Calibration Using 4-port ECal
The E5070B/E5071B allows you to perform calibration using the 4-port ECal module. It
provides much simpler operation than when using the 2-port ECal. Especially when using a
multi-port test set, calibration time and operator errors can be reduced significantly.
Operational procedure
To execute full 2-port calibration using the 4-port ECal module, follow these steps.
Step 1. Connect the USB cable between the USB port of the 4-port ECal module and the USB port
of the E5070B/E5071B. You can make this connection while the E5070B/E5071B’s power
is on.
Step 2. Connect the ports of the 4-port ECal module to the test ports you want to calibrate.
Figure 4-29 Connecting 4-port ECal module (for full 4-port calibration)
NOTE You can connect the ports of the ECal and the test ports of the E5070B/E5071B
arbitrarily.Connected ports can be manually specified although they are automatically
detected before data measurement.
For more information, “Turning off ECal auto-detect
function” on page 131.
NOTE If you don’t use all of the ECal module’s ports, connect terminations to the unused ports.
Step 3. Press or to select the channel for which you want to perform the
calibration.
