Some of the "experts" out there could yell out that the Siglent FFT is broken or the user interface is so awkward that Dave couldn't get it right. --- End quote --- This was said after we were able to disprove it here, that something was wrong with the FFT. Let's see what comes out of that corner now. --- End quote --- :popcorn: |

Hi, I would like to ask if other users of this scope (SDS1104X-E, latest FW, no hacks) are also seeing this strange behavior: Input signal is square wave 10Hz, 2Vpp, scope has DC coupling, connected with coax cable, external 50ohm load, 1x mode: If I want to focus on the upper flat part of the signal (change the offset and vertical amplification) like this: I can see ringing of the scope vertical amplifier there. It gets worse with more offset. I double-checked with another scope (RTM3004) and it is quite flat as expected: Cichmen |
