Making Measurements

Measuring S-Parameters using a Two-Port Calibration

19. Assign User Cal Kit A to port 1. (This User Cal Kit is assigned to both

port 1 and port 2 since these ports are connected with the same
adapter during the calibration.) To do so:

• Press

. Use the front panel knob or the

keys to highlight Port 1 in the display’s table. Press

20. Start the calibration process by pressing

until the

Reflection Cal menu is displayed. Next, press

. If you want to correct for crosstalk errors, toggle ON

the

key. (For more information about isolation,

refer to the definition of a user two-port calibration in

Chapter 6

21. When the instrument prompts you to connect a through cable, insert

the female-to-female adapter between the test cables connected to
port 1 and port 2 as shown in

Figure 3-11

. Press
