Key Steps for Every RCal Calibration
The following steps should be followed before every RCal calibration to
guarantee the best possible accuracy:
— RCal calibrations are independent of measurement time and temperature,
which are parameters that are handled through routine spectrum analyzer
alignments. For the best possible accuracy, alignments should be run
before every RCal calibration and after a 30 minute warm-up time. The RCal
module does not replace spectrum analyzer calibrations and alignments.
— Make sure that the Ext 10 MHz reference is connected and that the selected
USB connection supplies ample current.
— If source control is desired for the calibration, connect the necessary input
and output triggers between the analyzer and source.
