Figure 4-1. Gain Measurement
2. Connect the equipment as shown in Figure 4-1, then proceed as follows:
a)
Set the oscilloscope to DC, Time/cm to Ext. X, and gain to
l0mv/cm.
b)
Set the sweep generator to the video sweep mode with the start
frequency at 10 kHz and the sweep width to 10 MHz.
c)
Disconnect the 2400L from the set-up and connect the
sweep/generator RF output directly to the 30 dB attenuator.
