2 Set up the oscilloscope.
a Press the Save/Recall key, then press the Default Setup
softkey.
3 Change the signal generator output frequency as follows:
• For 300 MHz, 500 MHz, and 1 GHz models, set the
signal generator output frequency to 500 MHz
• For 100 MHz models, set the signal generator output
frequency to 100 MHz
4 Set the power meter Cal Factor % to the appropriate
value (500 MHz or 100 MHz) on the calibration chart on
the power sensor. If necessary, do a linear interpolation if
a 500 MHz or 100 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 625µW. (500mV
pp
= 176.78mV rms, Power

/50Ω = 625µW.)
6 Press the Trigger Edge 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
Record (see page 70).
If the test fails, see the "Troubleshooting" chapter. Then
return here.
