Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81635A #9108704 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 81635A Optical Tunable Filter (OTF) is an electronic test equipment used to control light sources in optical studies. This device uses a combination of wavelength tuning and electronic filters to precisely control the optical power output and other parameters of optical sources. HP 81635A OTF has two modes: a single-channel mode and a dual-channel mode. In single-channel mode, the wavelength of the light from the laser can be tuned from 320 nm to 1750 nm with a 1 cm-1 tuning resolution. In dual-channel mode, both channels can be independently tuned which gives twice the tuning range. This also allows for different wavelengths to be emitted from the two channels and thus further customization of your optical source. In addition to the wavelength tuning capabilities, AGILENT 81635A OTF also has multiple controls to adjust the optical power output of the source. The optical power can be adjusted in one of two ways. The analog output of the OTF can be adjusted using the voltage control knob which sets the direct current (DC) voltage supplied to the laser source. Or, the digital output of the OTF can be adjusted using software which provides more precise tuning of the optical power output. This electronic test equipment also includes other features that may come in handy for optical studies. The OTF has a built-in digital to analog converter (DAC) to convert digital signals to an analog output. It also includes a variety of optical sensor technologies to monitor different types of optical signals. Furthermore, KEYSIGHT 81635A OTF is compatible with many types of common optical fiber sources as well as laser sources. Overall, HEWLETT-PACKARD 81635A OTF is a versatile piece of electronic test equipment. It provides precise wavelength tuning and optical power output control which can be extremely useful when conducting optical studies. The built-in features make this device even more user-friendly and can save time and money when performing experiments.
