Wait a few seconds for the measurement to settle (averaging is complete),
then note the Vp-p reading from the bottom of the display.
Vp-p = ______ mV.
Calculate the response using the following formula.
9
20 log
Correct the result from step 9 with any difference in the power meter
10
reading from step 7. Make sure you observe all number signs.
For example
Result from step 9 = 2.3 dB
Power meter reading from step 7 = 0.2 dB (REL)
True response = ( 2.3) ( 0.2) = 2.1 dB
The true response should be

and HP 54602B).
When you measure the bandwidth on channels 3 and 4, use the 0.1 V/Div
range.
