Loss
NOTE
[1]: Amplitude Loss (dB) = 20 x lg (Vrms2/Vrms1); wherein, Vrms1 is the measurement result of
amplitude effective value at 1MHz and Vrms2 is the measurement result of amplitude effective
value at full bandwidth.

Test Procedures
WARNING
Before connecting, disconnecting, or moving the test hookup, disable the output of the
signal generator to avoid causing the dangerous voltage.
Bandwidth test when the input impedance is 1 MΩ
1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in
Figure 5.5
2. Turn on Fluke 9500B and set its impedance to 1 MΩ.
3. Configure the oscilloscope:
