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 ...

Re: Trigger on EXT port

Hi haziqsahaja, Could you tell us exactly which model 3000 and 5000 PicoScopes you have, and could you post your psdata file so that we can see how you have thing set up. 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...

Hi Vinnavan,

Can you describe your problem in more detail, and post a psdata file so that we can see what you are doing.

Re: phase noise measurements

No problem. Let us know if you find that that is not the case. We certainly don't have all the bases covered in our products, so we welcome your points of view, and there are always interesting twists on measurement applications that give us an opportunity to adapt what we have, or encourage other u...

Re: Waveform capture rate

Hi Azibitsker, If you are (a) using a fast enough TimeBase (10ms or less), and (b) not completely filling the waveform buffer of the 6404C when you capture each waveform, then you can split the waveform buffer and use 'Rapid Trigger Mode' in PicoScope 6 (or Fast Block Mode in the SDK). This can give...

Re: Trigger on interval between 2 channels

Hi Benno, If I understand you correctly, what you need is 2 channel logic triggering with timing, which we don't have in a PicoScope, so you would need some hardware to implement this. You could implement it with a watchdog timer function, i.e. Ch C starts a counter/timer, and Ch D stops the Timer, ...

Re: Measure High Power Devices

Hi Volker, Sorry for the delay in responding (I have been out of the office). The P1dB sweep of power and frequency is indeed a single sweep plan of the whole test space. The whole plan runs on the hardware and is not uninterruptible until it completes. This would include closure of the P1dB window....

Re: Project - Machine Downtime

Hi watson118, What you appear to need is a watchdog timer application. So, when (and only when) the timer times-out, the logged level goes to zero. You can do this fairly easily using our Software Development Kit (SDK), and a time delay function (e.g. set to 1 second) used to create a pseudo watchdo...
