Calibration
User-characterized ECal
Storing user characteristics to the ECal module
Follow these steps to measure characteristics while an adapter is connected to the ECal
module and then to store them to the ECal module's built-in flash memory as user
characteristics.
NOTE
With the E5070B/E5071B with 2/3 ports (options 213, 214, 313, or 314), you cannot
measure the user characteristics of a 4-port ECal module and store them into the memory
by using this VBA macro.
1. Connecting ECal Module
Connect the USB cable between the USB port of the ECal module and that of the
E5070B/E5071B. You can make this connection while the E5070B/E5071B’s power is
ON.
2. Setting Stimulus Condition
Set the stimulus condition of the channel for which you want to measure the user
characteristics. For optimal accuracy, set the IF bandwidth to 1 kHz or less.
3. Executing Calibration
For the channel for which you have set the stimulus condition, execute full 4-port
calibration with a 4-port ECal module or full 2-port calibration between the test ports used
with a 2-port ECal module. Define the calibration surface as the connector surface
connected to each port of the ECal module in the state used to measure characteristics.
For information on how to perform calibration when the connector types of individual
ports differ, refer to “Calibration between Ports of Different Connector Types” on
page 155.
4. Starting the VBA MACRO
Step 1. Press .
Step 2. Press
Load Project
.
Step 3. The Open dialog box appears. Specify the file name “D:\AgilentEcalCharacterization.vba”
and press
Open
.
Step 4. Press to start the macro. The ECal part (1 in Figure 4-46) displays the
information of the ECal module connected to the E5070B/E5071B. Press
Refresh
(2 in
Figure 4-46) to update the information if you have connected another ECal module after
the macro has been started.
