Before these signals began both broadcast and amateur waves were uncertain and often wavemeters disagreed violently.
The subject of the contract is the delivery of a single-frequency ultra stable auxiliary lasers with small ytterbiove ion drift for hours, including equipment for stabilizing the wavelength of the wavemeter and accurate on-line measurement using a wavemeter.
The laser system should include a wavemeter, frequency doubling module and be compact, stable, have low noise and easy to use.
* Sensors (strain gauges, accelerometers, inclinometers, pressure sensors, wavemeters and wave radars) to detect both environmental conditions (wave period, height and direction) and the structural and operating behaviour of the ship;
The evolution of pulsed frequency measurements started with manual measurements using wavemeters and has evolved into instruments that can automatically profile the frequency with a pulse.
