Battery operated mobile signal level meter DSA500

(Click to enlarge)

DSA500 is a compact, enhanced digita signal analyzer for CATV constructions.
We have accomplished a long-awaited affordable digital analyzer with OFDM/QAM level and BER/MER value measuring capability.
For the convenience of in-house CATV construction, DSA500 achieved extra light weight (only 400g) and easy-to-use, simple functions. It reacts quickly and provides stress-free on-site operation.

Product Overview

DSA500 is designed to measure and analyze all downstream video signals. CATV downstream signals includes: OFDM terrestrial broadcasting signals, 64/256 QAM modulated signals, analog UHF/VHF broadcasting signals 70MHz ~ 800MHz. It measures signal strength, CN value, MER value, BER value of above signals instantly.

Channels and frequencies/modulations can be configured according to the customres' needs as well as downloaded from the Internet service.
The measurement results can be transferred to PCs so you can analyze according to your needs.

DSA500 operates with compact, light-weight batteries (sold separately) and comes with soft carrying case.

When attaching an upstream signal module DSA-ULC (sold separately), DSA500 can measure signal strength of 10~50 MHz signals.
