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 VSE-1100 provides: ∙ One tool to update and replace outdated measurement/analysis equipment, combining everything needed to prepare, deploy, and troubleshoot Remote PHY and/or CATV signals efficiently from the headend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.

Verdict
The clearest difference is update cadence: VIAVILab at every 2 weeks against VSE's every 2 months. VIAVILab also leads on device support (3 vs 1). VSE's advantage is iOS requirement (10.0 vs 15.0). On price, ads and in-app purchases there is nothing between them.
