2 Testing Performance

2 Verify the trigger sensitivity at maximum bandwidth.
1 GHz models: 1 GHz
500 MHz models: 500 MHz
300 MHz models: 300 MHz
100 MHz models: 100 MHz
a Press the Save/Recall key, then press the Default Setup
softkey.
b On 300 MHz, 500 MHz, and 1 GHz models, set channel 1
Imped to 50 Ohm.
c Set the output frequency of the signal generator to the
maximum bandwidth of the oscilloscope and set the
amplitude to about 10 mV
d Press the AutoScale key.
e Set the time base to 10 ns/div.
f Set channel 1 to 5 mV/div.
g Decrease the amplitude from the signal generator until 1
vertical division of the signal is displayed.
The trigger is stable when the displayed waveform is
stable. If the trigger is not stable, try adjusting the trigger
level. If adjusting the trigger level makes the trigger stable,
the test still passes. If adjusting the trigger does not help,
see the "Troubleshooting" chapter. Then return here.
h Record the result as Pass or Fail in the Performance Test
Record (see page
3 Repeat this procedure for the remaining oscilloscope
channels.
