Oscilloscope and instrumentation vendor Tektronix Inc. is releasing its RSAVu offline analysis software. With RSAVu, you can acquire signals using a Tektronix real-time spectrum analyzer (RSA) and then examine the captured information offline on your PC. The PC will need to run a Pentium-compatible microprocessor and have at least 75Mbytes of free hard-disk space. While the analysis functions of RSAVu are identical to that provided with Tek's RSA3300A, RSA3408A and WCA200A real-time spectrum analyzers shown above (you must have one of these instruments to acquire signals for transfer to RSAVu).

Peer into digital RF
Tek's RSAs are designed to help you work with digital RF. Applications include analysis of software defined radios that use complex modulation techniques, radar with its time-varying and pulsed RF signals, and RFID that makes use of momentary communication links.

The PC-based RSAVu software can provide the same analysis capabilities as exist on an RSA. You'll be able to capture files on one RSA instrument and share these with multiple PC users for off-line analysis.

Educators can use it to demonstrate and explain transient RF effects, capturing a signal on a RSA and then having students analyze the signals on their own PC using RSAVu. Additionally, developers can use RSAVu to analyze a captured signal on the desktop, permitting the RSA to be used by other engineers.

Remote analysis
RSAVu also facilitates remote analysis. A single RSA instrument can acquire a data file and transmit this to a remote location for analysis. That can enable application developers and product experts to perform analyses no matter where they are in the world.

You can also make use of any purchased software options for an RSA unit on a PC by purchasing a USB software key. The USB key will enable purchased software options to function on a PC with RSAVu. Enabled software options on the key will match your instrument software option permissions. Note that the software options will only be available on the PCs when the key is installed. Multiple keys can be issued against a single instrument serial number.

RSAVu requires that the associated PC run Microsoft Windows XP or Windows 2000 operating systems.

The USB software key to enable access to software options purchased with a RSA unit is available for about $950. RSAVu is available as a free downloadable file on Tektronix's website.
