2007•prints.iiap.res.inWe 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.
