The UMNA system is the industry’s most competitive S-parameter Test System Solution, with best-of-all Price / Performance Ratio and the most versatile and practical system functionalities.

Ascentest began developing RF Switch Matrix in 2010, and released MPS (Multi Port Switch matrix) in 2011, and Dolphin Multi-port Calibration Algorithm for Full N-Port Testing in 2012, VMNA (Virtual Multi-port Network Analysis system) in 2014.

As Ascentest’s ultimate S-parameter Test System Solution, UMNA system, officially released in May, 2016, not only integrates all the exciting features of previously released MPS / Dolphin / VMNA systems, it also adopts Ascentest’s High-performance Solid-state RF Switch Modules, upgrades Calibration Algorithms, and expands Test Applications, which is why this evolved system is named as “Universal” Multi-port Network Analysis system in both Functionalities & Performances.

Specifically, the UMNA system thoroughly releases the test capabilities of a Two-Port Vector Network Analyzer with an RF Switch Matrix, which enables the system to support High-speed, Highly Accurate, Parallel S-parameter testing on almost all categories of RF components, including the accurate testing of Full N-Port S-parameters (SnP).

The UMNA System has the following outstanding Features:

1、 Frequency Range: 10MHz to 8.5GHz, covering all the frequency bands of NFC/RFID, GPS, 2G/3G/4G, 2.4GHz WiFi/Bluetooth and 5GHz WiFi. (Upgradable to 18GHz.)

2、 Test Port Impedance: 50Ω. (Customizable for 75Ω CATV Applications.)

3、 Optimized RF Switch Matrix built on Ascentest’s terminated SPDT & SP4T RF Switch Modules with exceptional high performance & proven stability, which expands the Two-Port VNA to a versatile Multi-Port Network Analysis System with 8/12/16 Ports.

4、 Upgraded Dolphin Multi-port Calibration Algorithm, with the function of Port Extension and simplified method of Fast Multi-Port Calibration, which are all developed by Ascentest solely with all Intellectual Rights reserved. 

5、 Expanded Test Applications & Functionalities developed upon Ascentest’s proven System Software Platform, with 6 more years of continuous tuning and refining. 

UMNA is ideal for almost all categories of S-parameter testing, except for very few specific applications, such as 4G Basesation Filter/Diplexer Testing, which requires ultra-high dynamic range, while the insertion loss of the RF Switch Matrix reduces the dynamic range of the system.

UMNA system is the ideal test tool for RF Component Production and R&D, thanks to its exceptionally attractive Price / Performance Ratio achieved by thoroughly releasing the test capabilities of a Two-Port Vector Network Analyzer with an RF Switch Matrix. 

And, UMNA system can also be delivered with Customized Hardware & Software Services, such as Production Line Upgrade for Automatic Testing, SPC Data Collection & Analysis, Statistical Report and Electronic Bulletin for Visual Production Management, etc.
