I just purchased a Siglent SDS1104X-E during the amazon prime day flash sale, arrived the next day. And I have till the end of January to return it if there are problems. Thanks to the great advice on eevblog I easily enabled the "oscillation overthruster". Also thanks to Tautech for being available for support questions !!
( now may I purchase the SLA1016 hardware for MSO operation for $150 please
?? )
