26.1 Frequency characteristics
Adjust the output level of the spectrum analyzer calibration unit (thereafter, “calibration unit”) so that the
displayed power value is -15dBm at each frequency for this unit, and measure the absolute value with a
receiver for calibration (microwave power meter, etc.).
