Rohde & Schwarz FSP Spectrum Analyzers

5 models with full specifications from Rohde & Schwarz.

The Rohde & Schwarz FSP Series comprises high-performance, general-purpose spectrum analyzers engineered for demanding development and production environments. These instruments offer consistent RF performance, low level measurement uncertainty, and versatile digital filter options. Operating over a universal AC power supply of 100 V to 240 V, they provide a standardized platform for wireless communication testing, electromagnetic interference diagnostics, and general RF characterization. With an 8.4-inch color TFT display, a typical displayed average noise level (DANL) of -155 dBm, and a total measurement uncertainty of 0.5 dB, the FSP series serves as a reliable solution for technical environments. Users can select models based on maximum frequency needs, ranging from general RF bands up to microwave frequencies.

Frequency Coverage and Model Selection

The primary differentiator across the FSP family is the upper frequency limit of each analyzer. This allows matching the instrument to the specific spectral demands of your application:

  • Rohde & Schwarz FSP3: Best for general-purpose RF testing, covering a range from 9 kHz up to 3 GHz.
  • Rohde & Schwarz FSP7: Extends the measurement range to 7 GHz for cellular and wireless bands.
  • Rohde & Schwarz FSP13: Reaches up to 13.6 GHz, accommodating microwave link and radar testing.
  • Rohde & Schwarz FSP30: Spans up to 30 GHz for high-frequency microwave communications.
  • Rohde & Schwarz FSP40: Covers millimeter-wave applications up to 40 GHz.

Bandwidth and Filtering Characteristics

The series features robust filtering capabilities to resolve closely spaced signals and perform specialized noise measurements. The Rohde & Schwarz FSP3 and Rohde & Schwarz FSP30, for example, support a resolution bandwidth (RBW) range from 1 Hz to 10 MHz. FFT filters are available from 1 Hz to 30 kHz, and channel filters span 100 Hz to 5 MHz, including root raised cosine (RRC) shapes. Filter profiles on the Rohde & Schwarz FSP30 include Gaussian, RRC, FFT, Channel, and EMI types, allowing precise adjustments for specific transmission standards.

Standard Measurement Routines and Interfaces

The FSP series integrates several software measurement personalities and routine functions to automate complex evaluations. Built-in functions include third-order intercept (TOI), adjacent channel power (ACP and ACPR), occupied bandwidth (OBW), complementary cumulative distribution function (CCDF), and amplitude probability distribution (APD).

Hardware connectivity and integration options vary by model. For instance, the Rohde & Schwarz FSP40 features LAN, USB, GPIB, RS-232-C, VGA, PS/2, and parallel printer (LPT) interfaces. It also supports legacy command emulation for HP 859x and HP 8566 systems to facilitate easy automated test equipment (ATE) system integration.

Frequently asked questions

What is the typical warm-up time required for FSP spectrum analyzers?
