Video Demo - Verifying LTE device behavior

Test the Link Between LTE Base Stations & User Equipment  

LTE signals are very complex and communications between the base station and the user equipment can be difficult to verify. In a closed loop system, it can be hard to pinpoint where a signal problem originates. The Keysight 89600 VSA software can test the link between the LTE base station and user equipment and the comprehensive set of LTE physical layer tools, along with the 89600 WLA software for wireless link analysis, allow for decoding of higher layer LTE messages. Watch this video to learn more about verifying LTE device behavior.

Fast adjacent channel power ratio (ACPR) measurements with Keysight's N9030A PXA signal analyzer 

Watch as a Keysight engineer makes a measurement using the Keysight PXA signal analyzer's fast ACPR measurement. This video shows how a correctly set up PXA can make a measurement in 10 ms (including data transfer time), while exhibiting better than the specified -81 dBc dynamic range. The PXA's fast ACP mode is optimized for throughput. For the highest dynamic range, the PXA has an integrated bandwidth method, which has nominally better -88 dBc W-CDMA ACLR dynamic range (with noise correction on).

Long Term Evolution (LTE) demonstration of how the master information block and system information blocks can be recovered

LTE Master and System Information Block Recovery 

This is a demonstration of how the master information block and system information blocks can be recovered from the LTE downlink signal using the Keysight 89600 VSA signal analysis software. The construction of the LTE downlink signal is the most complex used so far in the implementation of a cellular system. Making use of the flexibility provided by OFDMA and MIMO, the formats of the downlink and uplink RF signals are defined using a mixture of messages across several layers in the protocol stack, from the DCI to MIB and SIBs. A September 28, 2010 webcast shows in detail how some of the most important messages are built up, and how to verify step by step whether the LTE signal you are dealing with is constructed according to the 3GPP Release 8 standard.
