Keysight, Fluke, Tektronix, Teledyne LeCroy, Rohde & Schwarz all have distributors and / or sales offices in India. I am surprised the OP seems to have had some difficulty finding Keysight distributors - there are more than 15 of them in India, and they can be found using the 'Find a Partner' link on the Keysight homepage, near the bottom of the page.
