Measurement Calibration Procedure
1. Refer to “Measurement Calibration” on page 2-22 and perform the full 2-port
calibration on ES models or the enhanced response cal on ET models with the following
modifications:
2. Connect a testport cable with a female connector to PORT 2 (TRANSMISSION port on
ET models). Use the female standards (open, short, load) on PORT 1 (REFLECTION
Port on ET models) and the male standards (open, short, load) on the cable.
3. For the isolation measurement, select from the following two options:
• If you will be measuring devices with a dynamic range less than 90 dB, press:
• If you will be measuring devices with a dynamic range greater than 90 dB, 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 on PORT 1 (REFLECTION port on ET models). Connect a
load to PORT 2 (TRANSMISSION port on ET models).
b. Press .
c. Press to change the IF bandwidth to 10 Hz.
d. Press the following:
ES models:
ET models:
e. Return the averaging and bandwidth to the original state of the measurement,
and press the following:
