For the PMU, use this function to set the voltage source range for pulse output, set the
voltage and current measure range types, and set the actual voltage and current
measure ranges. For the PGU, use this function to set the voltage source range for
pulse output.
Measure range types for the PMU:
• Fixed: Use this range type to specify a fixed measure range (Vrange or Irange).
• Limited Auto: Select this range type to use the fixed measure as the lowest range
that will be used for automatic ranging.
• Auto: Use this range type to automatically select the optimum measure range. The
specified fixed measure range (Vrange or Irange) is not used in autorange
mode, but must be a valid range.
• The current ranges available depend on the source range and whether the system
includes a 4225-RPM, as shown in the next table.

Auto or limited autoranging is available only when using the advanced mode in the
pulse_exec function. Ranging is controlled per-channel and may be combined with load

Voltage measure range type (PMU):
0 = Auto
1 = Limited auto
2 = Fixed
Vrange_type parameter is ignored by the PGU. Autorange
(0) and limited autorange (1) are not valid for the Segment
ARB pulse mode.
Voltage measure range (PMU)
Vrange parameter is ignored by the PGU and is ignored by
the PMU when autorange is selected.
Current measure range type (PMU):
0 = Auto
1 = Limited auto
2 = Fixed
Irange_type parameter is ignored by the PGU. Autorange
(0) and limited autorange (1) are not valid for the Segment
ARB pulse mode.
Current measure range (PMU)
Irange parameter is ignored by the PGU and is ignored by
the PMU when autorange is selected.
