Re: detect max interval between flanks

in the example .psdata from the first post

the times below so max low time or max high time.

Re: Pico Scope 6824E C# RunBlock method max nº of samples

Streaming mode will not get you beyond 40MS/sec or somethin like that.

if you are sampling 28 sec at 4G/sec that means you need about 128 GB of ram in the scope.

What are you measuring ?

detect max interval between flanks

I have a bit toggle on the output of a uController and want to know what the longtest time is a Interrupt is keeping the main loop from toggling the output (As measurement worst case scenario) Is there a automatic way to do this. I had high hopes for Measurement "Cycle Time" but the min/max/avg give...

Re: Pico Scope 6824E C# RunBlock method max nº of samples

If you are taking in samples for 28 seconds I will suggest using streaming mode.
For this period the number of samples per second you can capture is higher than using the scope memory.

Re: Vertical resolution discrepancy in Picoscope 6?

It is the scope calibration that causes the difference.

Every scope has some differences when it is fabricated. This is compensated with calibration parameters saved in the eeprom of the scope itself.

Re: Using streaming mode with multiple 4824 scope

you need to use 2 separate threads.

Re: Streaming to external disk

Problem is that the speed of external disk is also USB dependent and depending on the motherboard you use it has to be shared with the picoscope usb data.

Best solution would be internal SSD storage for this.
second best solution would be a eSATA or 1000Mb Ethernet storage.

Re: Problems with the UART decoder

Can you repeat the test with a teensy board.

I f this gives the same result I suspect the internal scope oscillator is about 2.2% off.

According your .psdata the measured baudrate of the signal is 117.7 kbps

Re: Problems with the UART decoder

Now the key question which of the timing is off, the scope or de Arduino. I guess the Arduino. Can you make a .psdata file of something with a exactly known frequency at the highest sampling rate possible with your scope. Be sure you set the number of samples to the max (100MS) as in image below 202...

Re: Is it possible to make the Picoscope software use complete data for math channels and measurements?

I think there is a misunderstanding. The math data is always calculated by the windows PC, but there are 2 situations. 1. live view (the math channel data is calculated and shown from the downsampled data) this is because during live view (in all situations ?) there is only downsampled data send to ...

Re: Problems with the UART decoder

Looking at the data again it could also be 7N1 witch makes more sense.

As of why it is not the default 8N1 needs investigation.

can you try with
Serial.begin(115200,SERIAL_8N1);

Re: GUI Refresh rate depends on Time/Dev in Win10, witch is really annoying if you want to do sub Hz mesurement.

Are you using the scope in streaming mode with this slow timebase ?

Tested this with my 3403D scope and I can not reproduce your problem.
