9 Change the signal generator output frequency according to
the maximum frequency for the oscilloscope using the
following:
• 1 GHz Models: 1 GHz
• 500 MHz Models: 500 MHz
• 300 MHz Models: 300 MHz
• 100 MHz Models: 100 MHz
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:
• 1 GHz Models: 500 ps/div
• 500 MHz Models: 1 ns/div
• 300 MHz Models: 2 ns/div
• 100 MHz Models: 5 ns/div
12 Note the oscilloscope Std Dev(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
Std Dev(n)
1MHz
= 210.4 mV
Pmeas
max_freq
