| 摘 要： | A new generation phase-sensitive detector based on a Texas Instruments TMS32010 digital signal processor has been designed and constructed may which be operated as a stand-alone instrument as well as under remote control from a desk-top computer through an IEEE 488 (GPIB) interface. The frequency, gain, bias and attenuation of the instrument are programmable.A 24 character 5×7 dot matrix alphanumeric display system and 16 digit keyboard are used to display the results of the inphase and the quadrature signals, and to change the programmable constants. The instrument is intended for use as a low frequency network analyser.
