Show us your square wave
<< < (103/109) > >>

Hello,

the important sentence I wanted to say was: "Siglent SDG7102A and Siglent SDS7404A is very impressive"

But I wanted to respect the topic of the thread and therefore show a square wave. I spontaneously decided to use the PicoScope 4262 and its generator for this. 

But I think you can also show a square wave of the PicoScope 4262, because it is a special and unique device.

So there is no deeper meaning behind it.

Best regards

OK, thank you!
Note to self: Don't always look for the deeper meaning...  :-DD

Still, I wonder what 16bits are good for, if the signal is completely ironed out by the 70ns rise time of the Picoscope.

A good DSA (Dynamic Signal Analyzer) also has at least 16 bits and its rise time might exceed 1 µs.

A digital audio recorder also has up to 24 bits, even though its rise time is measured in microseconds rather than nanoseconds. ;)

The Pico cannot resolve fast ringing and HF noise, but it can do very accurate measurements within its rated bandwidth. Apart from the sexy topics like telecommunication and networking, most prozesses in the industry are rather slow and easily covered by 5 MHz.

Hello,

the square wave has +-900 mV amplitude and 10 Hz. But look at the noise. It is about 0.5 mVpp at 200 mV/div. That is the special feature of the Picoscope 4262.

If spectrum of your signal is under 5MHz, there is simply no scope that can come even close to Pico 4262..
