Re: ps4824 different timebase/downsampling for each channel

Hi agry, Unfortunately, our PicoScopes only have one sample clock and clock divider for all channels, so you would have to just use the fastest sample rate required by any one of your sensors as the sample rate for all of them. It would mean that you would have less available buffer memory for sampl...

Re: Subtracting Average Spectrum

Hi Richard, Thanks for your detailed feedback on a non-established potential application area for our PicoScopes. We are always interested in new and interesting ways of using our products and welcome informative constructive feedback. Currently we only plot a 'Linear' Spectrum that has had coherent...

Re: Custom EMF probe frequency response calibration

Hi Darko, You can use the low pass filter in the custom probe to roll-off from 1Hz (as you need a low pas roll-off of 20dB/decade and the filter in the custom probe is a 1-pole low pass filter). However the custom probe wouldn't be able to give you a resonant peak to counteract the notch in the freq...

Re: Subtracting Average Spectrum

Hi Richard,

Could you just explain your reason for needing to see the actual process of the waveform being averaged over time?

Re: Multiple Pico use

Hi Forda,

Unfortunately, what you require can't be done.

PicoLog 1000 data loggers can't collect their own data. They need to be controlled by the software that they were designed for, which is PicoLog (which only runs on a computer, not on the data logger).

Regards,

Re: How to install picoscope on Macbook

Hi kaito, Yes it is possible, but be aware that, for the current Mac version of PicoScope 6, not all of the functions available in the Windows version have been implemented in the Mac version. To install and run the Mac version you just need to download and install mono https://www.mono-project.com/...

Re: Low signal level in Spectrum option

Hi STMN,

The answer to your question depends upon what you are trying to achieve with your measurement. So, what exactly are you hoping to see from your measurement?

Re: Start Trigger and Timer PicoScope Software

Hi Wilfred, What you are describing is a rising edge Trigger on channel A, which you can set by changing the Trigger Mode (the drop down window to the right of 'Trigger' at the bottom left of the screen) to 'Single' or 'Repeat' (depending upon whether you want to capture one waveform or many), then ...

Re: Low signal level in Spectrum option

Hi STMN, The answer to your question is because the time domain signal that you are looking at has frequency components spread out across the spectrum (which you can see in the Zoom overview). If you were to add up all of the frequency components, in the correct phase, then they would total to 170mV...

Re: Temperature measurement under strong electromagnetic fields

Hi avillegas, Unfortunately we have no off-the-shelf solution, for your specific application, but we do have a partial solutions that you could add required components to. So, in order to retain the accuracy by minimizing the effects of the high electromagnetic field you would need to use a method d...

Re: whatever SNR value you want without changing the signal

Hi Mathius, Just for clarification our specification of noise for the PicoScope 4444, where we quote <180uVrms, on the ±10mV range, this represents a noise ratio to the full scale range of 180*10^(-6)/7.07*10^(-3)= 0.02546, or 31.88dBc. So for a signal at say -1dBc that would be an SNR of 30.88dBc ,...

Re: RS485 (Differential) Hookup

Hi Neil, Modbus RTU can use RS485 (or now EIA485) or RS232, which use different physical connections, i.e. single ended and differential. So, the Serial Decoding provides connections for RS232, and lets you decide how to hook up the differential RS485. So your options are: 1/ Create a Math channel o...
