Performance Verification Tests
Measurement Uncertainty
The insertion loss measurement is measured directly by the Agilent N5245A VNA. The VNA’s accuracy, when
measuring insertion loss, is specified to be ± 0.2 dB. For the purposes of this test, this is the expanded meas-
urement uncertainty.
If you use a VNA other than the Agilent N5245A (such as the other potential VNAs listed in the equipment list),
you will need to download the uncertainty calculator to calculate (worse-case) the uncertainty values for the meas-
urements you record in the
test record card (see page 41 ): www.agilent.com/find/na_calculator .
Insertion Loss below 10 MHz
Test Method
This test measures the insertion loss (below 10 MHz) of the M9360A, from the RF IN port to the RF 1 OUT port
and the RF 2 OUT port when in the preselector bypass setting. This test also measures the insertion loss (below 10
MHz) from the LO IN port to the LO 1 OUT and LO 2 OUT ports.
Limitations and Considerations
Methodology
This measurement is made using a signal source, two-resistor splitter and power meters/power sensors.
