Overview of the Test Set’s Built-In Tools
Using the RF Tools Program
Each RFTOOLS test includes two parts: calibration and measurement.
If the spectrum analyzer performs a self calibration between the
calibration and measurement of the RFTOOLS test, the spectrum
analyzer’s automatic self calibration instability will increase RFTOOLS
test measurement error. To avoid this problem, you may use this menu
item to turn off the spectrum analyzer’s self calibration. This self
calibration should only be turned off after the unit has reached a
constant powered-on operating temperature (approximately 30 minutes
after power-on), therefore it is probably best to leave it on. After 30
minutes, turning the self calibration off will improve the measurement
accuracy of RFTOOLS tests.
