SMPTE (DIN) IMD Function with option IMD
Test Signal Compatibility
Any combination of 40 – 250 Hz (LF) and 3 kHz
– 20 kHz (HF) tones, mixed in any ratio from
0:1 to 8:1 (LF:HF)
IMD Measured
Amplitude modulation products of the HF tone.
-3 dB measurement bandwidth is typically
20Hz - 750Hz
Measurement Range
<0.0025% – 20%
Accuracy
±1 dB per SMPTE RP-120-1983, DIN 45403
Residual IMD (Vin ≥200mV)
9
≤0.0025% [-92 dB], 60 + 7 kHz or 250 + 8 kHz
Minimum Input
100 mV
Ratio Function
Measurement Range
-80 dB to +100 dB, 0.01 dB resolution
Accuracy
±0.1 dB, 20 Hz – 20 kHz
Minimum Input
Mode 1 10 mV [-38 dBu], denominator signal
10 µV [-98 dBu], numerator signal
Mode 2
10 µV [-98 dBu], denominator signal
10 mV [-38 dBu], numerator signal
Note 7 Uses the 1/3 octave bandpass filter to enhance the measured range in the presence
of wideband noise. Alternate (interfering) channel input must be ≥5 mV.
Note 8 For fully specified performance. Usable with inputs as low as 10 mV. Readings are
disabled for inputs below approximately 7–8mV.
Note 9 System specification including contribution from generator.
