While there may be other sensors that meet the required parameters, the
recommended USB power sensors are shown in
of these USB power sensors it will take approximately 1 hour for them all to
complete.
Recommended USB Power Sensors
Be sure to configure and test the communication with the power sensor
prior to executing this routine. This would also include zeroing and
calibrating the power sensor as needed.
If the following error occurs when running this routine, there is a required
adjustment missing. Go to the
section in this chapter and run the
517, Calibration Failure; Internal Channel Correction
Calibration(new)failure. Prerequisite calibration not completed.
Finalize BBG Assembly Installation
This is only used with an N5166B, N5172B, and N5182B.
This routine will run a few adjustments that are needed to ensure that the
instrument functions and performs properly with the new A2 Vector BBG
assembly and the existing A3 RF assembly. These adjustments are:
—Cal Array Defaults
—IQ Prelevel Calibration
—Open Loop Power Calibration
—IQ Calibration
—IQ Internal Channel Correction Calibration RF
—IQ Internal Channel Correction Calibration PM
These adjustments are built into the instrument calibration and test
harness. It will take approximately 1 hour for these adjustments to
complete, depending on the power meter/sensor used. Once this routine is
started it cannot be paused, only aborted. If aborted, it can only be started
again from the beginning.
For the last adjustment in this routine a power meter that can be controlled
by the instrument is required. This can be connected to the instrument
either via Sockets, VXI-11, or USB. However, the type of power
meter/sensor used can have a large effect on the amount of time the
