The QS2-1000 is a quasi-optical source composed of a QS2-180 (OV-86) backward wave oscillator (BWO), a Schottky diode frequency doubler, a low frequency tripler and one high frequency tripler. It is tunable across the 100 -180 GHz, 200-350 GHz, 300-500 GHz, and 600-1000 GHz freq.
Operation of the QS2 BWO system requires the use of a VR3 high voltage power supply. This power supply provides a voltage of up to 3 kV with very low line ripple. The power supply also has the option of adding a small modulating voltage to broaden the spectral line in order to help prevent standing waves in the optical setup.
Use of the QS2 system is greatly enhanced through the use of Microtech's DAU control device. This data acquisition unit controls the power supply voltage, allowing the user to control the frequency output of the system. It also includes an interface for THz detectors, a large aperture chopper, and software which can be used to analyze frequency spectra to calculate dielectric constants of a material.
