MAX9949和MAX9950参数测量单元

　　Abstract: This applicaTIon note explains the four main operaTIng modes for the MAX9949/MAX9950 parametric measuring units (PMUs). The operaTIng modes are: forced current/measure current (FIMI), forced current/measure voltage (FIMV), forced voltage/measure current (FVMI), and force voltage/measure voltage (FVMV). Block diagrams, equaTIons, and tables make it easy to verify a sample setup.

　　Introduction

　　The MAX9949/MAX9950 are dual-channel parametric measuring units (PMUs) that have four main operating modes:

　　FIMI—Forced Current/Measure Current

　　FIMV—Forced Current/Measure Voltage

　　FVMI—Forced Voltage/Measure Current

　　FVMV—Force Voltage/Measure Voltage
