ECal (electronic calibration)

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 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 are used for the exceeding frequency range and extrapolation is being executed.

• When using Ecal with the E5071C options 2D5, 4D5, 2K5 and 4K5 , wait time is inserted automatically for stable calibration results. Approximate calibration time is described in the support ECal page.
