Keithley 4200A-SCS User Manual

Model 4200A-SCS Pulse Card (PGU and PMU) User's Manual Section 3: Setting up PMUs and PGUs in Clarius

Figure 66: Low-side measurement waveforms
The previous figure shows the current waveforms for both PMU channel 1 (high side) and channel 2
(low side) current measurements. Note that channel 2 does not show the capacitive charging effects.
Also, note that the channel 2 current measurement is negative because the current is flowing into
channel 2.
Figure 67: Setup for low-side measurement
In the previous figure, the voltage pulse is applied by channel 1; channel 2 does not pulse. Therefore,
there is no dV/dt, and therefore there are no charging or discharging currents during the pulse
transition. The red arrows show charging and DUT current for channel 1. The green arrow illustrates
the DUT current only for channel 2.
