Table 33: Jitter Display characteristics (Option PHY) (cont.)
Characteristic Performance requirement Reference information
Resolution 0.01 UI
Jitter Waveform
Amplitude Error, typical Error for jitter frequencies between HPF
setting and 5x HPF setting due to loop
peaking, maximum of 1.5 dB.
HD at 10 Hz HPF Within 0.4 UI + 10% of reading for jitter
frequencies from 5x bandwidth selection to
4 MHz.
HD at 100 Hz to 100 kHz
HPF
SD at All HPF Settings Within 0.1 UI + 10% of reading for jitter
frequencies from 5x bandwidth selection to
4 MHz.
Scale
Horizontal 1 Line, 2 Line, 1 Field, and 2 Field modes.
Vertical 1 UI/div, 0.2 UI/div, and variable 0.1 UI/div
to 2.5 UI/div.
Jitter Measurement Time 0.5 s
Approximately 10,000,000 independent
samples.
Table 34: Signal level and cable length detector characteristics
Characteristic Performance requirement Reference information
Source Level Detector
Measurement Accuracy,
typical 40 mV at 800 mV level, 0 to 100 m Belden
8281 cable.
Measurement Resolution,
typical 10 mV
Measurement Dynamic
Range, typical ± 50% from 800 mV.
Cable Length Detector
Measurement Error
15 m 10% of the reading for the cable type. Requires clean SD signal with rise time less
than 1 ns for full accuracy. Excessive ringing
or slower rise time may appear as increased
cable length.
Measurement Resolution 2 m
Measurement Range, typical Cable loss range of 0 to 40 dB at ½ serial
bit rate. Equivalent to:
HD: 0 to 120 m Belden 8281
SD: 0 to 400 m Belden 8281
