Re: Current measurement

Hi Gustav, Could you let us know which PicoScope you have and what is the max current you want to be able to measure from the battery. To give a quick example using the 1 ohm resistor - lets assume you can cope with a 200mV drop across the resistor at peak current then thats 200mA. I would suggest y...

Re: How to measure the rise time? Results are emty.

To measure rise time accurately there need to be several samples on the rising edge of the square wave. As its a vertical edge there may not be enough samples - try using a shorter timebase so there are less square waves / edges on the screen. This should increase the number of samples used to make ...

Re: frequency measurement resolution

Hi,

Try the DeepMeasure feature - it displays to more significant digits.

Re: Measure LFXO precisely

Hi. As you have a PicoScope 5000 you have access to the DeepMeasure feature in the lastest software. This will give higher resolution / more digits for your frequency measurement. https://www.picotech.com/library/oscilloscopes/deepmeasure Your PicoScope 5444B has a timebase accuracy of ±2 ppm (±1 pp...

Re: Cannot capture signal using trigger

Hi, A couple of suggestions - first check with no trigger that when you measure across the 9V battery the line on the scope trace jumps from 0V to 9V (just in case there is a duff lead or odd setting on the scope). I suggest you set the timebase to say 500ms/div and you should be able to see the lin...

Re: Human heartbeat example for 4444 ?

Hi, The human heartbeat is a small signal to pickup in a noisy environment. Can I suggest you try to make sure there are no mains cables near your body, try running the laptop of batteries and perhaps switch off any lights near you. Proper medical ECG machines tend to use 3 electrodes - one of which...

Re: Noice level of 2206B MSO

Hi, The noise level from the PicoScope 2206B data sheet says that the noise is < 220 μV RMS (±20 mV range) From your capture it looks as if you are on the ±200 mV range and have zoomed in vertically. As you use higher voltage ranges the noise will increase to move than the 220uV RMS figure but will ...

Re: sample between buffers

Rather than collect 32 short buffers (eg of 1ms/div) try collecting one longer one (eg 20ms/div). You can then zoom in and see all the detail in one continuous block.

Re: download location of picoscope 6.7.2 beta software ps520

Hi,

Can I ask why you are trying to use such an old beta - current releases are R6.12 available free for your device from the download option at the top of each page.

If you have a specific reason to need an old release then I suggest you email support.

Regards
Alan

Re: 3205D MSO: Capable of decoding OABR (BroadR-Reach)

Hi, Yes the 3205D is fast enough to capture / display BroadR-Reach. We do not yet have decoder for this but add new decoders for free regularly (We just added CAN FD in the last week or so). I will add this as another request for the protocol which helps move it up the list but can not make any prom...

Re: CAN FD decoder for non automotive 2000 series

Just to add a bit more info to the reply from Hitesh. CAN FD is one of the decoders we are working on at the moment. It may be a few months however before it makes it into a full release. When it does it will be available for all PicoScope users free of charge. If any customers are using CAN FD at t...

Re: Extremely high CPU usage in PicoScope 6.11.13.2

Hi, Firstly PCs and Macs report CPU use differently - if you run a quad core CPU flat out a PC will report 100% whilst a Mac will report 400%. Running in demo mode always uses more CPU resources than running with a PicoScope attached as the PC has to generate the waveform as well as display it. Whet...

Re: Waveform display is very slow, getting data is very slow

Please can you try collecting and displaying a similar amount of data in PicoScope software with the same trigger conditions / AWG settings. If PicoScope is working normally then we can rule out any hardware or driver issues and the problem seems likely to be in the code you have written. We will ne...
