Re: "PicoScope 7 Automotive Beta: Open To All" ?

Got it - thanks! That post was put there as we were getting quite a few T&M customers asking if / when they could use PicoScope 7. The post does explain it is a beta at the moment, missing features and only works with automotive scopes. I agree the "Open to all" graphic is misleading and I can see h...

Re: "PicoScope 7 Automotive Beta: Open To All" ?

Hi Nurber, PicoScope 7 is for automotive users / scopes only at the moment. Where on the T&M web site (picotech.com) does it say its open to all? We may have made a mistake as it should only be on picoauto.com). Thanks!

Re: Attenuators in series?

You should not try to cascade two TA197 10:1 attenuators for 2 reasons. The first is safety - the attenuator is rated at 400V max. Using 2 in series does not increase the safe working voltage - it is still 400V. The second reason is that you will not get the right attenuation - the TA197 is designed...

Re: picoscope file format

The best option is to save as a matlab file - this is binary and the file format is published.
PicoScope file format changes over time as we add new features so is complex / not publicly documented.

Re: Any plans for dark theme ?

All the colors (traces, backgrounds, grids) can be changed to suit. Its a bit hidden so easy to miss - try Tools / Preferences / Colors. You have to change each setting individually so agree a dark theme would be a good idea.

Re: did i make a HUGE bummer?

Hi,

Dont worry if the unit is new we will sort things out with you. I suggest you email sales@picotech.com with details of when and from who you purchased the 4444 and they can advise the best way of swapping it for a 4425.

Include a link in the email to this thread on the forum.

Regards
Alan

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.
