SMPTE IMD waveforms (1:1/4:1/10:1)
SMPTE IMD is a signal which is the linear combination of two sine waveforms. The SMPTE
IMD waveforms conform to the SMPTE standard RP120-1983 for testing intermodulation
distortion. For SMPTE IMD 1:1, the lower frequency sine wave is linearly combined in 1:1
amplitude ratio with the upper frequency sine wave. For SMPTE IMD 4:1, the lower
frequency sine wave is linearly combined in 4:1 amplitude ratio with the upper frequency
sine wave. For SMPTE IMD 10:1, the lower frequency sine wave is linearly combined in 10:1
amplitude ratio with the upper frequency sine wave.
SMPTE IMD waveform mode is applicable for the analog, digital, and
Bluetooth
generator.
The waveform configuration for SMPTE 1:1 waveform is displayed as shown in
,
, and
for both the analog, digital, and
Bluetooth
generator
respectively.
