How the probe can fulfill this requirement is mainly determined by its band width and CMRR e Low loading of the input signal Every probe is a load for the signal to be measured This means that the sig nal to be measured changes as soon as the probe is connected A good probe should cause only a minimum change to the signal so that the function of the DUT is not adversely affected How the probe can fulfill this requirement is mainly determined by its input impedance The parameters of a probe are usually specified for a minimally short connection between the probe and the DUT With longer connections the connection induc tance has a significant effect on the measurement The high frequency behavior of differential probes is typically characterized in the following environment The probe is connected to a differential 100 line that is fed by a source with 100 Q internal impedance and that is terminated into 100 Q The voltages at both inputs of the probe are always oppositely equal The fig ure 6 1 shows the equivalent circuit model of a probe that is connected to the DUT SS ee eee see User Manual 1410 4550 02 03 46 Circuit ground BR Fig 6 1 Equivalent circuit model of the R amp S RT ZD10 20 30 probe Table 6 1 Designations Abbreviation Description V Differential voltage between the test point without probe connected Differential voltage at the test point with probe connected corre sponds to the inp
