Keysight / Agilent / HP 8164A Lightwave Mainframe with 81682A Tunable Laser Source

The Keysight 8164A Lightwave Mainframe paired with the 81682A Tunable Laser Source delivers a modular platform for optical component characterization across the C-band. The 8164A mainframe accepts one tunable laser source module plus four additional compact optical modules, enabling flexible test configurations. The 81682A provides mode-hop free tuning across 1460 nm to 1580 nm with ±0.01 nm absolute wavelength accuracy and ±0.5 pm repeatability, making it well-suited for DWDM component validation and optical system development. ## Technical Specifications 81682A Tunable Laser Source • Wavelength range: 1460 nm to 1580 nm (C-band) • Maximum output power: +8 dBm • Output power (1520–1570 nm): >+4.5 dBm • Wavelength accuracy (absolute): ±0.01 nm • Wavelength repeatability: ±0.5 pm (typical) • Wavelength resolution: 0.1 pm • Dynamic range: >60 dB (via optional built-in attenuator) 8164A Mainframe • Slots: 1 dedicated TLS slot + 4 module slots • Display: Graphical color display, 600 × 400 pixels • Interfaces: GPIB, RS-232C serial, Centronics parallel, VGA, PS/2, PCMCIA 2.1 • Storage: 2000 MB internal HDD plus ATA/SRAM card support • Power: 100–240 VAC ±10%, 48–66 Hz, 120–280 VA max • Operating temperature: +10°C to +35°C • Storage temperature: −40°C to +70°C • Humidity: <80% R.H. (non-condensing) ## Key Features • Mode-hop free tuning for continuous wavelength scanning • Extensive triggering with configurable hardware I/O ports • Passive component test, stability logging, and data acquisition built-in • PC Card slot enables field data transfer and firmware updates • Supports all 8153A and 8163A series optical modules for multifunction measurement capability ## Typical Applications • DWDM filter and multiplexer characterization • Tunable laser source validation and stability testing • Wavelength-dependent optical component measurement • Manufacturing test environments requiring automated scanning ## Compatibility & Integration The 81682A mounts directly into the 8164A mainframe. Additional optical modules - power meters, return loss modules, fixed sources, attenuators, and optical switches - occupy the four remaining slots. Remote control via GPIB or RS-232C enables integration into automated test systems.
