Performance Verification Tests
Upper 3 dB Point Measurement
1. Move the marker to the right until the marker delta observed is just less than 3 dB.
a. Record the marker amplitude as y
1
.
b. Record the marker frequency as x
1
.
NOTE
: The marker must be one marker step away from the above 3 dB point and the marker delta
should be less than 3 dB.
2. Move the marker to the right one step.
a. Record the marker amplitude as y
2
.
b. Record the marker frequency as x
2
.
3. Calculate the lower 3 dB point frequency, x (assuming amplitude of y = -3 dB).
3 dB Bandwidth Measurement
1. Calculate the 3 dB bandwidth:
2. Record the 3 dB measurement bandwidth value for RF 2 OUT in the Test Record Card (see page
).

Measurement Uncertainty
The expanded uncertainty of measurement for this test (noted as the “Uncertainty” value provided in the
-- see page
) represents the standard uncertainty of measurement multiplied by the coverage factor
k=2. For normal distribution, this corresponds to a coverage probability of approximately 95%.
