18 Calculate the reference gain as follows:
Record this value in the Calculated Gain @ 1 MHz column of the
“Performance Test Record” on page 144.
19 Change the signal generator frequency to the value for the model being
tested as shown in the table below.
20
Change the oscilloscope time base to the value for the model being tests
as shown in the table above.
21 Using the Vpp reading, calculate the Vrms value using the following
expression and record it in the
“Performance Test Record” on page 144:
For example, if Vpp = 1.24 V:
22
Using the power meter reading, convert this measurement to Volts RMS
using the expression and record it in the
“Performance Test Record” on
page 144:
For example, if Pmeas = 3.65 mW:
