AC Amplitude Accuracy-Output 1
4. On the Multifunction Synthesizer, key in AMPTD 8 V. Set the oscilloscope’s input impedance to
50 ohms or terminate the input in 50 ohms using a tee. Set the oscilloscope’s vertical sensitivity
to 1 V/division. Adjust the vertical position of the dc trace to coincide with the second graticule
line from the top
of the screen.
5. On the Multifunction Synthesizer, key in WAVE FORM ’L. Set the frequency indicated in
the following table. (The amplitude is
to remain the same as set in step 4, that is, 8V.) For
each setting, adjust the oscilloscope’s time scale to obtain a useable display and note the peak
amplitude relative
to the second graticule line. The peak amplitude should be within the limits
listed in the table.
