Thanks for the review, very interessing. Do you plan to make a teardown ?

HATE those stupid artistic keypads. They should just stop this nonsense. And as the smallest fonts known to man on a GIANT screen. Keysight is EXPENSIVE but they really have the user interface down. 👍
The only appeal to me with Rigol's new USB powered line is if I wanted to set up a mobile lab, which would be kinda cool!

heyy voltlog

on the eleshop specs page
it says it has arb waveform function

however in your review was saying no arb?

also because there is a bit 50mhz version
and that one says includes arb too

then the 900 series (even more expensive)
also says it has arb listed

so perhaps on the lowest models the specs sheet is wrong?
for example if they copy pasted it from another literature



here is another question missing feature
if we can link any of these models to the 804 oscilloscope

that the does not have built in signal generator
to unlock those extra disabled functions (such as fft sweep etc)

because that is what they do on the siglent
that there is a connection between as external driving device

anyhow hope you are doing well voltlog
nice to see you

Got one and yes it is a very nice device for the money. It looks big on video but in reality it is tiny with a big screen. The noise from the fan is horrible, so loud, nearly unacceptable. The keyboard layout is ugly but I found myself never using it so it doesn't really bother. The remote control works well. It's a pity that they did not succeed in implementing a decent AWG, early versions had it but it is not working well. As mentioned in the video all models can very easily be 'enhanced' to the highest of the 900pro models.

The fan is thermally controlled but they screwed up the circuit to power it. Better off just replacing the fan with a quieter one.

625MS/s but only 25Mhz bandwidth? what a waste.
at least you could program a arb sine with multiple cycles into it to multiply the set frequency.
this way i doubled my FY6800 cheapo from 60 to 120mhz (realistically up to 100..110mhz).
it only has 250MS/s so only a sine at that frequency but its enough to modulate a tone onto it for fm radio reception.
