9 Change the signal generator output frequency according to the maximum
frequency for the oscilloscope using the following:
• 6GHz Models: 6GHz
• 4GHz Models: 4GHz
• 2.5 GHz Models: 2.5 GHz
• 1GHz Models: 1GHz
10 Referencing the frequency from step 9, set the power meter Cal Factor % to the
frequency value on the calibration chart on the power sensor.
11 Set the oscilloscope sweep speed according to the following:
• 6 GHz Models: 100 ps/div
• 4 GHz Models: 100 ps/div
• 2.5 GHz Models: 100 ps/div
• 1 GHz Models: 500 ps/div
12 Note the oscilloscope AC RMS - FS(1) reading at the bottom of the screen.
13 Note the reading on the power meter and covert to Vrms using the expression:
14 Calculate the response using the expression:
Example If:
Pmeas
1_MHz
= 892 uW
AC RMS - FS(n)
1MHz
= 210.4 mV
Pmeas
max_freq
= 687 uW
AC RMS - FS(n)
max freq
= 161.6 mV
Then after converting the values from the power meter to Vrms:
15 The result from step 14 should be within -3.0 dB. Record the result in the
Performance Test Record (see page 52).
