RF, Microwave, and Handheld Signal Analyzers
Keysight's RF and microwave spectrum and signal analyzers split into economical benchtop, specialized, and ruggedized handheld instruments. Benchtop units like the N9320A and N9320B cover 9 kHz to 3 GHz, serving as general-purpose instruments for manufacturing and basic research. The X-Series N9000A CXA analyzer offers broader frequency flexibility up to 26.5 GHz with configured options.
For field installation and outdoor environments, the FieldFox handheld series, including the N9914A, N9915A, N9917A, N9917B, N9918A, and the N9952A, deliver benchtop-level precision. These units combine cable and antenna test (CAT), vector network analyzer (VNA), and spectrum analyzer (SA) functionalities in an IP53-rated chassis, with the N9952A extending measurements up to 50 GHz. Specialized field and lab requirements are addressed by the N1996A CSA spectrum analyzer, the N9340A handheld RF spectrum analyzer (covering up to 3 GHz), and the E7405A EMC standard analyzer, which includes built-in preamplifiers and standard EMI detectors for precompliance troubleshooting.

In real-time environments, the DSA91204A Digital Signal Analyzer delivers 12 GHz bandwidth and up to 40 GSa/s real-time sampling across 4 channels. Finally, the 8991A Peak Power Analyzer provides dual sensor channels and dual oscilloscope channels to characterize pulsed RF signal profiles.
Impedance, Material, and Semiconductor Parameter Analyzers
Precision impedance and material analyzers from Keysight cover component characterization across various frequency ranges. The 4192A covers low frequencies from 5 Hz to 13 MHz, while the 4294A extends from 40 Hz to 110 MHz with a 0.08% basic impedance accuracy. The E4990A benchtop impedance analyzer supports continuous frequency coverage up to 120 MHz, matching the 0.08% basic accuracy. High-frequency material evaluations up to 1.8 GHz are performed by the 4291B, while the 4194A combines impedance analysis (up to 40 MHz) with transmission gain-phase analysis.
For active semiconductor device profiling, Keysight's family of parameter analyzers includes the legacy 4145B and the 4155A, 4155B, 4156A, and 4156C laboratory models. Mainframes like the 4156A and 4156C feature high-resolution source/monitor units (HRSMUs) with sub-picoampere current measurement resolutions (down to 1 fA for the 4156A) for delicate parametric characterization of devices and materials.

Digital system debugging and timing validation are addressed by the 16800 logic analyzer family, including the 34-channel 16801A, the 102-channel 16803A, and the 204-channel 16806A, which provide timing zoom up to 4 GHz. The 16822A and 16823A expand on these diagnostic capabilities by integrating a 48-channel digital pattern generator to supply stimulus-response logic analysis.
For system power profiling, the N6705A, N6705B, and N6705C DC Power Analyzers integrate up to four advanced DC power modules or electronic loads, offering up to 600 W of combined output power with integrated DMM and oscilloscope digitizing rates up to 200 kHz.
Telecommunications network testing is addressed by the portable 37717B and 37718A communications performance analyzers, which provide error and jitter analysis for SONET and SDH networks. For audio-frequency evaluation, the two-channel U8903A Audio Analyzer covers 10 Hz to 100 kHz with system THD+N of less than -101 dB.
Frequently asked questions
