Re: 'PICO_INVALID_HANDLE'

Hi,
Could you give some more details about your setup.
What model PicoScope do you have?
What OS are you using Windows 10/11, Linux?
Python version?
USB connection USB2 or USB3?

Re: Picoscope 2205A and Manjaro Linux in 2024?

Hi, Ok I had little look at this, and this what I found- Fist tested by installing Picolog 6 which is a Appimage. This worked and could connect to the scope! Good! Back to PicoScope 7- The open Picoscope 7 device box seems to detect my 3206D as a "3000A series"? but fails to connect. Going to termin...

Re: Low frequency rms measurement

The rms value of all the cycles in a waveform buffer can be calulated with the maths channel- (sqrt(integral(A^2)/T)+freq(A)-freq(A)) If a trigger is used it must be at the start of the waveform buffer. Crest factor is the peak amplitude of the waveform divided by the RMS value of the waveform. Cres...

Re: DCDC measurement for phase jitter

Hi, I would use persistence mode with manual time rulers, to get your measurement.

Hi, Able to save the psdata file and post here or email support@picotech.com The only spec is- "Trigger sensitivity (analog channels) - Digital triggering provides 1 LSB accuracy up to full bandwidth of scope" Triggering is done digitally and will related to Hysteresis setting for the trigger.

Re: CSV export calls logic signals as Voltage

Hi,
Yes this looks to be an issue in PicoScope 7, I will raise it as bug.

PicoScope 6 export looks like this-

Time,Channel A,D2,D5
(ms),(mV),(Binary),(Binary)

0.00000000,-1.33858300,0,0
0.00005600,-0.39370070,0,0

Re: What exactly does timeIndisposedMs do?

Hi, Instead of using a callback function to know if a block/rapid block capture has finished you can poll the device using psXXXXIsReady(). With programming languages that don't support our C style callbacks like MATLAB, LABVIEW you have to use the polling option. timeIndisposedMs from the psXXXXRun...

Re: Documentation error in ps2000aApi.h

Hi,
The enums are correct the comments are incorrect! So this won't affect any code.
I have reported the bug to our development department.

If this is just happening one PC then try deleting the Appdata folder for PIcoScope 7, this sometime can cause issues- Close PicoScope 7 Paste- C:\Users\%USERNAME%\AppData\Local\Pico Technology Into the address bar of the File Explorer %USERNAME% should resolve to your Windows user account.

Re: grouping graph displays

Hi, Yes you can only have max. of 4 graphs at a time. Unfortunately there no shortcut to organise the channels into views. What Pico device(s) are you using with PicoLog 6? With the SDK you are not able to control the PicoLog 6 software, only the device itself. I could request a new feature be added...

Re: PS 2205A MSO Triggering Individual Digital Channels Using C#

Hi Rob, You should call the trigger functions after you have setup your channels (SetChannel(), SetDigitalPort()) If you are just setting up digital channels for trigging you only need to call- ps2000aSetTriggerChannelConditions() and ps2000aSetTriggerDigitalPortProperties() Note in streaming mode y...

Re: Picoscope 6404E data acuisition and visualization

I assume you are using a FFT function in LabVIEW to generate a FFT plot?
To get a stable waveform you would need to enable the trigger with a block or rapid block capture.
