Cellular test solutions leader drives the wireless future using XJTAG
“ To maximise quality and shorten time to market for test equipment supporting the fast-evolving 3GPP-LTE
standards for IP-based mobile services, Signalion GmbH uses XJTAG for testing complex FPGA-based
boards. XJTAG’s powerful features, speed and ease of use are also helping the company focus more
resources on product development.
                                                     ”
