Re: TC-08 giving + readings when they should be negative

Hi Thermalman,

It sounds as if there could indeed be a problem with the data logger.

Could you contact our Help Desk at support@picotech.com giving the same details (or referring to this post) so that we can help you further with this issue.

Regards,

Gerry

Re: PicoScope 5444B

Hi Fabrizio, The Scope would be outside of it's operating temperature range, so your measurements would be inaccurate. But, more importantly, it would be outside of it's storage temperature range (for 60°C to 70°C) so you would risk damaging components (over time if not immediately). Regards, Gerry

Re: PicoScope 5444B

Hi Fabrizio,

I'm not sure what you mean by "I would need isolation values ​​of this type". Could you explain what you would need in more detail.

Regards,

Re: Rising Edge Count Problems

Hi Hydramec, Unfortunately there is a limit to the number of edges that can be counted (which is 10,480) so once you go past that there is no total count to show. This appears to be an error which I will pass on to our development team. Having said that, the limit that you are seeing (of 93) is beca...

Re: Error occurred while collecting data and terminated before the scope close, now it will not reconnect

Hi shlakene, This looks like we may need to get the PicoScope returned for examination and test. Could you send us an email at support@picotech.com. In the email could you tell us the following: Could you give us more detail about the error that occurred (e.g. was it a windows error, dll error, codi...

Re: PicoScope 6.14.4 Hang up

Hi AlexBo, This type of issue is very specific to your particular setup, and often a temporary issue. So, it isn't normally very useful to other forum users. If you send a support request to our helpdesk, by emailing us at support@picotech.com, we will be able to respond to you directly and help in ...

Re: USB 1.1 Signal Integrity

Hi pkamgar, Typically, over longer cable lengths you will see a rounding off of the corners on the bit-stream waveform of USB 1.1. There may also be more distortion due to more pickup of Electromagnetic Interference, and more noise. To view the distortion, the product that you will need depends upon...

Re: PicoScope 5444D MSO detailed performance specs? (ENOB / SNR / THD / SINAD / SFDR)

Hi Eric, The 5000 series PicoScopes use multiple ADC's to provide increased sample rates (interleaving ADC's) or increased resolution (stacked ADC's) so for the highest sample rates and resolutions, yes they would be limited by the number of channels (actually the number of channels available is lim...

Re: Measuring small dV signal over 600VDC bias

Hi mechaman1, O.K. now that you've explained your application in more detail, I can see there is no AC usage involved (or phases to consider), just transients. As you're measuring a differential voltage at the relay, to get the precision that you want, you need to be able to reject the 600V DC signa...

Re: Measuring small dV signal over 600VDC bias

Hi mechaman1, First of all the PicoConnect 442 Probe is NOT suitable for your application. The Probes are CAT III not CAT IV . I would suggest searching for a reputable supplier of CAT IV probes on Google. The PicoScope 4444 has a relatively high noise floor so although it will give you an improveme...

Re: Picoscope 6 / DrDAQ and FRA4PicoScope

Hi Phil, Technically you could create your own application using our Software Development kit to sweep the DrDaq, but you will need a PicoScope to use the FRA4Scope. The better specified PicoScopes for audio, will give you test results of a higher, more professional level (so a PicoScope 2204A will ...

The sample rate of the channels shouldn't normally be affected by what channel you trigger from. If you could also explain in mor...

Re: IMD measurement and signal generator

Hi teemumm, The answer to your question is yes. However, you need to use the Arbitrary Waveform Generator to do it. Probably the easiest method would be create the waveforms in Excel over a column length equal to the length of the AWG waveform buffer (4096 for PicoScope 4262), then save them as a CS...
