Keep the connection mode in step 7 unchanged and click the Measure Spectrum, and the compensation
program will carry out S3302 preamplifier OFF and preamplifier OFF data test, the screen will prompt the current
measurement tasks, and it will prompt to generate the “tc.tcdoc” file after the measurement is completed,
as shown in the following figure. When this file and “IFGainAtten.dc” are in the same folder,
the temperature compensation is completed.
