6: Clarius Model 4200A-SCS Parameter Analyzer
6-70 4200A-901-01 Rev. C / February 2017
DC Gnd operation mode - PMU
The operation mode for the PMU GND terminal.
PMU - all terminal parameters
When you select All Parameters, the Configure pane displays all available parameters for the test
that is selected in the project tree.
Parameter descriptions are provided in the following sections.
Start (PMU Amplitude Sweep)
The voltage source level at which the sweep starts.
Stop (PMU Amplitude Sweep)
The voltage source level at which the sweep stops.
Step (Pulse Amplitude Sweep)
The voltage size of each step of the sweep. The source level changes in equal steps of this size from
the start level to the stop level. A measurement is made at each source step (including the start and
stop levels).
Clarius never steps the force voltage beyond the value specified by the stop parameter, even if you
specify a step value that is larger than the stop value.
Use a step value that does not result in a fractional number of data points. If the data point is
fractional, the step value is forced to a value that results in a whole number of data points. To
calculate the data points:
The data points are rounded to the nearest value.
For example, if Start = 0 V, Stop = 5 V, and Step = 0.6 V:
In this case, the Step value is forced to 0.625 V, which results in a data point value of 9.333, which is
rounded to 9. The instrument forces nine voltages at 0 V, 0.625 V, 1.25 V, 1.875 V, 2.5 V, 3.125 V,
3.75 V, 4.375 V, and 5 V.
Points
The number of data points that will be measured. This value is calculated by Clarius using the
information entered for the Start, Stop, and Step parameters, using the equation:
