DC Coupling for Low-Frequency Response
With the 480C02 / 480E09 connected as shown in Figure 5, the low frequency response of the coupling
circuit is determined by the relationship in Equation 2. This requires use of a BNC Tee. Figure 6 below
provides a comparison of AC vs DC coupling the same signal.
