Product Overview
J2901A is a dual 2-to-8 cross-bar test set. This unit expands VNA ports to any combination. This not only increases the number of ports, but also dramatically reduces the time required for re-routing, re-cabling and re-configuring.

Associated with proper software, J2901A acts as a cross-connect in variety of automated applications. Since it’s flexibility of signal routing capability, the NEXT (near end cross test) become feasible.

With a rigid meta standard 19-inch enclosure, J2901A can be mounted in 19-inch cabinet and/or underneath of a VNA (vector network analyzer) such as Keysight E5071C
lexible Configuration To Expand VNA Ports




Flexible configuration to expand VNA ports to any combination.
Easy access to RF input/output connections from front panel permits easy maintenance and reconfiguration.
With auxiliary ports for VNA to bypass test set to increase flexibility.
Standard calibration method and performance check to allow operator to perform accurate test.
LED indicators display the port routing status
High-performance Switches for RF Applications

High isolation, low insertion loss and high repeatability (please refer to specifications below for details).
Guaranteed 5 million cycles operating life to reduce cost of test.
Smart Counters to Monitor Switching Times

With switching counters, they can be used to count switching times of all coaxial switches.
PC program can monitor these counter value and then trigger alarm as soon as one of them exceeds maximum allowed value.
Agent Port Provide More Methods To Trigger Testing


With optional agent box, testing can be triggered by operator manually.
Or testing can be triggered by barcode scanning to ease DUT management.
Remote control Through RS232

Support RS232 interface for remote control applications.
Provide PC program the ability to control RF signals routing and offer pass/fail test result.
Royalty-free API Library

API can be used to develop customized ATS measurement system or lab test application.
Library includes programming reference, example source codes for VB and VC++.
