ion c8935f7adf Sayma: bypass dividers where possible to minimize noise (nb this changes the output skew). 2018-06-12 12:56:04 +01:00
hartytp 7a0140ecb2
Sayma HMC830: update interface and register writes. (#1068) 
* Break the HMC830 init into separate functions for general purpose (but, integer-N) init, setting dividers and checking lock

* Use 1.6mA ICP (which the loop filter was optimized for)

* Go through the data sheet carefully and set all registers to the correct value (e.g. ensure that all settings are correctly optimized for integer-N usage)

* Change divider values (now using 100MHz PFD, which should give lower noise in theory)

SUservo EEM docs 
add documentation to eem.SUServo. Change parameterization of t_rtt to include delays on Sampler, as this seems simpler and more robust to changing RTIO frequencies in the future.

Robert Jördens 87d3ac9d25 suservo: swap transfer function parametrization 
The integrator is now parametrized through its gain and not the PI
corner frequency. The integrator gain limit is given in absolute gain
units and not relative to the proportional gain.
