23 Calculate the gain at the maximum frequency using the expression and
record it in the “Performance Test Record” on page 144:
For example, if (Vout @ Max Frequency) = 371 mV, (Vin @ Max
Frequency) = 427 mV and Gain @ 1 MHz = 0.993, then:
Record this value in the Calculated Gain @Max Freq column in the
Analog Bandwidth - Maximum Frequency Check section of the
“Performance Test Record” on page 144. To pass this test, this value
must be greater than -3.0 dB.
24 Move the power splitter from channel 1 to channel 2 and repeat steps 3
through 24 using channel 2 as the source.
