2 Testing Performance
Test External Trigger Sensitivity
This test applies to all models.
Verify the external trigger sensitivity at these settings:
• 10 MHz, 250 mV
pp
in 8 V range
• 10 MHz, 50 mV
pp
in 1.6 V range (DSOX models)
• Max BW of oscilloscope, 500 mV
pp
in 8 V range
• Max BW of oscilloscope, 100 mV
pp
in 1.6 V range (DSOX models)
1 Connect the equipment (see Figure 5).
a Use the N cable to connect the signal generator to the power splitter input.
b Connect one output of the power splitter to the Ext Trig input through a 50Ω
feedthrough termination.
c Connect the power sensor to the other output of the power splitter.
