Teledyne 440 - Background Noise Profile Logging Format; Table 6-8: Background Noise Logging Format

6 – Operating Procedure
6-32 © Teledyne TSS DPN 402196 Issue 4.1
NOTES
❐ The Start character is a colon – ASCII 3Ah.
❐ The identifier character can be either upper or lower case. The two have
exactly the same meaning except that a lower case character indicates that
the coil drive is switched off. The letters are “H”: overheating, “O”: coil satura-
tion/overrange, “U”: under threshold and “S”: normal operation.
❐ Altimeter height in cm above the seabed. Note that ‘0’ indicates that altimeter
is not connected. When altimeter is running, reading is padded with zeros to
fill the 4 spaces.
❐ The signal strengths, in micro volts (µV) measured +99999 to -9999. Always
padded with zeros to fill at least four spaces. The sequence of values is Star-
board coil (early), Centre coil (early), Port coil (early) Starboard coil (stand-
ard), Centre coil (standard), Port coil (standard).
6.4.1.3 Background Noise Profile Logging Format
The format of the Background Noise Profile log is specific to this facility. It can only be replayed via the
Background Noise Profile dialog box. Table 7.6 shows the logging format.

NOTES
❐ Timestamp formatted as HH:MM:SS obtained from the controlling PC system
clock.
❐ The Signals Data packet is in the standard internal signals format (see Table
7-5) except for the start character (ASCII 3Ah) and Event Identification char-
acter are comma separated from the following fields.
