Acoustic Modem Option for Control Module
Gavia AUVs can be fitted with the Teledyne Benthos ATM-900 Acoustic Modem. The ATM-900 Series Acoustic Telemetry Modem is the most advanced, multipath and noise tolerant, modem available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. The modems employ two modulation techniques: phase shift keying (PSK), which provides the highest bit rate, and multiple frequency shift keying (MFSK), which provides reliability in a multipath environment, or when the modems are required to operate in a low signal-to-noise (SNR) environment. The ATM-910 Series can transmit data using PSK modulation for reception by a Gavia Modem Deckbox, but receives data using MFSK modulation only. MFSK modulation is a spread spectrum modulation process that transmits multiple tones simultaneously.

Signal Analyzer
bsw TestSystems & Consulting AG
The simplest way to measure the phase noise is to compare the Device-Under-Test (DUT) to the source of a spectrum analyzer. With the SA set at the same frequency as the OUT, you see the sum of the SA's and DUT's sideband-power spectrum on the SA display. It is a simple and straight forward method well suited for free running VCO's where the SA is easily an order better.You can improve on this method by establishing a Phase Lock (PLL) between the DUT and the Local Oscillator and create a zero-IF or base-band spectrum analyzer system.
