JDSU MSQ-900 Overview
JDSU, home of Wavetek™ field meters, provides a new level of value and performance in a QAM signal level meter (SLM). The MicroStealth QAM SLM is an ideal tool for field technicians seeking a single tool to quickly ensure the quality of digital cable services.
The MSQ-900 is simple and compact, yet packs an impressive feature set with remarkable performance. It provides all the necessary tests for verifying digital and analog cable services up to 1 GHz. The digital measurements include digiCheck digital signal level, modulation error ratio (MER), and pre- and post-FEC bit error ratio (BER). The MSQ-900 also possesses the features expected in a good SLM including analog channel video level, video-to-audio level, carrier-to-noise (C/N), full scan, and tilt.
In addition to verifying digital and analog services, the MSQ-900 can also accomplish its tasks quickly and efficiently. Users can reach all tests with one button press from the main menu, making training an issue of the past. An automated test feature lets users execute a set of user-defined tests with Pass/Fail indication to ensure that tests are performed consistently at each installation without wasting time.
The MSQ-900 addresses the traditionally difficult task of configuring an instrument to perform digital measurements, including MER and BER. The new AutoPlan functionality automatically detects channel type (analog or digital), the QAM type (64, 128, or 256 QAM), symbol rate, Annex (A, B, or C) and spectral inversion. Users only need to select the correct channel plan template and the MSQ will automatically build a channel plan based on the live signals it discovers.
