Are these easily calibrated? I contacted Wavecrest earlier today and they want $750 for the annual calibration. Not exactly 'hobby' friendly :-)

There are two on ebay now, $600 and $700... Buy it now.. I would ask the seller to connect the 100MHz ref output to both inputs one at a time and to measure jitter to make sure they work before buying though.. Dts-2075 recommended due to higher performance. On Oct 2, 2012, at 5:49, Azelio Boriani <[email protected]> wrote: > Wavecrest DTS for $600?
