I am using LabVIEW 7.1, PDA module, Daqcard 6036E, SCB-68, HP iPAQ. I know I can buy signal conditioning hardware but can I use software to linearized the thermocouple reading?
You will half to explicitly linearize the thermocouple reading in your program. With the DAQmx Base driver that you use with the PDA module, you can only read in the voltage from the DAQ card. You will then have to convert this voltage into the appropriate temperature.
