Now you can capture live field noise and export it to a wide variety of formats with a bandwidth of 212 MHz. The Gfast Analyzer is a Digital Storage Oscilloscope and Spectrum Analyzer in one portable, high-performance system. Perform Gfast PSD mask verification and measure the TDD inter-symbol gap with one instrument using the software's Gfast PSD and TDD analysis features.
Bring live noise from the field back to the lab for injection into test loops. Prepare crosstalk and impulse files for export to the Model 4902 Universal Noise Generator with this 212 MHz system, capable of transparently capturing high frequency interference. The MATLAB-based interface provides convenient options for range selection, sampling rate, capture length and more. The solution operates in three capture modes for control of recording of time.
The Solution also acts as a real-time, general purpose, portable data acquisition system. This convenient feature can be used during installation and maintenance or for spectrum monitoring and analysis to support documentation and reports on the field environment.
ID-337 Test Automation
Using the 501-Portable (or 501-HD) with the 501-JIG and the 501-Probe-D’s is an ideal solution for automating many tests in ID-337 (the Broadband Forum's Gfast Certification Test Plan). The 501-JIG provides two test tools for ID-337 testing (PSD Test Jig and TIGA Test Jig) while the 501-Probe-D can be used for the ID-337 Timing Tests. With these tools the following tests can be easily integrated into your Automated Test Environment - saving valuable time and money:
