What is RF Record and Playback?

Today’s Real-Time Spectrum Analyzers offer capabilities to capture and record RF data vs. time for playback and analysis. This is extremely helpful if you’re trying to find the proverbial “signal needle” in the haystack. This page discusses the solutions available to you, to help you find your signal of interest faster.

Current State for RF Record and Playback Solutions

RF recording and playback system have traditionally involved complicated system of hardware software that was both expensive and cumbersome. As technology has evolved it is now possible to put those large systems into a smaller, easier to use and less expensive package. Rather than being limited by a simple screen shot, engineers now have the ability to accurately record RF signals for long periods of time, and analyze this information in an efficient and timely manner.

Complex analysis of ECM or RADAR systems, capturing RF interference are just some of the applications that are addressed with this simple combination of hardware and software.

 

 

What are the components of a RF Record
and Playback System?

RF record/playback systems fundamentally are composed of three different parts: receiver, storage and analysis/playback.

Receiver: modern real-time spectrum analyzer take advantage of the integrated IQ process
to digitize all of the signals with the real-time span.

Storage: PC’s and laptops can be easily configured to stream recorded IQ directly to disk. You’re then able to define your own capacity based on your application.

Analysis/Playback: ideally, this is the same platform you used to collect your data so you
can avoid spending large amounts of time transferring files. For instance, Tektronix enables
engineers to directly analyze the recorded RF through DataVu-PC software, run on your own
storage device.

 

Tektronix RF Record and Playback Solutions

Recording in the field and analyzing in the lab has never been easier. Depending on your application, Tektronix offers numerous Real-Time Spectrum Analyzers to help you capture
large amounts of data for storage, analysis and playback. Options like the small form and
tactical RSA306B, RSA500 or RSA600 units, offer low cost, high performance, field or lab
use.

The robust capabilities of the benchtop RSA5100 and RSA7100 analyzers, support streaming
at bandwidths up to 800 MHz. Coupled with DataVu-PC and SignalVu-PC, Tektronix offers a simple and straight-forward RF Record and Playback solution.

 

 

Software Analysis for your Complete RF Record and Playback solution—SignalVu-PC vs. DataVu-PC

Tektronix offers complimentary analysis software, SignalVu-PC and DataVu-PC, to
support recording and playback solutions.

DataVu-PC has been specifically designed to search through long recordings to
automatically identify signals of interest based on user input. It has full real-time
playback of captured signals, automatic identification of pulse signal types,
supports exporting IQ to industry standard formats, and supports two-channel
IQ recording as well.

SignalVu-PC is designed to support playback and demodulation of captured
signals. It is a full vector-signal-analysis powerhouse that’s also offers fully
automatic RADAR analysis.
