Rohde & Schwarz Analyzers
11 models with full specifications in Analyzers.
This page summarizes Rohde & Schwarz instruments in the analyzer category — spectrum analyzers, a portable vector network analyzer, and specialist audio and TV analyzers. It explains how the product range is organised, the technical attributes that differentiate models (frequency coverage, dynamic noise floor, phase noise, resolution bandwidth), and practical guidance to match an instrument to common lab or field tasks. The notes cite representative models and their published specifications so engineers and technical buyers can identify which families to inspect more closely in the detailed model table below.

How the range is organised
Rohde & Schwarz offers distinct analyzer types rather than a single continuous product line. Key groups shown in the table below are:
- Portable vector network analysis: the ZVL6 is a compact, bidirectional 2‑port VNA for 9 kHz to 6 GHz with S11, S21, S12 and S22 measurement capability.
- General-purpose and lab spectrum analyzers: multiple models in the FSE/FS family cover different frequency and performance points — examples include the FS300 (9 kHz to 3 GHz), FSEB20 (9 kHz to 7 GHz), FSEM20 (9 kHz to 25.8 GHz) and FSEK30 (20 Hz to 40 GHz).
- High-dynamic-range / low-noise lab units: the FSU3 targets very low noise floors and wide RBW capability (20 Hz to 3.6 GHz).
- Specialist analyzers: the UPV is for precision audio analysis and the ETL is an all‑in‑one TV analyzer with RF coverage from 500 kHz to 3 GHz (expandable to 8 GHz).
Technical differentiators to watch
When comparing models, use these published specifications to narrow choices:
- Frequency coverage: top-end microwave coverage reaches 40 GHz on the FSEK30; mid‑microwave coverage examples include FSEM20 to 25.8 GHz and FSEB20 to 7 GHz; compact field and production analyzers include FS300 (9 kHz to 3 GHz) and ZVL6 for VNA tasks up to 6 GHz.
- Noise floor and dynamic range: DANL figures are a quick indicator — FSU3 lists -158 dBm (normalized to 1 Hz) and FSP13 -155 dBm (1 Hz); FSEK30 typ. DANL is -150 dBm in a 10‑Hz bandwidth. FS300 specifies dynamic range >137 dB and a typ. DANL of -120 dBm at 300 Hz RBW.
- Phase noise and linearity: FSEK30 quotes SSB phase noise <-113 dBc (1 Hz) at 10 kHz offset on a 1 GHz carrier; FSU3 lists -123 dBc (1 Hz) at 10 kHz offset. TOI and 1 dB compression are provided for several models (for example FSEK30 TOI +20 dBm typ., FSEK30 P1dB +10 dBm).
- Resolution bandwidth and sweep capability: RBW ranges vary by series (FSU3 up to 50 MHz RBW; FSEM20 and FSEK30 down to 1 Hz; FS300 RBW starts at 200 Hz), which affects measurement speed and narrowband sensitivity.
- Form factor and interfaces: portable instruments (ZVL6, FS300) emphasize compact size and lower weight; rack/bench units (FSEK30, FSEM20, FSU3) provide larger displays, extended I/O and higher power consumption.
How to choose — a practical checklist
Select by primary measurement task and the specs above:
- Vector network measurements (S‑parameters, impedance): consider the ZVL6 for a portable 2‑port VNA with 9 kHz to 6 GHz coverage and IF bandwidths down to 10 Hz.
- Wideband microwave spectrum analysis to mmWave-adjacent frequencies: inspect the FSEK30 (20 Hz to 40 GHz).
- Very low noise‑floor, precision lab work: prioritise models with the lowest DANL and widest RBW such as the FSU3 or FSP13.
- Field or production line work where size, power and robustness matter: the FS300 provides 9 kHz to 3 GHz coverage with >137 dB dynamic range in a compact package.
- Application-specific testing: use UPV for detailed audio metrics (0.1 Hz to 80 kHz, 2 channels) and ETL for TV/broadcast measurements (500 kHz to 3 GHz, expandable to 8 GHz).
Use the detailed model table below to match the exact RBW, phase noise and interface options required for your measurement workflows.

Frequently asked questions
- Which Rohde & Schwarz model is the portable VNA?
- The ZVL6 is the compact, bidirectional 2‑port vector network analyzer. It covers 9 kHz to 6 GHz, measures S11/S21/S12/S22, supports IF bandwidths from 10 Hz to 500 kHz and is specified at under 7 kg (base unit without battery).
- Which model covers the highest frequency?
- The FSEK30 provides the widest published frequency span in this set, from 20 Hz up to 40 GHz.
- Which analyzers have the lowest noise floor for sensitive measurements?
- Published DANL figures show the FSU3 at -158 dBm (normalized to 1 Hz) and the FSP13 at -155 dBm (1 Hz). The FSEK30 lists a typical DANL of -150 dBm in a 10 Hz bandwidth.
- What should I pick for audio or TV test requirements?
- Use the UPV for precision audio measurements (frequency range 0.1 Hz to 80 kHz, two channels, low THD+N) and the ETL for television network and broadcast measurements (500 kHz to 3 GHz, expandable to 8 GHz).
