It is important to certify the instrument for science readiness at regular intervals. These are post maintenance quality checks (PMQC), at every stage of the GMRT sub-systems, on a regular basis. This is an important exercise to provide GMRT users with a best quality data for their science. We are re-visiting a series of tests, which would fulfill this goal for the upgraded GMRT. In this presentation, we list these tests, namely (i) antenna pointing, (ii) time and frequency stability, (iii) RFI monitoring, (iv) analog LO, (v) antenna deflection, i.e. its sensitivity, etc., and present our methodology and results. |
