What is the reference frequency stability of the FSV series?

Standard configurations of the FSV4 and FSV7 provide an internal reference aging of 1 x 10^-6 per year and a temperature stability of 1 x 10^-6. Equipping these analyzers with the optional R&S FSV-B4 OCXO improves the aging rate to 1 x 10^-7 per year and temperature stability to 1 x 10^-8.

Do these analyzers support external power sensors?

Yes. The FSV13, for example, natively supports Rohde & Schwarz NRP family power sensors for highly accurate, absolute RF power measurements.

What is the maximum safe input level for the RF ports?

The RF input (featuring an N female connector with 50 Ohm impedance on standard models like the FSV7 and FSV13) is rated for a maximum safe continuous RF power input of +30 dBm (1 W) and a maximum DC input voltage of 50 V.

Rohde & Schwarz FSV Series Signal and Spectrum Analyzers

5 models with full specifications from Rohde & Schwarz.

The Rohde & Schwarz FSV Series of signal and spectrum analyzers is built for high measurement speeds and reliable RF performance in development, production, and service environments. Designed for engineers and technical buyers requiring rapid analysis and versatile configuration options, the family spans five key models covering frequency ranges from 10 Hz up to 40 GHz. All models share an intuitive 8.4-inch touchscreen interface and a standard form factor, differing primarily in their maximum frequency limits, sweep parameters, and specialized bandwidth options. The series includes the FSV4, FSV7, FSV13, FSV30, and FSV40 models.

Frequency Ranges and Model Alignment

The primary differentiator across the FSV series is the maximum frequency ceiling, allowing users to choose the instrument best matched to their signal bandwidths:

FSV4: Covers 10 Hz to 4 GHz. It features a displayed average noise level (DANL) of -152 dBm (typical -155 dBm at 1 GHz, 1 Hz RBW) and a third-order intercept (TOI) of +16 dBm (typical +19 dBm at 1 GHz).
FSV7: Measures from 10 Hz to 7 GHz, targeted at standard wireless and RF development tasks.
FSV13: Spans 10 Hz to 13.6 GHz with a fine frequency resolution of 0.01 Hz, expanding capability into microwave bands.
FSV30: Extends coverage from 10 Hz up to 30 GHz, featuring a standard 28 MHz analysis bandwidth (upgradable up to 160 MHz) and a SSB phase noise of -110 dBc/Hz at 10 kHz offset.
FSV40: Serves high-frequency millimeter-wave applications, reaching up to 40 GHz.

Common Physical and Operating Architecture

The FSV series instruments share a physical layout and interface platform to simplify integration on test benches and in rack systems. The FSV4, FSV7, and FSV30 share identical dimensions of 412 mm x 197 mm x 417 mm, with weights ranging between 9.5 kg (FSV7) and 10.7 kg (FSV30).

Every model incorporates an 8.4-inch color touchscreen display with a resolution of 800 x 600 pixels. Standard connectivity features include Gigabit LAN and USB 2.0 host and device ports, allowing for remote system control and direct data acquisition. The FSV4 also includes a DVI-D output and supports an optional GPIB interface (via the R&S FSV-B9 option).

Measurement Functions and Filtering Options

The analyzers provide highly flexible bandwidth control, supporting resolution bandwidths (RBW) and video bandwidths (VBW) from 1 Hz to 10 MHz. For specialized applications, the FSV30 includes standard EMI resolution bandwidths (-6 dB) of 200 Hz, 9 kHz, 120 kHz, and 1 MHz, alongside channel filter bandwidths ranging from 100 Hz to 5 MHz.

Signal analysis is supported by multiple trace detectors—such as Max Peak, Min Peak, Auto Peak, Sample, RMS, Average, and Quasi-Peak—and essential trace functions (Clear/Write, Max/Min Hold, Average, and View). The platform also accommodates various optional software packages for analog demodulation (AM, FM, PM) and digital standards, including GSM/EDGE, WCDMA/HSPA, LTE, WiMAX, and WLAN.
