Re: Picoscope not delivering to specification??

Hi, The 5244B has a maximum sampling rate of 1 GS/s and 512 MS buffer memory. This is shared between the channels so with both channels enabled you have 500 MS/s per channel and 256 MS buffer memory. Its not possible to sample at the full speed for 5 seconds since 500 million samples per second x 2 ...

Re: Thermocouple Data Logger TC-08 - Input Channel Isolation

Hi, Just to add to this, the inputs are differential with a 7.5V common mode voltage. To put this another way as long as there is no more than ±7.5V between the thermocouples you will be OK. As you mention they are connected to the same pipe it seems unlikely there would be more than a few mV voltag...

Re: Averaging spectrum waveforms

Hi,

When you enable spectrum mode there is a spectrum options icon (top left, next to the icon for the spectrum). Select this and change the display mode from magnitude to average.

If that does not work for you - let us know.

Best Regards
Alan

Re: 4000 series and PicoLog

Hi Simonis,

Can I ask what it is you need to do that can not be done from PicoScope (which can record millions of samples over many hours).

Thx

Re: feature request: tracking rulers

Hi,

To enable tracking rulers drag the 2 rulers onto the screen. A box pops up to show the time (or amplitude) of each ruler. On the right hand side of this is a small padlock symbol. Click to lock the rulers.

I hope that does what you want, if not please let us know!

Re: Choosing the correct scope

I assume you are talking about valve audio amplifiers? If so that means your frequency requirements are easy to solve as you only need a few kHz of bandwidth when all modern scopes offer many MHz. The main issue will be safety - do you know what the maximum voltage you will be measuring? Most scopes...

Re: Frequency, what is wrong? PICO TC-08

Hi, Is the furnace an electric/arc type? If so I have come across situations where the EMF generated in the thermocouples exceeds the common mode voltage range of the TC-08. In other cases the thermocouple tips are in electrical contact with the furnance but due to the high currents flowing the grou...

Re: PicoScope Beta 6.9.5: Improved waveform update rate

Our team of very talented engineers have continued to work on improving the max number of waveforms per second.

R6.10 beta available from http://labs.picotech.com/ increases the maximum number of waveforms per second as high as 100,000 for our USB3.0 connected oscilloscopes!

Re: How to control vertical range of Spectral Mode?

As its just off the screen try dragging up the left hand axis with the mouse to reveal more. Another option is to click on the x1 icon at the bottom left, from this you can set a zoom of say 0.9 to reveal more.

If that does not work, let us know and we will find another solution.

PicoScope 6: Improved waveform update rate

In a recent forum post http://www.picotech.com/support/topic13697.html we explained how our oscilloscopes maintain a fast waveform update rate even with very deep memory enabled. They can process and display more samples per second than any other oscilloscope on the market. As well as fast waveform ...

Re: The USB bottleneck myth debunked

Hi EPAIII, The raw data / samples are always stored in the oscilloscope. If we sample at 5 GS/s with a timebase of 2ms/div (20 ms total) then 100 million samples will be stored in the scope. As described above the scope uses the hardware acceleration to quickly form and transfer the image to be disp...
