Figure 8 Setting Up Equipment for Internal Trigger Sensitivity Test
b Set channel 1 Imped to 50 Ohm.
4 To verify the trigger sensitivity at the oscilloscope’s
maximum bandwidth, set the output frequency of the
signal generator to the maximum bandwidth of the
oscilloscope:
• 1.5 GHz models: 1.5 GHz and 1 GHz.
• 1 GHz models: 1 GHz.
• 500 MHz models: 500 MHz.
• 350 MHz models: 350 MHz.
• 200 MHz models: 200 MHz.
5 Perform these steps to test at the 5 mV/div setting:
a Set the signal generator amplitude to about 10 mV
pp
.
b Press the [AutoScale] key.
c Set the time base to 10 ns/div.
d Set channel 1 to 5 mV/div.
