General description of the
used ROHDE & SCHWARZ FSIQ7
for sale.
The Rohde & Schwarz FSIQ 7 (1119.5005.17) Signal Analyzer provides in a single unit comprehensive and easy-to-use measurement functions in the, frequency, time and modulation domain. In the frequency domain, the R&S FSIQ 7 measures intermodulation and harmonics with great accuracy. The high 3rd-order intercept point in conjunction with the extremely low noise floor yields an intermodulation-free dynamic range of >110 dB and ensures reliable performance of even sophisticated measurements. The excellent dynamic range and the optimized phase noise values make the R&S FSIQ an ideal tool for ACPR (adjacent- channel power ratio) measurements in all mobile radio systems and in particular for WCDMA. The maximum ACPR value for WCDMA in 4.096 MHz bandwidth is 75 dB and is already attained at -12 dBm input level. In the time domain, the R&S FSIQ 7 features all modern capabilities of burst analysis in TDMA systems; gate functions, trigger delay and integrated RF trigger in conjunction with a short sweep time of 1 µs ensure precise measurement of the timing characteristics of all main mobile radio systems. In the modulation domain, the integrated vector signal analyzer provides diverse measurements on signals with digital or analog modulation. The variety of settings that can be called simply at a keystroke covers 18 mobile radio standards from GSM, NADC, IS95 through to WCDMA. These convenient presettings make it superfluous for the user to spend valuable time in looking up specifications and go towards enhancing the measurement reliability. Specifications.
