Rohde & Schwarz is positioning its FPL1000 series spectrum analyzer as a bridge between laboratory-grade benchtop instruments and portable field equipment. The unit weighs 6 kilograms and is 23 centimeters deep, while retaining core measurement functions and offering optional extensions for modulation, power and amplifier testing.

A portable form factor with laboratory ambitions

RF engineers have traditionally chosen between benchtop analyzers that prioritize performance and handheld devices that prioritize mobility. The FPL1000 series seeks to narrow that gap by combining a compact chassis with the measurement capabilities normally associated with larger instruments, according to the manufacturer's specifications.

The analyzer's base configuration covers channel power, adjacent channel leakage ratio, harmonic distortion and third-order intercept measurements. It also provides resolution bandwidth down to 1 Hz and includes spectrogram display, trace zoom and gated sweep functions as part of its core architecture rather than paid options.

Core specifications and measurement range

The FPL1000 lists a phase noise figure of -108 dBc (1 Hz) at 10 kHz offset on a 1 GHz carrier and a displayed average noise level of -166 dBm. Its standard analysis bandwidth is 12.8 MHz, with an optional upgrade to 40 MHz.

Optional extensions for specialized testing

The series can be configured with several application-specific options. The FPL1-K7 option adds analog modulation analysis for amplitude, frequency and phase-modulated signals, while FPL1-K70 supports vector signal analysis of digitally modulated single-carrier signals.

For frequency-response measurements, the FPL1-B9 option provides an internal continuous-wave source and tracking generator. The FPL1-K9 option allows compatibility with NRP power sensors across a range of -67 dBm to +45 dBm and frequencies up to 110 GHz. Amplifier characterization, including noise figure and gain, is supported by the FPL1-K30 option.

Data access and upgrade path

The analyzer's I/Q data can be exported for deeper analysis in third-party software, according to the specifications. Users can also expand the instrument's analysis bandwidth after purchase by installing the FPL1-B40 option, which raises the maximum from 12.8 MHz to 40 MHz.
