N5182B
For the rest of the models in this series, and other assemblies for the models
listed above, nothing has ever been implemented for these function, so there
currently is no use of this menu for them.
For information on when these routines should be run see Chapter 16, “Pre and
Post-Repair Procedures”.
Finalize CPU Assembly Installation
Not used.
Finalize RF 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 A3 RF assembly
and the existing A2 Vector BBG 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
adjustment will take to complete. Because of this, the recommended
connection type is USB. When selecting a power meter/sensor to use for
this adjustment the following parameters need to be considered:
Frequency Range: 10 MHz to 6 GHz
Power Level: -70 to +20 dBm
