Rohde and Schwarz FSL18 - Spectrum Analyzer (9kHz - 18GHz) without Tracking Generator

You no longer have to make comprises when buying a spectrum analyzer. You can now get high-end features without stretching your budget - the R&S FSL.

The R&S FSL is a lightweight and compact spectrum analyzer that is ideal for a large number of applications in development, service, and production. Despite its compact size, it offers a wealth of functions more typical of the high-end range, thus ensuring an excellent price/performance ratio. The R&S FSL is the only instrument in its class that features a tracking generator up to 18 GHz and can analyze signals with a bandwidth of 28 MHz. In addition, the R&S FSL18, which operates at frequencies up to 18 GHz, supports applications in the microwave range.

The high-end approach is also evident in the operating features. When equipped with a tracking generator up to 18 GHz, the R&S FSL18 is an easily portable, microwave scalar network analyzer. As with the higher-class analyzers from Rohde & Schwarz, the main functions of the R&S FSL are directly accessible by fixed-assignment function keys, with additional functions accessed using softkeys and tables. This shortens the learning curve for new users.

Its compact size and low weight, plus its optional battery pack, make the R&S FSL ideal for mobile use.

The R&S FSL has unique plug and play upgrade abilities. All options can be added without opening the instrument.

Exceptional Performance for its Class

With phase noise of typ. -103 dBc (1 Hz) at 10 kHz from the carrier, a third order intercept point of typ. +18 dBm, a bandwidth range from 10 Hz to 10 MHz, and a displayed average noise level (DANL) of typ. -162 dBm, the R&S FSL compares favorably with high-end analyzers. This makes it very useful in production, service, field use and in labs. The RF attenuator, which is adjustable in steps of 5 dB, and the optional preamplifier ensure an optimum usable dynamic range.

Continuous RF Frequency Range from 9 kHz to 18 GHz and 28 MHz Demodulation Bandwidth

The R&S FSL is the only instrument in its class with a bandwidth of 28 MHz. Featuring an analysis bandwidth of 28 MHz, the spectrum analyzer is ideal for measuring both spectral and modulation parameters of broadband signals such as WLAN and WiMAX, including harmonic signals up to 18 GHz. In the time domain, its fast digitizer allows the detection of pulsed signals and the measurement of pulse widths.

The R&S FSL18 covers frequencies up to 18 GHz, which makes it ideal for a large number of development, service and production applications at microwave frequencies. Examples include the installation and maintenance of radar systems and microwave links, as well as the production of microwave components or satellite surveillance.

Fast and Versatile in Production

The R&S FSL's high speed of > 80 sweeps/s in zero span, including remote output of data (or trace data), ensures high production throughput. Even a simple level calibration can be streamlined and accelerated with the R& FSL's integrated complex measurement functions - a special multi summary marker measures different levels in the time domain in a single sweep. This eliminates reset and remote control overhead time. For fast synchronization or triggering, the R&S FSL-B5 additional interfaces option - which includes a special trigger interface - can be added.

In addition, the R&S FSL offers the following functions:

• Fast ACP measurements in the time domain for the major wireless communications standards, with very good repeatability and short measurement times
• List mode: measurements with up to 300 analyzer settings with a single IEC/IEEE bus command
• Fast power measurement in the time domain using channel or RRC filters
• Fast frequency counter with 1 Hz resolution and measurement times < 50 ms

At Home in Every Development Lab

The R&S FSL's excellent price/performance ratio makes it a must for every developer's lab bench, as indispensable as an oscilloscope or multimeter. Its range of functions and operation are largely identical with those of the R&S FSU high-end analyzers, simplifying the reproducible verification of measurements.

Lightweight and Compact for On-site Installation, Maintenance, and Service

The low weight (< 8 kg), the small size, and the ruggedized housing make the R&S FSL ideal for mobile applications. Due to these properties it is easy to carry to remote or hard-to-reach locations. The carrying bag with space for an extra battery pack and accessories and the protective hardcover are also very convenient for field use.

Optional Internal Battery Pack for Cordless Use

When equipped with the optional internal battery pack (R&S FSL-B31), the R&S FSL can be used independent of the mains supply for at least one hour. Easy and fast battery exchange in the field increases battery operation time. In addition, a DC power supply (R&S FSL-B30) is available for the R&S FSL. This option allows the R&S FSL to be used anywhere where DC power is available, e.g. in a car.

Power Measurements with R&S NRP-xx Power Sensors

Another special feature of the R&S FSL is the fact that you can directly connect a power sensor from the R&S NRP series. The R&S FSL-K9 option and a connected power sensor allow very precise measurements of the DUT power - an enormous advantage for applications where level accuracy is crucial. The R&S FSL can thus replace a power meter. This is particularly important in mobile applications.

Easy Upgrades and a Wide Range of Interfaces

The R&S FSL has unique plug play upgrade abilities. All options can be added without opening the instrument.

This has several important advantages:

• No extra alignment after installation
• No recalibration
• No need to send in the instrument, thus negligible downtime
• No installation costs
• Easy installation of additional functions

The wide range of additional interfaces provided by the R&S FSL-B5 option expands the application range of the R&S FSL:

• IF output/video output for connecting further instruments
• 28 V, switchable for connecting noise sources
• Trigger interface for fast measurement on frequency lists
• Connector for R&S NRP power sensors with ODU MIniSnap plug

Wide Range of Functions - Simple Operation

The R&S FSL offers a comprehensive set of measurement functions and features that are more typical of high-end analyzers. A versatile selection of firmware options helps save costs as a low-budget spectrum analyzer can be used whenever the specifications of a high-end spectrum analyzer are not required. An intuitive user interface supports users with measurements in line with standards. In addition, preconfigured, built-in measurement routines help the user to quickly get results.
