Setups

The Stanford Research PRS-10 Rubidium oscillator has a microcontroller which recognizes a number of short commands for set-up, and for reading out the state of the device.   Some of the readout values evolve with time, some are set-up parameters that control the behavior of the unit.
For instance, on 8/2/04, the set of readings is:
