That is abut what I have. Recommended. If you have been using a tube-based scope you will kick your self for not buying a new digital one sooner. It is a huge step up. I had been using an old tektronix 1980's vintage analog scope (360D) The mixed signal scope is even better if the equipment you are working on has any kind of computer control. > >> -----Original Message----- >> From: Gene Heskett [mailto:[email protected]] >> Sent: Wednesday, April 18, 2018 12:44 PM >> To: [email protected] >> Subject: Re: [Emc-users] Chinese scopes >> >> On Wednesday 18 April 2018 11:25:46 jeremy youngs wrote: >> >> > Anyone try these?
