2 Set up the oscilloscope.
a Press the [Default Setup] key.
b Press the [Mode/Coupling] key; then, press the Mode
softkey to select Normal.
3 Change the signal generator output frequency to 100 MHz
or 200 MHz.
4 Set the power meter Cal Factor % to the appropriate
value (100 MHz or 200 MHz) on the calibration chart on
the power sensor. If necessary, do a linear interpolation if
a 100 MHz or 200 MHz factor is not included in the
power meter's calibration chart.
5 Adjust the signal generator output for reading on the
power meter of:
Signal Generator
Frequency Calculation
100 MHz 200 mV
Power = Vin
200 MHz 350 mV
Power = Vin
6 Press the [Trigger] key, then press the Source softkey to set
the trigger source to External.
7 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.
8 Record the results as Pass or Fail in the Performance Test
