Procedure:
A. Preset the 3314A.
B. Set the 3314A as follows:
ЕТЕППЕН au caque cea ЫРА Deka SEX КЫЗ 20Hz
Amplitude ..........................-... 10Vp-p
C. Connect the 50 Ohm Feedthrough Termination to
the 3314A's Main Output. Connect the 5000 Feed-
through Termination to the 3314A's X3 Output.
D. Connect the spectrum analyzer's IMQ input to the
3314A's X3 Output. Set the spectrum analyzer to measure
the fundamental and at least seven harmonics. Use the
Marker function to verify that the level of the largest har-
monic is more than 53dB below the fundamental.
E. Repeat step D for 3314A frequency settings of
50kHz and 1MHz. The largest harmonic should be more
than 53dB below the fundamental at 50kHz, and more
than 38dB below at ІМН2.
