-SCS Pulse Card (PGU and PMU) User's Manual Section 2:
4200A-PMU-900-01 Rev. B March 2023 2-7
The RPM is matched to a PMU card and channel. Make sure to connect the RPM only to that PMU
card and channel. Labels on top of the RPM indicate the specific connection channel and PMU. For
example, "PMU1-2" indicates PMU1, channel 2.
With system power off, use the supplied RPM cable to connect a 4225-RPM to the matching RPM
channel of the 4225-PMU, as shown in the following figure.
Figure 6: 4225-PMU connection to an RPM
With an RPM installed, never make connections directly to any of the SMA connectors (CH1
and CH2) on the PMU. This may result in damage to the PMU or DUT. It may also produce
corrupt data.
After connecting or removing an RPM, always perform the procedure “Update the RPM
configuration” in Model 4200A-SCS Setup and Maintenance to ensure that KCon accurately
represents the present 4200A-SCS hardware configuration.
