D EFINING A FREQUENCY STEP
The frequency step is the increment in kHz that the receiver uses to increase the
frequency as a scan proceeds. Enter the value for the increment via Manual >
2)Search > 1)Start > 5)Freq Step.
Starting a scan via Search means that the Set Delta frequency is not used. For
Search the frequency step option is provided to set a frequency increment.
S ETTING THE SCAN TIME
Enter a time in seconds to specify how long the receiver should scan each
frequency+antenna via Manual > 2)Search > 1)Start > 6)Scan Time.
S ETTING THE NOISE THRESHOLD
The Noise Threshold is a minimum allowable detection signal strength. This
means that if the receiver detects a pulse that has a signal strength equal to or less
than the noise threshold it is rejected and not used for further code processing.
Typically the noise threshold is set to 30, but should be set to reflect the
environment in which a study is taking place.
Set the noise threshold via Manual > 2)Search > 5)Noise Threshold. The
maximum noise threshold value that can be entered is 99.
