Testing and Maintaining the Equipment

Testing the Layout

• Spread noise

• Geophone analysis (TBD)

• Pulse

• DC ohms

• DC leakage

• RF health

o Number of retries per unit

o KB/sec ???

o Power deviation (looking for a high Tx power unit)

o Rib throughput acceptable/not

• GPS position/timing QC

These tests should all be repeated at the CSS as communications are established

with deployed nodes. In addition, the following tests should be conducted of the

backhaul communications:

• Backhaul network confirmation (LTU-to-LTU-to-CSS test)

• Backhaul connectivity confirmation (BSU-to-LTU-to-CSS test)

The WRU BISTs can be executed at any time. If run during recording, any tests on

the analog board or geophones will result in zero-ed data for the duration of the

test. This may be desirable if one or more WRUs have reported a problem resulting

in a skip-heal during high-productivity operations (skip-healing or self-healing is

covered in another document). Tests can also be run during a pause in recording,

or be sent to a queue to be automatically executed at the next pause in recording.

Test results are written to the database, and can then be printed or written to a

file, as in the case of delivering daily tests to the Birddog.

Each set of tests will be stored as a parameter set in the tree. The following matrix

illustrates WS’s recommendations for which tests should be run daily and monthly,

and which are parts of continuous system health monitoring

4.2.2 Source Control Tests

Seismic Source’s Universal Encoder (UE) is targeted to be the first source

controller to be fully integrated with the CSS software. It will be connected to the

CSS HW as part of an Ethernet LAN. The WS recording system shall support the

same source types and configurations as the UE, including dynamite, multiple

simultaneous vibrator fleets, and mixed source acquisition. When the shooters

and/or vibrator tech have readied their sources, the Observer will establish radio

contact, issue shooting commands, and investigate the content of the post-fire

message. Test shots should be recorded, and correct timing, geometry, and header

values should be confirmed. Further information on this workflow is found in the

Production section

Vibrator similarity tests demonstrate the relationship between planned the sweep

configured at the recorder and the measured ground force at the vibrator. This can
