RIGOL Chapter 1 Overview Chapter 1 Overview Test Preparations Before performing the test, make the following preparations. 1. The RF signal generator is stored for at least two hours under a temperature of 0℃ to 50℃ 2. 3. and is warmed up for 40 minutes. Make sure that the instrument is within the calibration period (1 year). The test devices required should fulfill the requirements of the "Specification" column in Table 1-1. You can also use the recommended models in the following table for the test.
