Spectrum Analysis

233 – Spectrum Analyzer

Perform high-performance spectrum analysis with four trace options, different detector types, radio standard selection, and flexible limit lines.

235 – Pre-amplifier

Increase spectrum analyzer sensitivity and reduce the DANL.

236 – Interference Analyzer and Spectrogram

Identify interfering signals quickly and accurately using spectogram or waterfall display. Record traces over time and store them for offline processing.  

312 – Channel Scanner

Verify signal coverage, identify potential interference issues, and optimize network performance with channel power measurements of up to 20 channels at once.

Cable, Antenna, & Network Analysis

010 – VNA Time Domain

Display reflection or transmission coefficients in the time domain and remove unwanted responses with time-domain gating.

112 – QuickCal

Enable hassle-free calibration in the field for network analysis with no mechanical standards required.

210 – VNA Transmission / Reflection

Use vector network analyzer mode to measure transmission and reflection (S21 and S11) magnitude and phase.

211 – VNA full 2-port S-parameters

Enable vector network analyzer mode to measure all four S-parameters (S21, S11, S12, S22) magnitude and phase.

212 – 1-Port Mixed-Mode S-Parameters

Make balanced, mixed-mode S-parameter reflection measurements (Scc11, Sdd11, Scd11, Sdc11) with network analyzer mode.

215 – TDR Cable Measurements

Enable vector network analyzer mode to measure all four S-parameters (S21, S11, S12, S22) magnitude and phase.

305 – Cable and Antenna Analyzer

Troubleshoot and maintain the performance of RF cables and antennas.

308 – Vector Voltmeter (VVM)

Measure the phase shift and elctrical length of a device and view the results on the large display from a distance.

Power Measurements

208 – USB Power Measurements versus Frequency

Characterize the scalar transmission response of devices such as mixers and converters using USB power sensor measurements versus frequency.

302 – USB Power Sensor Support

Characterize RF pulses such as those used in radar and electronic warfare systems using a USB peak power sensor.

310 – Built-in Power Meter

Make accurate, user-definable channel power measurements such as transmitter output power with no additional external hardware.

330 – Pulse Measurement with USB Peak Power Sensor

Efficiently characterize pulsed RF signals by leveraging a Keysight USB peak power sensor.
