Got in the post today from hong kong this little beast , very please with it , good wave form stable and works great my scope is a 10mhz Telequipment, the function generator is set to 10 Mhz, the frequency counter is at 10 Mhz ,shows in picture .00002/ .000.3, it eventually settled at .00000, but more likely to be the old frequency counter catching up, don't know if Dave has torn one of these down, but it works for me off to have a play.
