WARNING
Before connecting, disconnecting, or moving the test hookup, disable the output of the
signal generator to avoid causing the dangerous voltage.
1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in
Figure 5.3
.
2. Set the impedance of Fluke 9500B to 1 MΩ.
3. Output a DC signal with +3 mVdc voltage (Vout1) via Fluke 9500B.
