VSWR Measurement and Set-up for measurement

The  following steps will configure the Network Analyzer  with an "Adapter Removal" Calibration for measurement of the window..

Cal Kit Set-up:

1. Two Cal Kits are used.  One Cal Kit is the WG16x9 which has the "adapter" information.  The other Cal Kit is the WR2100_86 when using the 8.6" delay line of WR2100.
2. These Cal Kits need to be loaded into the Cal 1 and the Cal 2 storage locations under the "Calibration Menu" on the Network Analyzer.
3. Remember to set the Impedance to 1 ohm for the waveguide calibration.
4. Make sure there are three Cal Set storage locations before starting the calibration procedure.

Stimulus:

1. Center Frequency 476 MHz
2. Span 100 MHz

Calibration:

1. Perform a TRL calibration for Port 1 and Port 2 with the "Adapter" attached to Port 1 and Port 2 using the Cal Kit for the waveguide size of Port 1 and Port 2.
2. Store the Cal Set of Port 1 in storage location 1 and the Cal Set for Port 2 in storage location 2
3. The following steps are now a sequence of instructions using the buttons and questions on the screen of the network analyzer:

• MORE

• MODIFY CAL SET

• ADAPTER REMOVAL

• CAL SET FOR PORT 1 : CAL SET 1

• CAL SET FOR PORT 2 : CAL SET 2

• ADAPTER WG16x9

• MODIFY AND SAVE : CAL SET 3

For the "thru" portion of the calibration the set-up looks like this:

When doing the WR2100 Calibration, the set-up looks like this: (The adapter is part of the WG16x9 port.)

When doing the WG16x9 Calibration the set-up looks like this: (The adapter is now part of the WR2100 port.)
