Zcal overview

Use the Zcal utility as an alternative to the Zauto utility to display and enter reflectivity calibration numbers in the calibration file when:

• First setting up a system, before final calibration.

• Resetting reference calibration information.

  Reference information is applicable only on systems that automatically run calibration. If a new calibration deviates too much from the reference, it is not used. This prevents loss of data if the signal generator fails.

Zcal does not have a graphical interface. There are separate calibrations for each pulse width and polarization as applicable.

For information on the reflectivity channel calculations, see RVP10 User Guide (M212604EN).
