Guide to the SRX800 Receiver Preliminary
Typically, the noise threshold is set to 30, but ideally it should be set to reflect the
environment in which a study is taking place. Set the noise threshold via:
Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 2)Noise Threshold
The maximum noise threshold value that can be entered is 99.

The minimum Pulse Width filter threshold is defined through the SRX Host, and
is typically set to 2ms. With the filter enabled, pulses with a measured pulse
width less than the pulse width filter (e.g. 2ms) are discarded.
Enable or disable this feature via:
Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 3)Pulse Width > 1)Enable (or) 2)Disable
The display shows the current setting in brackets using the number of the menu
items available. For example, if pulse width filter is disabled, then the number in
brackets is “2”.

This filter applies to codes (sequences of pulses), and it is used to reject codes
whose individual pulses exhibit a large variance. This feature is useful for
detecting code collisions, where two codes with different signal strengths have
overlapped.
The maximum signal strength deviation is 18. Enable or disable this feature via:
Codelog > 1)Config > 5)Filters > 2)Pulse Filter > 4)Signal Strength Dev > 1)Enable (or)
2)Disable
The LCD shows the current setting in brackets using the number of the menu
items available. For example, if signal strength deviation is disabled, then the
number in brackets is 2.
