Section 4: Pulse card concepts Model 4200A-SCS Pulse Card (PGU and PMU) User's Manual
4-6 4200A-PMU-900-01 Rev. A December 2020
Example 1: 4200A-SCS with two 4210-SMUs or 4211-SMUs, four 4225-PMUs, and eight 4225-RPMs.
The test uses all eight PMU+RPM channels set to the 10 V range (no SMUs in test).
PowerIDLE = [(29.4 * nPGU) + (50.4 * nPMU) + (4.2 * nRPM)] = [(29.4 * 0) + (50.4 * 4) + (4.2 * 8)]
= 201.6 + 33.6 = 235.2
PowerTEST = [(45 * nHPSMU) + (8.4 * nC10) + (54.6 * nC40)] = [(45 * 0) + (8.4 * 8) + (54.6 * 0)]
= 67.2
PowerTOTAL = PowerIDLE + PowerTEST = 235.2 + 67.2 = 302.4
This test has PowerTOTAL 500, so this test will proceed.
Example 2: 4200A-SCS with two 4210-SMUs or 4211-SMUs, four 4225-PMUs, and eight 4225-RPMs.
The test uses five PMU+RPM channels set to the 40 V range (no SMUs in test).
PowerIDLE = [(29.4 * nPGU) + (50.4 * nPMU) + (4.2 * nRPM)] = [(29.4 * 0) + (50.4 * 4) + (4.2 * 8)]
= 201.6 + 33.6 = 235.2
PowerTEST = [(45 * nHPSMU) + (8.4 * nC10) + (54.6 * nC40)] = [(45 * 0) + (8.4 * 0) + (54.6 * 5)]
= 273
PowerTOTAL = PowerIDLE + PowerTEST = 235.2 + 273 = 508.2
This test has PowerTOTAL >500, so this test will not proceed. Reduce the number of PMU+RPM
channels that are set to the 40 V range to less than five.
The following table shows the 4200A-SCS power requirements for valid combinations for the
4225-PMU, 4225-RPM, and high-power SMU.
