Calibration Procedure Preparation
Before the calibration procedure is started, it is necessary to configure the UUT and also
set up the UUT personality in the PMUCal Software. The information in this section
describes the differences between the UUT configuration and the UUT personality
profile. For instructions on how to make or edit a UUT personality, see “Set Up a
Personality Profile” in Chapter 4.
UUT Configuration
The UUT configuration is the internal configuration settings of the UUT.
Note
It is not possible to change the UUT configuration items with the PMUCal
Software. To change the UUT configuration, refer to the UUT user
documentation.
The UUT configuration includes:
•
The nominal frequency of the UUT (F0).
•
The reporting rate of the UUT (Fs).
•
Class of the UUT. If necessary, contact the UUT vendor for instructions on how to
configure the UUT for P or M class performance.
When a connection is made to a UUT, the PMUCal Software requests the UUT
configuration information from the UUT and loads it into the configuration. If any of the
configuration information needs changed, disconnect the UUT, reconfigure it, and then
try again.
Note
If changes are made to the UUT configuration after you set up the UUT
personality profile (refer to “UUT and Simulator Personality Profiles”),
you must reconnect using the PMU Personality dialog in the Settings menu
to get the updated UUT configuration information.
Refer to the UUT user documentation for instructions on how to change the UUT
configuration.
UUT and Simulator Personality Profiles
UUT Personality Profile
The UUT personality profile is a file that stores unique information about the UUT that
can be changed with the PMUCal Software. The UUT configuration items are shown on
the UUT personality profile screen for reference. Figure 3-6 and 3-7 shows the UUT
personality profile screens.

Caution
To prevent inaccurate test results, it is important to use
accurate UUT information when you make a UUT personality
profile. To make the test results, the Calibration Software
compares the test results to the IEEE C37.118.1a-2014
performance limits for nominal frequency, reporting rate, and
class in the UUT personality profile. If incorrect information is
in the UUT personality profile, the results will be compared to
the incorrect IEEE C37.118.1a-2014 performance limits. The
IEEE C37.118.1a-2014 performance limits are significantly
different for each class.
