Making Measurements
Using RCal Directly from the 89600 VSA
To address this, you can connect the U9361 RCal receiver calibrator to the
whole receiver system, either conducted or over-the-air (OTA). Then execute
the calibration procedure as described in prior section and apply the resultant
calibration coefficients to your 89600 VSA measurements. With the calibration
process, it will improve the whole wideband receiver system performance
including absolute power accuracy, and EVM result accuracy including the
magnitude and phase error.
From a Receiver Calibration to a Comprehensive End-to-End
Calibration
Having successfully calibrated the receiver system with the RCal with 89600
VSA, the next phase involves an end-to-end calibration. This is achieved with
the N7618APPC PathWave AWU (Advanced Waveform Utility) software,
encompassing both the source and analyzer. With the receiver already
calibrated, the next step is to calibrate the source (and associated
components). The final outcome includes both source and analyzer calibrated
to the reference plane of the DUT for precise measurements.
The figure below shows how to perform an end-to-end system calibration
using RCal 89600 VSA and PWSG AWU software.
In conclusion, the U9361 RCal receiver calibrators bring accuracy, efficiency
and value to calibration of your test receiver system by allowing you to move
the reference plane to the device under test (DUT). 89600 VSA software with
2024 patch release now can connect with RCal to perform the calibration and
