4 Expanding Your Measurement Experience
Testing the 8663A Internal/External 10 MHz
This measurement example helps you measure the absolute phase noise of an
RF synthesizer.
Required equipment
This measurement requires an Agilent 8663A in addition to the phase noise
test system and your device under test (DUT).
You also need the coaxial cables
and adapters necessary to connect the DUT and reference source to the test
set.
Defining the measurement
1 From the File menu in the E5500 User Interface, choose Open. If necessary,
choose the drive or directory where the file you want is stored.
2 In the File Name box, choose “Conf_SigGen_10MHz.pnm.” See Figure 35.
.
CAUTION
To prevent damage to the test set’s hardware components, do not apply the input
signal to the signal input connector until the input attenuator has been correctly
set for the desired configuration, as shown in Ta b le 6 on page 73. Apply the input
signal when the connection diagram appears.
NOTE
To ensure accurate measurements allow the DUT and measurement equipment to warm
up at least 30 minutes before making the noise measurement.
