PERFORMANCE TESTS
3. Set the oscillator frequencies as indicated below. For each frequency setting, perform the following procedure:
a. Set the second oscillator level to minimum. Note the level of the output of the low-distortion oscillator on the external voltmeter.
b. Set the low-distortion oscillator amplitude to OV. Adjust the second oscillator’s level for the same
reading as in step a.
c. Decrement (that is, attenuate) the second oscillator’s output level as indicated.
d. Set the low-distortion oscillator level to 6V. The display on the Distortion Analyzer should read
within the limits indicated.
