Press the Clear Display key on the scope, wait for the #Avgs value (top left corner of
screen) to return to 16 and then record the scope V rms reading in the Analog
Bandwidth - Maximum Frequency Check section of the Performance Test Record (Vout
@ 50 MHz). For all scope readings in this procedure, use the mean value in the
Measurements display area at the bottom of the screen.
10 Calculate the reference gain as follows:
Record this value in the Calculated Gain @50 MHz column in the Analog Bandwidth - Maximum
Frequency Check section of the Performance Test Record.
