EYE and Jitter/Frequency Patterns
Item Specification
- HD = 20 eyes displayed
• x5 - SD/HD = 3/5 eye displayed
- SD = 2 eyes displayed
- HD = 4 eyes displayed
• x10 - SD/HD = 3/10 eye displayed
- SD = 1 eye displayed
- HD = 2 eyes displayed
EYE amplitude display accuracy ± 5% @ 800mV input level
Measurement analog bandwidth
• 50 kHz to 2.25 GHz
• -3 to +1 dB relative to 750 MHz
Jitter high pass filters - 3 db response points
(For EYE and jitter / frequency displays)
• 10 Hz ± 2 Hz
• 100 Hz ± 10 Hz
• 1 KHz ± 100 Hz
•
(For jitter / frequency displays, option JEM, digitally filtered)
• 10KHz ± 500 Hz
• 100 KHz ± 5 KHz
• Jitter / frequency display follows selected eye pattern high pass filter
select (10 Hz, 100 Hz, or 1 kHz)
Jitter overshoot
≤ 20% of amount on input between high pass filter -3 db frequency to
10X all high pass filter bandwidths.
Intrinsic jitter
• ≤ 70 ps for HD
• ≤ 150 ps for SD
• Jitter displayed with ideal input, default display settings with cursor
measurement and 1 KHz filter selection, including crosstalk
Intrinsic wander
• ≤ 150 ps for HD
• ≤ 300 ps for HD
• With 10 Hz filter, observed over 1 hour after warm up
Lock-up time
≤ 1 second 1 KHz loop filter
≤ 5 seconds 10 Hz loop filter
Jitter display type
Option JEM only
Bar graph showing jitter magnitude
Jitter display range
Option JEM only
0 UI to 1.0 UI
Jitter frequency plot
Option JEM only
Displays a frequency histogram from the filter setting up to a
maximum frequency of 1 MHz or 5 MHz
Rise time measurement
