ROHDE & SCHWARZ FSIQ3 3.5 GHz Signal Analyzer Used ROHDE & SCHWARZ FSIQ3

The Rohde & Schwarz FSIQ 3 (1119.5005.13) 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 3 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 3 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. Frequency range: 20 Hz to 3.5 GHz. Frequency resolution: 0.01 Hz. External reference frequency: 10 MHz or n x 1 MHz, n = 1 to 16.

Product specifications of Rohde & Schwarz ROHDE & SCHWARZ FSIQ3 3.5 GHz Signal Analyzer (From Used-Line T&M Specifications)

  • Launch Date Jan-1998
  • Alternative R&S®FSU Spectrum Analyzer, R&S®FSQ Signal Analyzer
  • Status Discontinued by Manufacturer

The R&S®FSIQ Signal Analyzer is a one box solution in signal analysis. The FSIQ provides comprehensive and easy-to-use measurement functions in the Frequency, Time, and Modulation domains. With its extremely wide dynamic range, minimal measurement uncertainty and high flexibility, FSIQ from Rohde&Schwarz is the ideal instrument for development, verification and quality assurance but also in the production of base stations.

  • High measurement speed for use in development and production
  • Versatile test routines – convenient measurements
  • Applications for Mobile Radio - digital and analog
  • Spectrum analysis with ultrawide dynamic range for sophisticated ACPR measurements: NF = 15 dB/ TOI = +20 dBm (FSIQ7)
  • Integrated vector signal analyzer for universal analysis of digital and analog modulated signals BPSK to 16QAM, (G)MSK, AM, FM, PM
  • Vector signal analyzer for W-CDMA/3GPP
  • Symbol rate up to 6.4 Msymbol/s
  • High-speed synthesizer with 5 ms sweep time for FULL SPAN (FSIQ 3/7)
  • High display update rate up to 25 sweeps/s

The FSIQ family is a follow-on development from spectrum analyzers of the FSE series. Characteristics like dynamic range, accuracy and phase noise were further improved for highly demanding measurements on W-CDMA signals.

Because of the CDMA transmission used in mobile radio of the third generation, adjacent-channel power measurement is of particular importance. The wide dynamic range of the FSIQ is an essential feature especially when components like high-power output stages are measured, whose specifications must be far superior to those of the overall system. With a TOI of 20 dBm (FSIQ7), noise figure of 15 dB and typical phase noise of –153 dBc/Hz at 5 MHz from the carrier and –155 dBc/Hz at 10 MHz, FSIQ achieves more than 75 dB dynamic range in the adjacent channel and more than 85 dB in the alternate channel.

FSIQ models and frequency ranges:

  • FSIQ 3: 20 Hz to 3.5 GHz
  • FSIQ 7: 20 Hz to 7 GHz
  • FSIQ 26: 20 Hz to 27 GHz

FSIQ features:

  • Resolution bandwidth 1 Hz to 10 MHz in 1/2/3/5 steps
  • 5-pole resolution filters with high selectivity
  • FFT filter with 1 Hz to 1 kHz RBW for fast measurements
  • Displayed average noise floor typical -150 dBm in 10 Hz bandwidth
  • Third-order intercept +20 dBm with FSIQ 7, +22dBm with FSIQ26
  • Phase noise -150 dBc/Hz at 5 MHz offset
  • 75 dB ACPR dynamic range for W-CDMA (4.096 MHz integration BW)
  • Total measurement uncertainty <1 dB up to 2.2 GHz, <1.5 dB up to 7 GHz
  • RMS detector for high-precision power measurements irrespective of waveform
  • Fast spectrum analysis with 5 ms sweep time for full span (FSIQ3/7)
  • Fast time domain analysis with 1 µs zero span sweep time
  • Integrated broadband vector signal analyzer for all main mobile radio standards and modulation modes with versatile result display: I and Q signal, magnitude and phase, vector and constellation diagrams, spreadsheets with numeric evaluation of modulation errors and demodulated bit sequence
