## What is VSE?

The VSE-1100 app is designed to be used in conjunction with the Viavi VSE-1100 CATV and spectrum analyzer.
Note: The VSE-1100 app provides limited demonstration capability without being connected to the analyzer.
The VSE-1100 is the CATV industry’s first consolidated digital spectrum video analyzer and noise-troubleshooting platform designed for the challenges of the converged cable access platform (CCAP) and remote PHY evolution. It is not an update to an existing, analog-based platform, but a completely redesigned product and the industry’s first device developed specifically for the digital cable world – and the rise in unicast traffic.
VSE-1100 provides:
∙ One tool to update and replace outdated measurement/analysis equipment, combining everything needed to prepare, deploy, and troubleshoot Remote PHY and/or CATV signals efficiently from the headend through the Hubsite and into the premise in a portable, compact size.
∙ Powerful capabilities not found in a single platform, including spectrum analysis, MPEG analysis, reverse path/upstream analysis, and QAM measurements – all at a fraction of the cost of owning individual testers required to do similar tests.
∙ A device superior to current and legacy tools that are immobile and heavy, provide slower measurement times, and complicated to set up and use.
∙ Ease-of-use regardless of technician capability, providing automatic network scan/detect to minimize setup time and a tablet user interface that is simplicity itself in terms of operation and remote test capabilities.
∙ Fast, innovative upstream test modes that speed troubleshooting to shorten mean time to repair.

### 5/5 — Dan

*2016-05-11*

Easiest to use spectrum analyzer ever. Downstream analysis is fast, MER on every channel and level in just a minute. Depth of MER is better than anything else on market, even with tilt. Getting channel names off of tunnel, makes troubleshooting channel problems a snap. The upstream analyzer is easy to use. Hyper spectrum always sees the noise.

• Total/Span Integrated Power of downstream channels
        o Automatically calculates the power of all the downstream channels being tested
        o Adjusts which channels are included based on those being viewed and tested
        o Measurement available in RapidScan and Performance Scan views
• Test Point Compensation
        o AutomaticallyadjuststhedisplayedlevelsbasedonconfiguredTestPointtemplates
        o Easily select different templates while in each applicable mode
        o Can be applied to both Upstream and Downstream measurements
Other changes made in the v2.5 release:
• Level measurement consistency issue in frequency extension band above 1.1GHz
• Empty Channel Plan label will no longer crash the iPad application
• Better display of CW levels in a wide span when using markers
