We describe the Gauribidanur radio array solar spectrograph (GRASS) and its various systems. The system consists of an array of 8 log periodic dipoles,a spectrum analyzer and a data acquisition system. The spectrograph normally operates in the frequency range of 30 - 150 MHz with a frequency resolution of 250 KHz and a time resolution of 43 msec. The Gauribidanur radio array solar spectrograph operates approximately from 04:00 UT to 10:00 UT each day. We illustrate the working of the spectrograph with a few observations.
