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.
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.
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.
| Model | Frequency Range | RF Input | VSWR |
|---|---|---|---|
| FSP3 | 9 kHz to 3 GHz | N female, 50 Ω | 1.5:1 (f <3 GHz) |
| FSP7 | 9 kHz to 7 GHz | N female, 50 Ω | 2.0:1 (f <7 GHz) |
| FSP13 | 9 kHz to 13.6 GHz | N female, 50 Ω | 2.5:1 (f <13 GHz) |
| FSP30 | 9 kHz to 30 GHz | Test port system 50 Ω, N female, 3.5 mm female | 3.0:1 (f <30 GHz) |

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.
