Table A-20: Generator Signals
Capabilities Description
Generated Signals
Sine A single sine-wave tone with variable amplitude
and frequency. The amplitude or frequency or
both may be swept or stepped to provide a wide
range of sinusoidal test signals.
Tone Burst
Width
Period
A sine-wave burst tone with variable amplitude,
frequency, burst width, and burst period
10 to 100000 cycles, resolution 1
64 to 100064 cycles, resolution 1
The generator converts the width time parameter
into the nearest number of cycles of sine wave to
generate.
SMPTE/DIN type IMD
Amplitude Ratio
Variable Frequency
Fixed Frequency
A two-tone intermodulation signal with one tone
variable in frequency
0.01 to 8
3 kHz to 18 kHz, resolution 0.1
40 Hz and 500 Hz
With appropriate parameter choices this signal
can be used in a SMPTE or DIN intermodulation
distortion test.
CCIF type IMD
Amplitude Ratio
Center Frequency
Frequency Spacing
A two-tone intermodulation signal. Both tones are
typically swept in tandem with a constant frequen-
cy separation.
0.01, 100
2.5 kHz, 19 kHz
80 Hz, 1000 Hz
With appropriate parameter choices, this signal
can be used in a CCIF intermodulation distortion
test.
Shaped Noise A periodic pseudo-random noise signal with a
specified spectral distribution
The available colors of the noise are white and
pink.
