Keysight N9912CU/238 Spectrum Analyzer Time Gating Option

Overview

The Keysight N9912CU/238 Time Gating Option transforms the FieldFox C-Series analyzer into a hybrid spectrum analyzer and oscilloscope for advanced RF pulse analysis. This option employs FFT gating (Gated FFT) to examine repeating waveforms and pulses in both the time and frequency domains, enabling detection and characterization of complex RF signals.

Key Features

• FFT Gating for efficient time-domain signal separation
• External trigger signal coordination for time-frequency analysis
• Measures signals separated in time (e.g., time-sharing radio signals)
• TDMA system signal analysis within specific time slots
• Excludes spectrum of interfering periodic pulse transients
• Oscilloscope-like pulse characterization capabilities

Applications

• RF pulse testing and characterization
• TDMA (Time Division Multiple Access) signal analysis
• Pulsed radar and communications signal measurement
• Interfering signal isolation in time-shared frequency systems
• Transient signal detection and exclusion

Requirements

• Requires option 233 (Spectrum Analyzer)
