Mid-Priced Spectrum Analyzers Set Speed, Accuracy Records

<%=company1%> Inc. (Beaverton, OR) is offering the FSP family of spectrum analyzers, a pair of value instruments that offer accuracy and measurement speed. The two new models are the FSP-3 (9 KHz to 3 GHz) and the FSP-7 (9 KHz to 7 GHz). The instruments are designed for high volume production test of second- and third-generation wireless handsets and base stations. The FSP-3 and FSP-7 spectrum analyzers support the TDMA, CDMA, and W-CDMA standards, and their accuracy and powerful measurement set make them well suited for system development tasks and general-purpose design use.

The FSP models achieve new benchmarks due to advancements in three key areas of spectrum analyzer performance: dedicated hardware processing for adjacent channel power ratio (ACPR) tests, substantial improvements in GPIB speed, and unmatched accuracy, which allows tighter measurement margins.

Channel power measurements, especially the computation-intensive ACPR test, have long been a barrier in the quest to reduce test time. The FSPs spectrum analyzers attack the problem with dedicated ASIC-based hardware for ACPR measurements. The instruments shrink ACPR test time from today's norm of up to several seconds to 100 ms or less.

The series boosts GPIB throughput with special production-test-oriented speed enhancements that yield a sustained GPIB rate of 30 measurements per second, including trace transfer. The instruments, for example, can bypass routine display update functions to deliver measurements more quickly over the bus. The pairing of increased GPIB speed with advanced ACPR technology makes the FSP family the industry's fastest solution, by far, for channel power measurements in production.

The total amplitude level uncertainty is 0.5 dB from 9 KHz to 3 GHz over a 70 dB dynamic range. Also included are an 8.4-in. color display, an update rate of 20 traces per second, automated tests such as occupied bandwidth, and signal statistics such as complementary cumulative distribution function (CCDF). Standard also are enhanced sweep speed and triggering configurations. Both portable and rack mount versions are available.

The FSP series was developed by Rohde & Schwarz, Germany, and is marketed and supported in North America by Tektronix under a strategic alliance formed in 1993. The series is available now and is U.S. priced starting at $18,950 for the FSP-3 and $25,950 for the FSP-7. For more information, call 1-800-426-2200 and request code 1176.
