Figure 2-1 ECal Model and Serial Numbers on the Backside of the ECal Module
The ECal kit serial number is intended for identification purposes whenever an
ECal kit is returned to Keysight for repair or recertification.
ECal Module Serial Number
The serial number is located on the backside of the ECal module (refer to
Figure 2-1 ). Each ECal module is unique and is individually serialized. The
serial number is stored in the ECal module memory and may be accessed by a
network analyzer when the ECal is used to perform a calibration. Test reports
for an ECal module will refer to this serial number as the “ECal S/N.”
