Abstract
A downhole system includes a first module having a transmitter that transmits at least one sync control signal. The system also includes a second module having a sync module with a direct digital synthesizer (DDS). The sync module analyzes the at least one sync control signal to identify at least one of a sync frequency and a sync phase. The DDS adjusts a local receiver clock based on the identified at least one of a sync frequency and a sync phase.
Claims21
A system with downhole synchronization, the system comprising:
- a first module having a transmitter that transmits at least one sync control signal;
- and
- a second module having a sync module with a direct digital synthesizer (DDS), wherein the sync module analyzes the at least one sync control signal to identify at least one of a sync frequency and a sync phase, and wherein the DDS adjusts a local receiver clock based on the identified at least one of a sync frequency and a sync phase.
(canceled)
A method with downhole synchronization, the method comprising:
- transmitting at least one sync control signal from a first downhole module to a second downhole module;
- analyzing the at least one sync control signal at the second downhole module to identify at least one of a sync frequency and a sync phase;
- and
- using a direct digital synthesizer (DDS) to adjust a local receiver clock of the second downhole module based on the identified at least one of a sync frequency and a sync phase.
