The Rohde & Schwarz FSP is a family of spectrum analyzers offered in five frequency tiers — FSP3, FSP7, FSP13, FSP30, and FSP40 — each beginning at 9 kHz and extending to an upper limit of 3, 7, 13.6, 30, or 40 GHz respectively. Frequency resolution reaches 0.01 Hz, and frequencies are read out using a marker or an integrated frequency counter with selectable resolution from 0.1 Hz to 10 kHz.

Beyond general spectrum measurements, the FSP platform hosts a broad set of optional application firmware packages for specific signal standards, including GSM/EDGE, 3GPP WCDMA and TD-SCDMA, CDMA2000, Bluetooth, WLAN 802.11a, and WiBro/WiMAX (IEEE 802.16 OFDMA), as well as dedicated phase-noise and noise-figure measurement firmware. Each of these is a separately ordered software option rather than a base-unit feature.

ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house before it ships, while new units leave the warehouse factory-sealed exactly as received.

Brand Heritage

Rohde & Schwarz is a privately held German electronics company that has operated under its founders' names since its establishment, with no major corporate rebranding or acquisition changing its identity.

Compare Other Models in This Series

The R&S FSP series comprises five spectrum analyzers that share a common architecture and differ principally in their upper frequency limit. All five models — FSP3, FSP7, FSP13, FSP30, and FSP40 — start at 9 kHz, with maximum frequencies of 3, 7, 13.6, 30, and 40 GHz respectively.

Across the series the instruments share the same resolution-bandwidth range, detector set, display, and remote-control interfaces, so the choice between models is driven primarily by the frequency coverage and RF connector system a given measurement requires.

Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the FSP model whose frequency coverage and option compatibility match your application, then choose the pre-owned listing that fits your requirements and budget.

The models differ in upper frequency limit (3 GHz to 40 GHz), RF input connector system, and input VSWR — 1.5:1 below 3 GHz rising to 3.0:1 on the higher-frequency models — as shown in the comparison table. Typical weight also ranges from 10.5 kg to 12 kg across the series.

Option availability is model-dependent: the electronic attenuator with integrated preamplifier (FSP-B25) is offered only for the FSP3 and FSP7, while the LO/IF ports for external mixers (FSP-B21) are available only on the FSP40. Consult each model's row in the comparison table for its specific frequency range and supported options.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Accessories Supplied

• Power cable
• Compact manual
• CD-ROM with operating manual and service manual
• Test port adapter with 3.5 mm female (1021.0512.00) and N female (1021.0535.00) connector

Product Core & Specifications

Important: Maximum input level: +30 dBm CW RF power with RF attenuation ≥10 dB, and 50 V DC at the RF input.

Important: Specifications are valid under the following conditions: 15 minutes warm-up time at ambient temperature, specified environmental conditions met, calibration cycle adhered to, and total calibration performed.

Important: Data without tolerances are typical values only. Data designated "nominal" applies to design parameters and is not tested. Data designated "σ = xx dB" is shown as standard deviation.

Important: Recommended calibration interval: 2 years for operation with external reference, 1 year with internal reference.

Important: Maximum permissible DC input voltage at the RF input is 50 V for the ¸FSP3/¸FSP7/¸FSP13 and 0 V for the microwave-input ¸FSP30/¸FSP40; with option ¸FSP-B29 (frequency range extension 20 Hz) the maximum DC input voltage is 0 V.

Important: The ¸FSP30 and ¸FSP40 are supplied with test port adapters; alternate connectors (e.g. 3.5 mm male, N male, K male, 2.4 mm female) are available as recommended extras (see "Recommended extras for alternate connectors").

Usage tip: for portable or field operation, pair the FSP with the R&S FSP-B30 DC Power Supply and the FSP-B31/-B32 Battery Pack listed in the ordering information.
