Making Preparations for Measurements
3
When using the current probe (700937, 701930, 701931, 701932, or 701933), the
number of probes that can be used is limited by the current generated by the device
under measurement (current measured by the current probe). The characteristics of the
measured current versus the current consumption of an active probe that can be
connected to the DL7400 are shown below.
