Hi,
maybe it has been reported earlier in this thread already but unfortunately I couldn´t find a ´search in this thread´ function.
What I like about my SDG2042X besides it beeing a great generator is that I can use it for curve tracing of small signal transistors
As it offers two channels one can easily and quickly generate the Ramp resp. Staircase waveforms required.
I think it should also be possible to test power devices too in that I take a dc-capable power amplifier to boost the Ramp signal to the required voltage and current levels.
A simple Dual output lab-supply could then power the amp.
The supply is also useful to evaluate the Ic over Vbe curves ... supplying a constant voltage to the transistor´s collector and feeding the basis with a ramp signal.
In any case my old Philips PM3267 draws beautiful curves in a smashin´ GreenLantern green
.... the new SDS2104X-E DSO isn´t as good in that ... as probabely all DSOs.
regards
Calvin
