Chapter 4: Testing Performance

Analog Bandwidth - Maximum Frequency Check

g When the RMS voltage measurement setup window is displayed, configure this measurement

as follows:

Source = Channel 1

Measurement Area = Entire Display

RMS Type = AC

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

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 W, then Vin = (4.0*10

-6

* 50)

1/2

= 14.1 mVrms.

Record the RMS voltage in the Analog Bandwidth - Maximum Frequency Check section of the

Performance Test Record (in the Vin @ 50 MHz column).
