This graph shows the transient intermoeuiatten uistonion (TIM)
spectrum. To measure this paramatar. a square wave or 3,15 kHz arid
a stne wave or is kHz are mixed and supplied to the input. The square
wave signal contains almost unlimited odd-number higher harmonics.
with oonrponenu at 9.54 kHz (third harmonic). 15.9 kHz (titth
harmonic). etc. When these components intermortuiate with the 154m:
signal. modulationprottucts show up at ireouencies where there is no
input signal. tor example at 5.45 kHl (15 kHz — 5.54 kHz). As the
reading oonnrnrs. there ere no distortion products at all above —r
which means that TM is less than 0.002%.

Thit graph shows the lnlermouulation distortion (IM) spectrum, as -
mammd by the IHF method. A IB-kHz and I 20ka signal are led to
the input. Any intenneduietion proouct oI thesa two signals would show
up at their iraquancy oillarenoe. to. 1 kHz. The reading continue that
such products are below «93 dB (00022?» Another intarmodulation
product would appear at 39 kHz. the sum or the two input signal
Imquefldes. Such distortion. Ivan II It cxlstad. would he

inconsequential because it is tar beyond the euoibie range. In the P-
102. this term at distortion Is also below -93 dB.
