ECal is a calibration method that uses solid-state circuit technology. ECal offers the following advantages:
Simplified calibration process.
Shorter time required for calibration.
Reduced chance of erroneous operation.
Little degradation of performance due to wear ad tear because the ECal module employs PIN diodes and FET switches.
If the frequency sweep range exceeds the frequency range of the ECal, the calibration data for the minimum frequency or maximum frequency is used for the exceeding frequency range and extrapolation is executed.
Refer the following section for ECal calibration.
