Confidence Check on Calibration Coefficients Using ECal

Other topics about Calibration with ECal

Using the ECal module, the E5071C lets you verify the obtained calibration

coefficients to determine whether correct measurement is possible with

The E5071C can set ECal to the state used to verify the measurement

parameters and then copy the appropriate characteristics of that

verification state to the memory trace from the ECal's built-in memory.

This is done according to the measurement parameters of the active trace

of the active channel. While measuring ECal in this specified state, you can

compare the measurement results with those of the E5071C and with the

appropriate measurement results stored in ECal in several different ways.

These include simultaneously displaying the data and memory traces or

displaying the math operation results between the data and memory

traces. This enables you to verify the correctness of measurement for each

measurement parameter when the obtained calibration coefficients are

1. Connect the USB cable between the USB port of the ECal module and

that of the E5071C. You can make this connection while the

E5071C's power is ON.

2. Allows the ECal module to warm up for 15 to 20 minutes until the

module indicates from WAIT to READY.

you want to perform the verification.

5. Select the S-parameter you want to verify. You cannot verify the

mixed mode S-parameter.

6. Connect the test ports of the E5071C corresponding to the selected

S-parameter (for example, ports 1 and 2 when the S-parameter is

S21) and the ports of the ECal module.

7. If you don't use all of the ECal module's ports, connect terminations

to the unused ports.
