Use the RPM connectors on the 4225-PMU to connect it to the
(on page 5-6).
PMU block diagram
The next figure shows the block diagram of the PMU. Each channel has two dedicated A/D
converters to simultaneously measure current and voltage. The PMU controller controls the two
output channels and any RPMs connected to it. The solid-state relays (SSRs) are high-speed and are
used to test flash memory. The mechanical output relays are low-leakage. The block diagram for the
PGU is similar, except it does not have measure capability and does not have the RPM connectors.

Pulse modes
The PGU and PMU support the following pulse modes:
•
Standard pulse mode: For this two-level pulse mode, the user defines a high and low level for the
pulse output. The test modes for standard pulse are pulse I-V and waveform capture. See
(on page 5-40) for the standard (two-level) pulse mode.
•
Segment Arb
®
waveform: For this multi-level pulse mode, the user defines a pulse waveform that
consists of three or more line segments. Segment Arb pulse mode for the PGU and PMU
includes sequencing and sequence looping (see
(on page 13-125) and
(on page 13-128). Also see
(on page 5-56) for details
on parameters.
•
Full-arb pulse mode: For this multi-level pulse mode, the waveform consists of a number of user-
defined points (see
(on page 13-131) and
(on page 13-132)). Also see
(on page 13-131) for details on parameters.
KPulse supports all of these pulse modes.
