4 Verify the trigger sensitivity at maximum frequency for
trigger range of 8.0 V.
a Press the Mode/Coupling key, press the External softkey,
then press the Range softkey and use the Entry knob to
set the range to 8.0 V.
b Adjust the signal generator output for reading on the
power meter of 625µW. (500mV
pp
= 176.78mV rms,
Power = Vin

/50Ω = 176.78 mV

/50Ω = 625µW.)
c Check for stable triggering and adjust the trigger level
if necessary. Triggering is indicated by the Trig’d
indicator at the top of the display. When it is flashing,
the oscilloscope is not triggered. When it is not
flashing, the oscilloscope is triggered.
d Record the results as Pass or Fail in the Performance
Test Record (see page 70).
Test External Trigger Sensitivity (4-channel models)
The following test is optional because External Trigger
Sensitivity is a characteristic, not a specification.
This test applies to 4-channel models only.
Verify the external trigger sensitivity at these settings:
• 1 GHz, 500 MHz, and 300 MHz bandwidth models:
500 MHz, 500 mV
pp
• 100 MHz bandwidth models:
100 MHz, 500 mV
