3: Setting up PMUs and PGUs in Clarius Model 4200A-SCS Pulse Card (PGU and PMU)
3-12 4200A-PMU-900-01 Rev. B March 2023
Report Status (PMU)
When this option is selected, Clarius records measurement status information when the test executes.
A column of the Analyze spreadsheet displays this information. Hover over a cell to review the
information. An example of the status information is displayed in the following figure.
Figure 40: Report Status for PMU in the Analyze sheet
For PMU measurements, this information is also available as a 32-bit word. The status code bit map
is listed in the LPT pulse_fetch command description.
PMU measurement status
ITMs can provide status information for the 4225-PMU measurements in the Analyze sheet Run tab.
The column for the status codes is labeled PMUx_y_S, where x is the PMU instrument number
(PMU1, PMU2, and so on), and y is channel number (channel 1 or 2). The PMU status code indicates
pulse measurement status, source and measure ranges, whether an RPM is connected, and load-line
effect compensation (LLEC) status, and flags any faults (errors).
If a pulse measurement fault occurs, the data values in the entire row are displayed in a different color.
A single measurement may have more than one condition. Hover over a cell to review the
status information.
The data values identify the fault type as follows:
• Red = Source in compliance
• Magenta = Measurement overflow
• Orange = LLEC failed
• Blue = Current, voltage, or power threshold reached
An example of the Analyze sheet when a measurement overflow occurred is shown in the following
figure. The figure also shows an example of the message that is displayed when you place the cursor
on a flagged PMU1_1_S cell.
