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
4MHz.
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
4MHz.
Scale
Horizontal 1 Line, 2 Line, 1 Field, and 2 Field modes.
Vertical
1 UI/div, 0.2 UI/div, and v ariable 0.1 UI/div
to 2.5 UI/div.
Jitter Measurement Time 0.5 s
Approximately 10,000,000 independent
samples.

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
