Remote Language Compatibility (RLC) X-Series Measurement App, Multi-Touch UI N9061EM0E

Technical Overview and Demo Guide

– Emulates the HP/Keysight 856xE/EC and 8566/68 remote programming language

– Reduce ATE system cost with X-Series analyzers

– Run legacy programming codes using newer SCPI-based instruments without code modification

RLC Measurement Application Provides a Migration Path for Legacy ATE Systems  

As some or all of the instruments in your ATE system racks become obsolete, this measurement application will help you minimize disruption to test program sets, while still meeting the required specifications. The RLC measurement application enables you to upgrade your legacy Keysight signal analyzers, traditionally used in ATE systems to the newer X-Series signal analyzers. Keysight’s X-Series signal analyzers offer remote language compatibility (RLC) with the legacy HP/Keysight 856xE/EC spectrum analyzers and the 8566/68 spectrum analyzers. This measurement application provides as many as 164 supported programming commands from 856xE/EC for the most frequently used spectrum analysis functions in ATE systems. Like all other modern signal/spectrum analyzers, the X-Series signal analyzers use SCPI commands for remote programming. Therefore, a bridge between the legacy 856xE/ EC or 8566/68 remote language and the SCPI language that Keysight X-Series uses becomes necessary when migrating the 856xE/EC to the X-Series analyzer in your ATE system. The X-Series RLC application N9061EM0E provides that bridge. It enables an X-Series analyzer to run most customers’ 856xE/EC or 8566/68 programming codes without modification.

X-Series measurement applications  

X-Series measurement applications increase the capability and functionality of Keysight Technologies, Inc. signal analyzers to speed time to insight. They provide essential measurements for specific tasks in general-purpose, cellular communications, wireless connectivity applications, covering established standards or modulation types. Applications are supported on both benchtop and modular, with the only difference being the level of performance achieved by the hardware you select.

X-Series measurement applications can help you:  

– Gain more insight into device performance with intuitive display and graphs for your application. Select from our library of over 25 different measurement applications.

– Ensure that your design meets the latest standard. Updates are made to the X-Series measurement applications as standards evolve.

– Apply the same measurement science across multiple hardware platforms for consistent measurement results over your design cycle from R&D to production.

– Choose the license structure that meets your business needs. We provide a range of license types (node-locked, transportable, floating or USB portable) and license terms (perpetual or time-based).

How the X-Series RLC application works  

Figure 2 shows a simplified working block diagram for the X-Series RLC application, specifically for the N9061EM0E-1FP. The X-Series signal analyzer, using the SCPI commands for remote user interface (RUI), is unable to understand the legacy remote program commands. Likewise, the instrument-specific, legacy remote program will not recognize the responses returned from X-Series signal analyzers in the form of SCPI commands. The N9061EM0E X-Series RLC application provides an emulation process that enables the user’s legacy program and X-Series signal analyzer to understand each other. As shown in the simplified block diagram below, the RLC application installed on the X-Series signal analyzer, emulates the behaviors of the legacy spectrum analyzer (such as the 856xE/EC or 8566/68). As a result, the user’s legacy program considers the X-Series signal analyzer to be a legacy spectrum analyzer and controls the X-Series signal analyzer just the way it did before the migration. It is important to point out that the emulation processes, as shown in the block diagram, are bidirectional. The purpose of an RLC application is to enable the X-Series signal analyzer to emulate the legacy analyzer. Therefore, not only does the RLC application make the X-Series understand the legacy commands for correct implementations, but it also makes the responses from the X-Series signal analyzer, such as measurement results and query results, understandable to the legacy remote program. Depending on use cases, some legacy commands may not technically be possible for the emulation due to the substantial differences in the architecture and implementation between the legacy and X-Series analyzers. In these instances, the legacy commands that can’t be emulated are logged to a command error log. This error log helps users understand which legacy commands are not emulated by the RLC application, and an appropriate workaround may be required.
