S7980A Record and Playback

Wideband streaming solution

Introduction

Modern RF systems are in a rapid state of change.  Wireless designers need a comprehensive assessment of the signal environments that will stress their designs to assure they survive in target markets. The new Keysight S7980A Record solution enables quality recording of live signal environments, in-depth analysis, and high-fidelity RF playback all in one convenient, transportable chassis. The intuitive software guides the user through a structured workflow that turns a complex process into an easy setup and execution. You can quickly and easily record long signal duration files, preview the data, select the portions of interest, and play them back in RF creating a signal environment or high-quality test scenario.  Additionally, you can export files to the 89601200C Vector Signal Analysis software or N6820VRXE Virtual Receiver search and classification software.

The S7980A includes a FieldFox model B which operates as a microwave downconverter with 120 MHz of acquisition bandwidth for frequencies as low as VLF up through 5G NR FR2. Alternatively, a different downconverter can be configured in the system.  Playback is accomplished with the M9383A vector signal analyzer which provides up to 400 MHz of streaming RF bandwidth.  The heart of the hardware system is a combination of PXIe components that form an end-to-end streaming, gap-free RF record, and playback system.  For work at frequencies below 2 GHz, the M9203A ADC input offers recording bandwidths up to 320 MHz via a tunable DDC.

Whether your work is on the bench, in a test chamber, or in the field, the S7980A Record and Playback solution delivers an accurate representation of your signal environment to accelerate your test processes.

Solution Descriptions

S7980A-020

The S7980A-020 includes an N9938B FieldFox analyzer as a microwave downconverter extending the frequency range to 26.5 GHz.  The FieldFox includes Type-N input/output connectors, an AC/DC adaptercharger, a localized power cord, a rechargeable Li-ion battery, a LAN cable, a soft carrying case with backpack and shoulder straps, and a Quick Reference Guide.  Configuration of the N9938B includes the following options:

• B10 Adds 120 MHz instantaneous bandwidth

• 235 Adds wideband pre-amplifier

• 350 Adds Real-time spectrum analyzer mode

The S7980A-020 also has an IF/baseband wideband record sub-system and M9383A vector signal generator integrated into an M9019A PXIe 10-slot Gen 3 chassis which delivers flexibility, compatibility, and performance in a compact form-factor ideal for a range of applications.  It has 18 PXIe slots providing the flexibility to mix and match the number and location of PXIe and hybrid-compatible modules. The ultra-high performance PCIe® switch fabric can operate up to Gen 3 providing up to 24 GB/s of system data bandwidth needed for the S7980A’s high bandwidth streaming feature. The cooling design provides exceptional per-slot cooling while producing much less fan noise.
