Re: Measuring potential and current in a three electrode cell

Yes u can do it u just have to add a resistor in series with u cell the resistor should be around the same order as u cell impedance and then use match channels A-B(across cell) and C-D (across resistor) note the instrument do no provide much current out of the generator max current = 2V/50Ohm as it ...

Measurement logging add sample rate to the function

Hi in the lab with different scopes and picoscope 6 i have been using the the CLI interface for remote controlling of the scope doing this in order to use the scope as a data logger with the recorded measurement data that i have been capturing with the csv argument "PicoScope.com /a Measurements.CSV ...

possible memory leak in picoscope 6

Hi i use the Picoscope 6 software around the lab with PS5000 scopes and a picologger1216 i run picoscope6 continues with different measurements running i read out those measurements with the CLI interface "measurement.CSV" to my datalogging programs labview/python programs but i notes that with the ...

Re: Frequency Response Analyzer with Bode Plots

Hi Aaron I got both an 5000D and 5000A version And yes there is a issue with the detection of auxiliary Power for the 5000D but i am not sure if it also goes for the A/B versions as i just updated to newest SDK before i stepped on this issue at home, the A version is at work where i used it in a ...

Semi bug saving more than 8 channels in other format than psdata

Hi I am using a 1216 to record data on more than 8 channels. In picoscope 6 the limit is 8 channels in one plot, and it creates a scope view more with additional channels to be viewed. When saving recordings it saves only the scope view that it selected before pushing the save button -> this is true ...

Re: Possebilities of Pico Scopes

You can get cheap China usb 2.0 isolators been using them to break ground loops but I don't remember how they work with picoscope but yes they are slow for streaming mode I have not seen any usb 3.0 isolators . But the way to go may be to use a ethernet/fiber/WiFi to usb 3.0 hub One could perhaps ...

away to Plot avarage, min, max of a fast 1msec sampled PWM signal

hi I am using my 5000 series scope to do some logging of a PWM signal that vary in amplitude and duty cycle as well as the frequency from 30 Hz and down to 6 Hz the signal has to be sampled every 1 ms where i want to log the average, min and max value of the signal e.g over 10 sec this seems to work ...

Re: Frequency Response Analyzer with Bode Plots

Hello to everyone, I'm preparing the measurement of stability of my SMPS prototype with my 5444D picoscope. The SMPS prototype is connected to my electronic load. The chracteristics of my SMPS prototype are: - input: 220 VAC (connected to the AC main) - output: 24VDC - 10A (240W) other informations ...

Re: Frequency Response Analyzer with Bode Plots

Hello Aeron

Have you heard anything from Pico tech regarding the possible rounding issue in the scope driver ? when using the sigGen function instead of the awg function

Re: Frequency Response Analyzer with Bode Plots

Hey again Aaron
regarding the frequency shift error
did a test using the awg function and found that there is no shift over the 46.xxx KHz

Re: Generator Frequency rounding issue

Hey Again Andrew Yes it is pure sine function ! Today i did a test using the AWG to set a specific frequency. I did the test in picoScope 6 and it looks like no rounding down above the ~46KHz so good :D ! So i did a deep measurement recording of the frequency and calculated the average frequency i ...

Hi Aaron ! I do not have permission to write private messages and there is also some validation delay on my forum posts This is just guessing ! :) As the freq shift do not accrue at the same frequency makes me think this it is not a driver rounding issue But was wondering if the scope do the ...

Generator Frequency rounding issue

Hey i am having an issue with the setting the correct frequency on my scope generator i assume its some rounding issue. Scope: 5442B so what i do: PS5000AB_DDS_FREQUENCY 200e6 signalGeneratorPrecision = PS5000AB_DDS_FREQUENCY/2^32 // this also the lowest frequency that can be set double actualFreq ...
