Example 1: 4200A-SCS with two 4210-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, 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 40 V
channels from five.
The next table shows the 4200A-SCS power requirements for valid combinations for the 4225-PMU,
4225-RPM, and high-power SMU.
