Calibrate the Vector Network Analyzer
There are two options for calibrating the VNA: use Option A or Option B as noted below.
Option A
. Using an Agilent N4691B ECal module:
1. Connect the ECal module to the VNA. ECal port A connects to VNA PORT 1, and ECal port
B connects to VNA PORT 2. Connect the USB cable between the ECal module and the
VNA.
2. Allow the ECal to warm up and indicate a READY status.
3. Perform a full two-port calibration on the VNA.
4. Press the
Cal
key on the VNA.
5. From the softkey menu, press
Start Cal
, and then
Cal Wizard
.
6. In the
Calibration Wizard Begin
dialog box, select
Use Electronic Cal
(ECal) and then
click the
Next
button.
7. Follow the ECal wizard instructions for a full two-port calibration, relying on the calibration
data stored in the ECal module.
Option B
. Using an Agilent 85052B Calibration Kit:
1. In the
Calibration Wizard Begin
dialog box, click
SmartCal
(GUIDED Calibration), use
Mechanical Standards
, and then click the
Next
button.
2. Follow the wizard instructions for a full two-port calibration.
3. When prompted for the type of thru calibration, select
