   Note: If you connect to the E5071C, please select the “ECAL.vba” file under the “E5071C” folder in the installation directory. The file with the same name under the “E5061B” folder cannot be used, and the two cannot be used in common.

6. In the macro setting soft panel, click [Select Macro].

7. In the Select Macro interface, click [Ecal SLK_Ecal] to start e-cal kit software.
   

8. Then the macro is embedded. User may use the macro to do the calibration.

Software Operation

The software simultaneously controls the vector network analyzer and the electronic calibration kit, coordinates the two to automatically complete the measurement of each standard, and corrects various system errors. Using the above solution, the same electronic calibration kit can be used on mainstream vector network analyzers, which breaks through the limitations of instrument manufacturers. Instruments of different manufacturers can use the same electronic calibration kit to complete the calibration. It greatly
reduces the cost of using electronic calibration technology, and significantly increases the scope of use of electronic calibration components.

4.1.User Interface
The soft UI has 2 windows:

• Connection window is used to build the connections.
• Measurement window is used to configure the calibration details.
• Connection window

As shown in the figure below, the interface for connecting the software to the instrument, the functions of each part are as follows:

【IP】
Specify the IP address of the vector network analyzer when controlling the vector network analyzer via LAN.
【Port Number】
The port number of the vector network analyzer SOCKET server.
【Address】
Specify the GPIB address of the vector network analyzer.
【Connect】
Connect the specified vector network analyzer through the specified method (LAN or GPIB), and the Information function block will display the connection result.
【Add Support】
When connected to a vector network analyzer, this instrument is not supported by this software, and the product model is not supported by the above
When the product model is selected, this button is activated. Select this button, and then the additional support module on the right will be activated.
【Add】
After confirming that the connected vector network analyzer model belongs to a certain product series listed in the list box, select the product series and click the [Add] button to add support. After the program is started next time, it will no longer prompt that the software is not displayed. Support this model.

• Measurement window
  

The functions of each part are as follows:
【Auto Check Port】
After selection, the corresponding relationship between the vector network port and the electronic calibration module port will be automatically matched.
【Prompt Infomation】
Prompt information.
【Reconnect】
After confirming that the ECal module is properly connected to the vector network, reload the ECal module information.
【Measure】
Perform calibration.
【Done】
Complete the calibration process.
【Quit】
Exit the software. 

4.2.Operation
The hardware environment required is: The hardware used for calibration includes electronic calibration kits, coaxial cables, USB cables used with the electronic calibration kits, vector network analyzers, and industrial computers (optional). The ECal module and the vector network analyzer are connected through a coaxial cable. If you need to switch, please plug in an adapter; connect the ECal module to the USB port of the vector network analyzer through a USB data cable.
The use of this software mainly includes the identification and connection of the vector network analyzer and the execution of calibration tasks.

• Identification and Connection of VNA
  Open the electronic calibration software. This software first initializes the system parameters, reads the relevant files, and then automatically scans the GPIB bus or the vector network analyzer available on the network. The connection interface is shown below:

If the VNA is connected to the industrial computer through the network, please fill in the IP address and port number. If the software is used in the VNA itself, please fill in the default IP address (127.0.0.1), the port number is provided by the instrument manufacturer, and Agilent is generally “5025”. If you connect via a GPIB cable, please fill in the GPIB address set at the vector terminal, and click the [Connect] button. If the connection is successful, go directly to the next step. If the connection is not successful, the display interface is as shown in the figure below.

At this time, it is necessary to confirm whether the instrument is connected correctly, whether the port connector is tightened, and whether the corresponding address is correct. After the connection is successful, if the driver supports this instrument model, click [Next] to directly enter the next module, if not, the display interface is as follows:

If the connected instrument belongs to a certain product series listed on the right, please select [Add Support], and the [Add] button on the right will become available. After selecting the corresponding product series and clicking [Add], the software can support this model. After the software is restarted, the software will support this model by default.

• Perform Calibration Tasks Module
  After successfully connecting with VNA, it will enter the calibration task module. The normal initial interface of this module is shown in the figure:

The leftmost list box allows you to select the type of calibration. For example, if you want to perform dual-port calibration, select “2 Port Cal” in the left list, and the right side will display the default vector network port and the calibration port corresponding situation. (1, 2) is the port number of the vector network analyzer, and (A, B) corresponds to the two ports A and B of the calibration part, here you need to set it according to the specific connection, for example, the vector network port 1 is connected to the calibration part B port, B should be selected in the second list box of the first row.
You can check [Auto Check Port] to specify automatic port connection detection. The software will combine specific algorithms to determine whether the port pair specified by the user is correct. If not, it will be modified for measurement. If it is not checked, the software will directly perform measurement regardless of port correspondence. At this time, make sure that the vector network port corresponds to the calibration unit port correctly.
Click the [Measure] button to perform a calibration measurement. The measurement completion interface is shown in the figure below.

Click the [Done] button, and the entire calibration process is completed.
Note: After the calibration is completed, be sure to click the [Done] button to end the calibration. Otherwise, the calibration status of VNA cannot be saved.

Troubleshooting

• Solution
  This warning means the frequency range of E-cal kit can not cover the frequency range of the VNA. 2 solutions for this situation.

1. Please re-configure the VNA frequency range and ensure it will not be wider than the E-cal kit frequency range.
2. Replace the E-cal kit with a wider frequency range model
   Then click [Refresh] button.

5.4.Ecaldll Failure

• Description
  When start the software a notice box pops out.

• Solution
  It caused by a broken or missing Ecaldll.dll Uninstall the software and re- install it.

• Description

• Solution
  Recheck the connection.
  Check the cable is firmly fixed on VNA.
  Check the connection cable
  Click [Measure] button and try again
  5.6.Collection Lost between VNA and control computer

• Description

• Solution
  The software used SCPI to communicate with VNA. VNA command error, W/R timeout, I/O failure will cause this error.
  Please try to restart the software and VNA and ensure the VNA is supported by E-cal kit.
  If the problem is not solved, please contact Saluki.
