Have a look for the Hameg in EEVBlog #842.
The HMO1002 ranges between 50 and 100MHz, while the HMO1202 comes with 100, 200 or 300 MHz.
Maybe this would be a better choice in respect to quality and "bug free" firmware?
I agree. The HMOs are much nicer than GW-Instek,
and better built. If the tiny amount of Rigol bugs are
really unacceptable to you then that's the way I'd go.
YMMV. There's only one real bug left in the Rigols and it may be fixed soon.
Nobody can deny that $400 for 4 channels, 100MHz, serial decoders, etc. is a real bargain. RMS bug or not.
