NI PXI-5663 Calibration Procedure
2.
Reverification—Repeat the verification procedure for the NI 5663 to ensure that it is
operating within the device specifications after adjustment.
Initial Setup
Refer to the
NI 5661/5663/5663E RF Vector Signal Analyzers Getting Started Guide
for
information about how to install the NI-RFSA software and the NI 5663 hardware and how to
configure the NI 5663 in MAX.
Test System Characterization
These procedures characterize the test system response. Use the results of these procedures in
the
section of this document.
Measure the power splitter (and attenuation) response at the RF input frequencies used in the
verification tests.
Caution
The connectors on the DUT and test equipment are fragile. Perform the
instructions in this procedure with great care to prevent damaging any DUTs or test
equipment.
Power Splitter Reference Output
Designate either of the two outputs of the power splitter as the reference output.
Power Sensor Zero/Calibration
1.
Connect channel A of the power meter to power sensor A.
2.
Connect channel B of the power meter to power sensor B.
3.
Zero and calibrate the power sensors using the appropriate frequency for the calibration.
RF Input Calibration
This section describes how to calibrate the RF input you will use to verify the NI 5663.
Note
Perform the power sensor zero/calibration prior to the step. The power splitter
reference output must have been defined prior to the step.
RF Input Calibration (Without Attenuator)
Use the results of this procedure in the
Absolute Accuracy Verification
1.
Connect the power splitter input to the RF source output through the 3.5 mm-to-3.5 mm
cable.
2.
Connect power sensor A to the previously designated reference output of the power splitter.
