The SDA Family: Field Unit (SDA-5000)

• Observe noise signals clearly with the built-in pre-amp. Instead of

needing to guess about a signal that is just above the noise floor, the

built-in pre-amp allows you to clearly see and diagnose noise

• Easily see the difference between meter-induced intermodulation and

system intermodulation and CPD (common path distortion). A built-in

low-pass filter strips away higher power forward path signals to examine

just the reverse path

• Save money, connections, and time. Carry just one box with all the tools

needed to find ingress

Pinpoint return path problems by analyzing digital

return path signals at any point in the field

• D/U (desired/undesired) measures signal quality in-service and in-

channel when you’re examining TDMA signals

• See data packet collisions

• View relative transmission levels for all the transmitters present in a

cascade

• See how heavy network traffic is in a given amplifier cascade

• Level measurements allow you to align both TDMA and continuous

digital channels

Align return path amps more quickly and with fewer

errors

• Adjust return path amplifier tilt and gain

• Display injection levels and absolute headend signal levels

• Calculate system gain and tilt automatically

• Reliably measure reverse sweep and level with an improved test point

compensation setup

• Compensate for test point loss in complex two-way amps using

improved, informative displays

The SDA-5000 field meter also offers interoperability with Acterna’s

PathTrak Performance Monitoring System. Interoperability is an exciting

feature that enables you to solve return path ingress problems more

effectively. Node spectrum data received at the PathTrak System can be

broadcast to the field unit, allowing you to compare local (field) spectrum
