Measurement Calibration Procedure
1. Refer to the "Measurement Calibration" section in Chapter 2, "System
Verification and Performance Tests," and perform the full 2-port calibration
with the following modifications:
2. For the reflection measurements (short, open, loads), connect the calibration
device directly to the test port instead of to a reference test port. Use the
female devices for port 1. Adapt the male devices for port 2.
3. For the reflection measurements, use a cable configuration (a single cable or
cable pair) that is consistent with the normal use of the system.
4. For the isolation measurement, select from the following two options:
If you will be measuring devices with a dynamic range less than 90 dB,
q
press:
If you will be measuring devices with a dynamic range greater than 90 dB,
q
follow these steps:
a. Leave the cables connected and connect impedance-matched loads to
the test ports (or reference test ports).
Note
If you will be measuring highly reflective devices, such as filters,
use the test device, connected to the reference plane and
terminated with a load, for the isolation standard.
b. Press LAvg) $%$&@Z%&. &x ~~~~~~ WZ"$k (16) Ixl) to change the
averaging to at least 16.
e. Return the averaging to the original state of the measurement, and
