Wideband Streaming Solutions, Recording Solutions S7960A-002, -020, and -044

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 S7960A Record solution enables quality recording of live signal environments and in-depth analysis in a convenient, transportable package. 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, and select the portions of interest. Additionally, you can export files to the 89601200C Vector Signal Analysis software or N6820VRXE Virtual Receiver search and classification software.

The FieldFox model B operates as a microwave downconverter with 120 MHz of instantaneous bandwidth for frequencies as low as VLF up through 5G NR FR2. The heart of the hardware system is a combination of PXIe components that form an IF (or baseband) streaming record 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 S7960A Record solution accurately represents your signal environment to accelerate your test processes. 

RF/µW Recording Solutions

The S7960A wideband RF/µW recording solution provides users with intuitive software for configuration, setup, signal preview, and file management. This combination of well-integrated instruments, conversion utilities, and easy-to-use workflow make the S7960A Record solution a valuable tool for a wide variety of recording applications.

Solution descriptions

S7960A-002

The S7960A-002 is an IF/baseband wideband recorder integrated into an M9010A PXIe 10-slot Gen 3 chassis which delivers flexibility, compatibility, and performance in a smaller form-factor ideal for a range of applications. It has 8 PXIe hybrid slots providing 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 S7960A’s high bandwidth streaming feature. The new cooling design provides exceptional per-slot cooling while producing much less fan noise.  The S7960A-002 includes these modules:

• A pre-configured M9203A analog-to-digital converter module with the CB2 bundle is provided that includes the options described below.  This bundle provides a guaranteed recording specification of up to 320 MHz bandwidth, with tunable intermediate frequency.  It also includes data throughput optimization (I/Q samples with 32-bit, 16-bit, or 12-bit mode).  Refer to the M9203A technical data sheet for more details. 

   o SR2: 1.6 GSa/second sampling rate 

   o F10: Full bandwidth

   o M40: 4 GB acquisition memory 

   o DDC: Digital downconverter that provides a tunable IF frequency
