Lotek Wireless Inc SRX600 사용자 설명서

Antennas pick up signals from transmitters and delivers them to the SRX 600 
receiver. A typical configuration of the SRX 600 system can accommodate up to 
eight antennas, which can be monitored one at a time or simultaneously. Antenna 
inputs accept signals from radio antennas and upconverted acoustic sources 
(hydrophones). 

To use more than one antenna the ASP-8 switchbox is needed. Connections 
to the ASP-8 are referred to as Antenna Ports and are associated with specific 
Port Numbers. 

A single antenna can be connected to the front of the SRX 600 receiver. It is 
referred to as AH0.

There are several parameters related to Antennas that need to be set before data 
collection can begin. 

• Add antennas to an antenna group

• Enter Gain values for each antenna 

• Enter Antenna Port numbers for each antenna 

• (optional) Designate radio antenna or hydrophone as a master

• (optional) Assign Frequency or Antenna Priority for the scan cycle

• (optional) Enable Master Antenna Preview

• Set the receiver to use the ASP-8

Antennas can be radio antennas or upconverted hydrophones. Radio antennas 
can be multi-element yagi, H-antennas, underwater antennas or whip antennas. 

Antenna inputs on the ASP-8 can also be used for hydrophones (underwater 
microphones). In order for the SRX 600 to use hydrophones the hydrophone must 
be connected to a UUC (ultrasonic upconverter), which is then connected to an 
antenna port on the receiver’s ASP-8. The UUC converts the hydrophone’s 
acoustic signals to radio signals.
