Exercise 3.2: Building the RC Circuit and Measuring 10%-90% Rise Time of Waveforms
1. Configure the breadboard layout and VirtualBench connections for the RC circuit as explained below. Refer to
the schematic diagram and example breadboard layout (Figure 3.19) as well as the example connections to
VirtualBench (Figure 3.20).
Figure 3.19a. RC Circuit Schematic
Figure 3.19b. Breadboard Layout for RC Circuit
The RC circuit requires the following connections to the VirtualBench device (Figure 3.20):
Connect the positive output from the VirtualBench FGEN to the positive end of R1 (1 kΩ) (red wire on
breadboard)
Connect the positive end of C1 (1 µF) to the negative end of R1
Connect the negative end of C1 to ground
Connect the negative output from the VirtualBench FGEN to ground (black wire on breadboard)
Connect the positive input from CH1 of the VirtualBench MSO to the positive end of R1 (yellow wire on
breadboard); connect the negative input from CH2 of the MSO to ground (green wire on breadboard)
Connect the positive input from CH2 of the VirtualBench MSO to the positive end of C1 (blue wire on
breadboard); connect the negative input from CH2 of the MSO to ground (green wire on breadboard)
