2. Set the step attenuators to 0 dB, and set the generator for a 100 MHz output
and a power meter reading of --0.2 dBm for all instruments except Option 50
(0.0 dBm for Option 50 instruments).
3. Set the step attenuators to 10 dB (add 10 dB of attenuation to the 100 MHz
signal) and make a note of the Power Meter reading. This is the actual
attenuation of the 10 dB step.
