Re: Triggering and Streaming

In infinite streaming mode you don't use triggers.

Then you do the real-time analyse in your software on the incoming data stream.

Re: Improving PS2 decoding

It looks like your sample rate is too slow. Try increasing the value of the 1 MS as shown below to 10 or 100 MS. Also turn decoding off during the capture, in some situations this will allow for higher sample counts. 2021-06-24_08-15-34.png This one is with the settings you did and resulted in a sam...

Re: Serial Decode UART - Channel B not appearing

Can you post a .psdata file ?

Re: Logic Triggering Using A Threshold and A Level

Can it be the D signal is already low when the A signal gets the negative edge ?

can you post a .psdata file with only trigger on negative edge of A.

Re: PicoScope 7 T&M Early Access program - Introduction

I know you can name them. But there is no name next to the wave as the digital waves have.

Re: PicoScope 7 T&M Early Access program - Introduction

Nice you can mix analog and digital channels looks awesome.

Still missing the channel name for the analog channels, it would be nice if they are displayed the same way as the digital channels.

Will also send feedback about this.

Re: Streaming mode python script for PicoScope 6000a

Ok I see the code is only half done.
Depending on your python skills you can try to convert complete the code from the 6000 example or even the 5000 series.

What I know from C code the overall structure per scope series is the same. Most time some minor differences.

Re: Looking for a different picoscope

As far as I know none of them is above 2V. Depending of hou you want to measure you have 2 options. 1. Use a DC amplifier search on amazon or aliexpress for OPA541 as in image below (this one needs + and - 15V to + and - 30V to operate correctly) 2. Use a external function generator search for JDS66...

Re: Noisy TA189 Current Clamp

if you do a low pass filter e.g. 1khz the signal is far better.

unless you want to measure low current at higher frequency's.

Then it is smart to use a 10 ohm resistor and measure the voltage drop on the resistor.

Re: python PS5444D MSO streaming mode, time discrepancy

I don't have experience with python but it looks like you are sampling at 1MS/sec and you are doing some calculations digital channel splitting in the callback function. I probably step on someone's toes but python is not fast enough to do the splitting and copying you seem to do in the callback. Ca...

Re: 1-Wire Bus decoding issue ?

the signal is probably inverted.

Then you get this kind of mismatch.

Re: Measure large signal with a small measuring range

It helps a lot if you explain what you are trying to measure.

AC or DC.

Voltage and the voltage range you are interested in.

and for safety reasons is it directly connected to mains voltage.

Re: Picoscope 4262 signal generator

This is chineese export so I don't expect a good THD.

If you only need 2V rms (I suspect audio quality control) you can build your own with a low noise opamp.
