    Ragazzi, non raccontiamo storie. Il manuale in inglese c'è eccome. Lo strumento funziona benissimo. Io in laboratorio ho un Tektronix serie 7000 quattro canali 100MHz che pesa 14 kg, e devo dire che questo l'ho comprato per curiosità. Ma per me è un buon oggetto. Certo che non è portatile, bastava leggere il manuale reperibile in rete...

    ottimo compromesso prezzo prestazioni probabilmente ne acquisterò altri, non gli manca nulla anche per l'utilizzo professionale. Lo consiglierei come strumento base.

    Pensavo fosse portatile invece è da stazione fissa, è un bello strumento, peccato che non ha il manuale in italiano e tutte le scritte sui comandi siano in cinese ... sul web non si trova nulla e i programmi per l'uso con il pc siano incompatibili con win10
