Product Overview

The Keysight Agilent E4404B ESA-L is a cost-effective, general-purpose laboratory spectrum analyzer designed for everyday RF and microwave measurements in R&D, production test, and field service environments. Part of the ESA-L series, the E4404B provides solid RF performance from 9 kHz to 6.7 GHz with resolution bandwidths from 1 kHz to 5 MHz, making it a versatile instrument for a broad range of applications.

Key Features
  • Broad Frequency Coverage: 9 kHz to 6.7 GHz, covering HF, VHF, UHF, and microwave bands up to C-band for comprehensive RF component and system testing.
  • Flexible Resolution Bandwidth: 1 kHz to 5 MHz in 1/3/10 sequence, enabling both wideband signal capture and narrowband spectral analysis.
  • Reliable Sensitivity: Displayed Average Noise Level (DANL) of -135 dBm (typ.), suitable for general-purpose signal detection and spurious emission measurements.
  • Good Phase Noise Performance: -90 dBc/Hz at 10 kHz offset (typ.), supporting adjacent channel power and close-in signal analysis.
  • Solid Dynamic Range: Third-order intercept (TOI) of +13 dBm (typ.) for distortion-free characterization of active RF components.
  • Amplitude Accuracy: ±1.0 dB total measurement accuracy, ensuring repeatable and dependable results for production line testing.
  • One-Button Measurements: Dedicated front-panel keys for Channel Power, Adjacent Channel Power (ACP), Occupied Bandwidth, Harmonics, and TOI measurements.
Built-in Demodulation and Analysis
  • FM Demodulation: Built-in FM demodulator with speaker output for audio monitoring of frequency-modulated signals.
  • AM Demodulation (Optional): Available with option for amplitude-modulated signal analysis.
  • Marker Functions: Up to 4 markers with delta marker, noise marker, and frequency counter modes for precise signal characterization.
  • Limit Lines and Pass/Fail: Configurable limit lines with pass/fail indication for automated production testing.
Remote Control and Automation
  • GPIB (IEEE 488.2) interface for integration into automated test systems with full SCPI command support.
  • RS-232 serial interface for simple remote control and data logging applications.
  • Parallel (Centronics) printer port for direct hardcopy output of screen traces and measurement results.
  • Fully compatible with Keysight IntuiLink and VEE software for PC-based instrument control and data acquisition.
Applications
  • RF component and subsystem testing (amplifiers, filters, mixers, oscillators, antennas)
  • Wireless communications device characterization (cellular, WLAN, Bluetooth, IoT)
  • Production line test and quality assurance for RF products
  • EMC pre-compliance conducted emission measurements
  • Education and university RF measurement laboratories
  • Field service and maintenance of RF communication systems
