If unlocking wouldn't work anymore, the current WaveSurfer 4000 HD "fully loaded" promotion is very very tempting. Half the max. BW, but 12 bits and actually more functions out of the box compared to Siglent
Hacking an 7800€ (entry-price)scope...seriously?
Comparing the datasheets, the wavesurfer 4000 hd lost against the 6000A in nearly every case.
Bandwith, samplerate, memory, math-channels, FFT and so on.
And what the promo concerns, take it with caution.
It "says", 61% discount on the package.
On the option-package or on the package scope+options?
To compare prices, you´ll have to take the 4054HD as it got the bandwith the entry scope of the 6000A series got.
Price for the 4054HD on distrelec for example is near on 11000€ without any options.
The 6000A 500Mhz costs nearly 7800€.
