The data you have, is it
A. 2-sec tick - price + tradesize
B. 2-sec bar (open/high/low/close) data
In either case you should be able to import them into a trading software for general backtesting.
For A, you need software that supports tick data directly.
For B, you need to check if your software support sub-minute data, if not, you will need to compress that into minute bar first before you can import the data.
