Squarewave
Frequency Range 2 Hz to SR / 6, in even integer sub-multiples of
SR
SMPTE/DIN Test Signal
Lower Tone Range 40 Hz to 500 Hz
Upper Tone Range 2 kHz to 0.47´SR
Mix Ratio 1:1 or 4:1 (LF:HF)
Noise Signal
White Pseudo-Random White, Rectangular PDF,
Bandwidth = 0.50´SR
Special Signals
Polarity Sum of two sinewaves phased for reinforcement
with normal polarity
Pass Thru Passes the embedded audio signal from the rear
panel Sync/Ref Input. Output Sample Rate (OSR)
must be within the range of 0.334 to 3.000 of the
Sync/Ref Input sample rate.
Monotonicity Staircase waveform of lowest 10 levels for D/A
linearity testing
J-Test Produces a maximum amount of data-induced
jitter on low-bandwidth transmission links
Walking Ones A single binary one value “walked” from LSB to
MSB
Walking Zeros A single binary zero value “walked” from LSB to
MSB
Constant Value
(Digital DC) 32-bit resolution when using triangular dither
Random Random binary states of all bits
Arbitrary Waveform (Multitone)
Sample Rates (SR) 65.536 kS/s, 131.072 kS/s, OSR (programmed
output rate), or ISR (selected input sample rate)

Frequency Range DC to 0.47´SR
Frequency Resolution Sample Rate / Length
Maximum Number of Tones (Length / 2) minus 1 [8191 with Length = 16384]
Dither
