "missing encoder pulses"?

Normally you would use a pulse width trigger for this but if the speed of the pulses changes to much that might not be an option. How fast are the pulses? If they are quite slow then try capturing them in streaming mode (>200ms/div by default but you can change this). In this mode when the trace is ...

Re: Performance of Picoscope 4262 does not reach expectation

Hi, Try increasing the number of points in the FFT (in spectrum options with the drop down arrow). Alternatively change the display mode (also in options) to averaged view. Both of these will reduce the noise floor. As for the SFDR it may be the cable - I have seen 5 to 10dB difference when looking ...

Re: Picoscope not delivering to specification??

Hi,

Its a public holiday in the UK today and I do not have a PicoScope 5000 to check with. Sorry for the delay but I will ask someone to check this and reply on Tuesday.
