“DIM100” or “DIM30”
“DIM-B”
“DIM-B8”
Mix Ratio 4:1, square to sine, peak-peak
Amplitude Range <60 V to 75.4 Vpp, balanced;
<30 V to 37.7 Vpp, unbalanced.
Amplitude Accuracy ±0.10 dB [±1.2%]
Residual IMD
1,2,3
–95 dB [0.0018%]
Multitone, Wave File Playback
Sample Rate Range (SR) 8 kS/s to 108 kS/s, and
175 kS/s to 192 kS/s
Operation from 109 kS/s to 175 kS/s is
possible, but with degraded flatness
Maximum File Size 32M Sample
Amplitude Range 0 to 45.2 Vpp, balanced;
0 to 22.6 Vpp, unbalanced.
".Wav" file must peak at digital full scale
to obtain selected amplitude.
Flatness (1 kHz ref)
SR = 175 kS/s to 192 kS/sec Typically <0.012 dB to 20 kHz
SR = 8 kS/s to 108 kS/sec Typically <0.04 dB to 20 kHz;
max frequency limited to 0.45*SR
Spurious Content Typically <–110 dB
Output Equalization
Arbitrary 30-pole output filter Filter cannot be applied to special wave-
forms square and DIM.
Source Resistance (Rs)
Balanced Selectable 40 ±1.5%, 100 ±1%,
150 ±1%, 200 ±1%, or
600 ±1%.
Grounded, symmetrical
Unbalanced Selectable 20 ±2%, 50 ±1.5%,
75 ±1.2%, 100 ±1%, or
600 ±1%.
Electronically floating, 0.3 Vpk max;
bnc shield to ground 10-17 || 22nF
Common Mode Test Same as Balanced selections, or
10 Unbalanced per IEC-60268.
Max Output Current
Typically >80 mA peak, 50 mA dc
Reverse Overload Protection
Up to 1A or 30 W, whichever is less
