C / February 2017rpm_configThis command sends switching commands to the 4225-RPM.Usageint rpm_config(int instr_id, long chan, long modifier, long value);instr_id The instrument identification code: PMU1, PMU2, and so onchan Channel number of the pulse generator: 1 or 2modifier Parameter to modify: KI_RPM_PATHWAYvalue Value to set modifier:• KI_RPM_PULSE or 0: Selects pulsing (4225-RPM)• KI_RPM_CV_2W or 1: Selects 2-wire CVU (4210-CVU)• KI_RPM_CV_4W or 2: Selects 4-wire CVU (4210-CVU)• KI_RPM_SMU or 3: Selects SMU (4200-SMU)Pulsers4225-PMU with the 4225-RPMPulse modeStandard (two-level pulsing), Segment Arb, and full arbDetailsThe 4225-RPM includes input connections for the 4210-CVU and 4200-SMU. Use this command tocontrol switching inside the RPM to connect the PMU, CVU, or SMU to the output.When using the PMU with the RPM, rpm_config must be called to connect the pulse source to theRPM output. Note that if there is no RPM connected to the PMU channel, the rpm_config commandwill not cause an error. The RPM connection is cleared by the clrcon command.Examplerpm_config(PMU1, 1, KI_RPM_PATHWAY, KI_RPM_PULSE);This example sets channel 1 of the RPM for pulsing.Also seeclrcon (on page 13-199)
