The Agilent N9320B is a 9 kHz to 3 GHz RF spectrum analyzer engineered for electronics manufacturing, R&D, bench repair, and RF education. It delivers essential spectrum analysis with minimum resolution bandwidth of 10 Hz for distinguishing closely spaced signals and displayed average noise level as low as −148 dBm (preamplifier engaged), enabling detection of low-level signals across the entire frequency range.

– Key Features
Power Measurements: Built-in analysis includes channel power, occupied bandwidth (OBW), adjacent channel power (ACP), spectrum emission mask (SEM), and third order intercept. Supports Agilent/Keysight U2000 series USB power sensors for extended RF and microwave power measurement capabilities.
Modulation Analysis Options: Optional AM/FM demodulation module (N9320B-AMA) provides carrier power, modulation rate, AM depth, frequency deviation, SINAD, and carrier frequency offset metrics. Optional ASK/FSK demodulation module (N9320B-DMA) delivers carrier power, error metrics, depth/deviation measurements, and four display modes: symbol, waveform, error, and eye diagram.
EMI Pre-compliance: Optional CISPR EMI filters (−6 dB) available at 200 Hz, 9 kHz, 120 kHz, and 1 MHz resolution bandwidths support pre-compliance testing with positive peak detector integration.
Stimulus-Response Measurements: Optional tracking generator (N9320B-TG3) extends capability to 3 GHz for component characterization and network analysis.
