The HP 8168F tunable laser source is a basic tool for characterizing and testing optical amplifiers and components. The current values of wavelength and output power are indicated on a large and bright display. You can select both parameters independently within the specified range. If you change the output power, the wavelength remains stable, and if you change the wavelength, the output power remains stable. Just input a new wavelength and the instrument will set it immediately. With its coherence control mode made active, the HP 8168F will feature an effective linewidth of up to 500 MHz, thus drastically reducing the interference ripple. The internal modulation frequency is selectable between 250 Hz to 300 kHz for squarewave signals with 100% modulation depth (on/off). In the external modulation mode, the bandwidth is between 200 kHz and 20 MHz with a duty cycle depending on the input signal and a maximum modulation depth of ±15%. Specifications.
