E NABLING/DISABLING AGC
Enable or Disable AGC via CodeLog > 1)Config## > 2)Scan Settings > 3)Options
> 3)AGC.
AGC stands for Adaptive Gain Control and gives the receiver the ability to
dynamically adjust antenna gain settings to optimize performance. This feature is
particularly useful when there is sporadic external noise, like turbines coming on
once a day at a hydro dam. In cases like these the receiver can automatically
adjust the gain when these noise events occur and then return the gain to its
original set value when the noise event is over.
CRTO cannot be used if AGC is enabled, because gain must be fixed for the
duration of a data record.
E NABLING/DISABLING THE GPS CLOCK
When the receiver begins scanning it can simultaneously update the GPS clock as
long as the GPS clock is enabled. This provides a higher time resolution for data
recorded by the receiver.
When the GPS clock is enabled it comes on for five minutes and updates the clock
every 1 second and then it turns off for three hours. It repeats this cycle
continuously until scanning is stopped. During a scan the display flashes the
letter G to indicate that the GPS clock is enabled.
If the GPS clock is disabled the GPS positioning feature is automatically
disabled.
Enable/disable the GPS clock via CodeLog > 1)Config## > 2)Scan Settings >
3)Options > 4)GPS > 1)En/Dis GPS Clk. The first line in the display shows the
current setting and updates accordingly when 1)En/Dis GPS Clk is selected.
E NABLING/DISABLING GPS POSITIONING
In order for the receiver to acquire a GPS position, the feature must be enabled.
The GPS clock must be enabled for the GPS positioning feature to work.
