A x100 analog interpolator circuit for 1 ns to 100 ns (10 MHz) isn't rocket science. See the HP 5335A operations and service manual. Getting 10 ns accuracy isn't supprising. > When I picked up my PRS10 at the factory during the tour I learned that > the 10 MHz oscillator in the PRS10 was an improved version of the SC10. > There's an Allan plot for the PRS10 at: > http://www.thinksrs.com/products/PRS10.htm <- overall PRS10 page > http://www.thinksrs.com/assets/instr/PRS10/PRS10diag2.htm <- Just the plot Do the PRS10 comes with the 5 dollar tour ticket or is it the other way around? :D The PRS10 seems like a good device.
