f When the Enter Measurement Info window appears, configure this measurement
as follows:
Source = Channel 1
Measurement Area = Entire Display
RMS Type = AC
7 Set the generator to apply a 50 MHz sine wave with a peak- to- peak amplitude of about
4 divisions.
• Use the following table to determine the approximate required signal amplitude.
The amplitude values in the table below are not absolutely required. If your
generator is unable to produce the recommended amplitude, then set the generator
to the highest value that does not produce a vertically clipped signal on the scope.
Table 3-1. Nominal Generator Amplitude Settings
8 Measure the input power to the scope channel and convert this measurement to Volts
RMS using the expression:
For example, if the power meter reading is 4.0 μW, then Vin = (4.0*10
-6
* 50Ω)
1/2
=
14.1 mVrms.
Record the RMS voltage in the Analog Bandwidth - Maximum Frequency Check section
of the Performance Test Record (Vin @ 50 MHz).
