Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81689A #196895 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81689A optical attenuator is designed to provide a convenient method for accurately attenuating optical signals. It uses complex receiver and source circuit designs to deliver improved optical sensitivity and improved repeatability over the entire dynamic range. HP 81689A is suitable for testing optical components and systems in a variety of applications and environments. AGILENT 81689A offers two operating modes, variable attenuation and fixed attenuation. In the variable mode, the amount of attenuation of an optical signal can be varied continuously over a wide range. It also provides a control range of 0 dB to 80 dB. The fixed attenuation mode allows users to preset a certain amount of attenuation. 81689A features two output connectors, one for an optical source and the other for an optical receiver. This helps simplify optical test configurations. Additionally, the device includes a brightness menu. This allows users to quickly set the required output power of their optical source in terms of dBm. HEWLETT-PACKARD 81689A also includes a graphical user interface (GUI) which provides users with a simple way to configure and control the attenuator. The GUI allows users to easily configure the test mode, input and output ranges, and attenuation values. The device also incorporates an Autorange feature, which detects the input power range automatically and sets an appropriate attenuation range. KEYSIGHT 81689A has an extended operating range of -40°C to +65°C. This eliminates the need for many temperature-dependent calibration checks. It rigorously meets multiple industry standards for optical performance, making it well-suited for high-quality manufacturing and development test applications. The comprehensive device includes an optional Ethernet port and an analog input, while an optional external display allows users to fine-tune the output power of their optical source. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81689A offers users the capability to precisely and repeatedly attenuate optical signals. It has excellent optical performance and complies with major industry standards. The wide range of features, which includes variable and fixed modes, an Autorange feature, a graphical user interface, an extended operating temperature range, an optional Ethernet port, and an optional external display make the device well-suited for applications ranging from research to production.
