Just wanted to add, their US distributor has one with a custom xtal that claims
even lower phase noise and has provided a plot comparing the two
I see the US distributor says the "custom" unit's phase noise
"improv[es] on an already impressive figure" of the stock unit. But in
reality, even
One thing you can do with a Thunderbolt is to let it settle into to disciplined
equilibrium to 10.000 MHz, check the DAC voltage serring, and then switch
off disciplining and manually control the EFC DAC. This will improve the phase
noise at the expense of frequency drift which may or may

Mike already mentioned he has a Thunderbolt. That product you referenced
only has phase noise measurements down to 100Hz offset, but comparing to
the Thunderbolt phase noise measurements that Tom posted at the link
below, a Thunderbolt running on a good quality linear power supply has
about 20dB
Hi
A more significant issue with the output of the TBolt for direct microwave
multiplication
is the spurs on the output. When multiplied up to > 1 GHz, these are going to
be a major
issue. There are a lot of conventional techniques for taking care of this. If
you have not

Hello, Time-Nutters--
Just shipped out three new systems for $DAY_JOB to Goldstone, Madrid and
Canberra.
Love it when work and time nuts intersect.
