Rohde and Schwarz FPL1007 - Signal and Spectrum Analyzer, 5 kHz to 7.5 GHz

The Rohde and Schwarz FPL1000 Signal and Spectrum Analyzer makes measuring fast and simple. The intuitive touchscreen is straightforward and easy to use. With its solid RF performance, light weight, and small footprint, the Rohde and Schwarz FPL1000 combines the functionality of a benchtop instrument with the portability of a handheld instrument.

One Instrument for Multiple Applications

The Rohde and Schwarz FPL1000 is a single measuring instrument for many types of measurements. You can use it for spectral measurements, for highly accurate power measurements with power sensors and for analyzing analog and digitally modulated signals.

Spectrum Analysis

Even in its basic configuration, the Rohde and Schwarz FPL1000 is a true allrounder. The basic configuration for spectral measurements includes:

Signal Analysis of Analog and Digitally Modulated Signals

Suitable measurement applications are available for analyzing analog and digitally modulated signals. The Rohde and Schwarz FPL1-K7 option turns the FPL1000 into an analog modulation analyzer for amplitude, frequency, and phase modulated signals. The base unit’s I/Q analyzer supports the magnitude and phase presentation of I and Q within the analysis bandwidth. The I/Q data can be exported for further analysis with third-party software products. The Rohde and Schwarz FPL1-K70 vector signal analysis option also analyzes digitally modulated single-carrier signals. The Rohde and Schwarz FPL1-K70M and Rohde and Schwarz FPL1-K70P options are extensions of the Rohde and Schwarz FPL1-K70 option for multi-modulation analysis and measurement of BER on PRBS data.

Other features that typically require costly options are already included in the base unit, e.g.:

Scalar Network Analysis

Equipped with the Rohde and Schwarz FPL1-B9 option, the Rohde and Schwarz FPL1000 offers an internal CW source and a tracking generator for quick and easy measurement of frequency response, filters, and attenuation. The n-dB down marker determines the 3 dB bandwidth of a bandpass filter at the press of a button. Precision is enhanced by through, short, and open normalization methods. In addition, the Rohde and Schwarz FPL1-B9 option allows characterization of two-port devices such as power amplifiers or limiters. The internal generator is in this case switched to power sweep mode (-50 dBm to 0 dBm), e.g. to perform measurements on amplifiers and determine their gain and 1 dB compression point.

Power Measurements with Power Sensors

For applications requiring high level accuracy, the Rohde and Schwarz FPL1-K9 option allows the Rohde and Schwarz FPL1000 to be used with Rohde and Schwarz NRP power sensors in a range from -67 dBm to +45 dBm and frequencies up to 110 GHz. The spectrum analyzer and the power meter modes run fully in parallel, effectively improving the measurement efficiency with a single instrument.

Noise Figure and Gain Measurements

For amplifier characterization, noise figure, and gain measurements can easily be performed with the Rohde and Schwarz FPL1-K30 option. This requires the Rohde and Schwarz FPL1-B5 additional interfaces option and an external noise source with a 28 V DC power input. Using the Y-factor method, noise figure, and gain are measured independent of the instrument’s own noise figure.

Phase Noise Measurements

Signals that are, for example, used for data transmissions (such as communications and Wi-Fi) often make use of the signal phase as part of the modulation technique. Phase noise will therefore result in increased bit error rates.

For these signals, it is important to ensure good phase noise performance (e.g. of the local oscillators). Phase noise measurements help to characterize the quality of these signals. The Rohde and Schwarz FPL1-K40 phase noise measurement application offers everything needed for this.

Solid RF Performance

Low Spurious Response

In order to distinguish spurs in the signal from spurs of the measuring instrument, a low spurious response is required. Within 10 MHz offset from the carrier signal, the specified spurious response of the Rohde and Schwarz FPL1000 is -70 dB lower than the signal level. This is over 10 dB better than comparable analyzers in this class. At higher offset, the specified value is even -80 dB, which is 20 dB better than comparable analyzers. This makes the Rohde and Schwarz FPL1000 the perfect tool for identifying interferers even when they are significantly below the carrier level.

Low Displayed Average Noise Level (DANL)

A low displayed average noise level (DANL) is required to detect signals with low levels. In addition, when you search for interferers above a certain level, a low DANL allows you to use a higher resolution bandwidth and to increase the measurement speed. With a typical DANL of -152 dBm, which can be improved to -166 dBm with a preamplifier, the Rohde and Schwarz FPL1000 can identify even small spurious emissions.

40 MHz Signal Analysis Bandwidth

The signal analysis bandwidth defines the frequency range in which all level and phase information over a given time is captured. The Rohde and Schwarz FPL1-B40 option extends the analysis bandwidth from 12.8 MHz to 40 MHz, making the R&S®FPL1000 the only instrument in its class that can demodulate analog and digitally modulated signals with up to 40 MHz bandwidth.

The Rohde and Schwarz FPL1-K7 option lets you analyze the amplitude, frequency, and phase of analog modulated signals. And the Rohde and Schwarz FPL1-K70 vector signal analysis option makes it possible to demodulate modulated single-carrier signals, and analyze them in detail.

The I/Q analyzer is the standard function for digital signal analysis. It displays the magnitude and phase parameters and the FFT spectrum. The captured I/Q data can be transferred to third-party software tools (e.g. Matlab or Python) for further analysis.

Low Level Measurement Uncertainty

Another unique feature in this class is the low level measurement uncertainty of 0.5 dB. The instrument’s high measuring accuracy ensures precise and reliable test results, which often makes it possible to dispense with a separate power sensor.

Precise Spectral Measurements Due to Low Phase Noise

The low phase noise of -108 dBc (1 Hz) at 10 kHz offset to the carrier (1 GHz carrier) yields significant advantages for spectral measurements as well. It enables accurate adjacent channel power measurements of narrowband carriers. Unwanted spurs close to the carrier can be detected.

Fully Portable

The Rohde and Schwarz FPL1000 Signal and Spectrum Analyzer can be used almost everywhere. With a depth of only 23 cm, it fits into any workplace and leaves enough space for DUTs and other measuring instruments. Due to its low weight of 6 kg and the carrying handle, you can take it wherever you need it.

Battery Pack and 12 V/24 V Power Supply (optional item, also available bundled in certain FPL1000 packages)

The optional battery pack provides three hours of operation. With additional batteries and an additional charger, the operating time can be extended without interruption.

When the Rohde and Schwarz FPL1000 is used in vehicles, the optional 12 V/24 V DC power supply conveniently supplies power via the car socket.

Carrying Bag and Shoulder Harness

A padded carrying bag is available for keeping the Rohde and Schwarz FPL1000 well protected during transport. Ventilation slits and a transparent cover allow the instrument to be operated while inside the bag. This lets you use the Rohde and Schwarz FPL1000 at any location and under adverse environmental conditions.

Users who need the functionality of a benchtop instrument and the flexibility of a handheld instrument can use the shoulder harness. Measurements where the instrument needs to be carried, such as interference hunting, are almost as convenient as with pure handheld instruments.
