How to Operate Your Instrument
SDI Status Display
The SDI Status display shows the current status of the SDI signal. This display shows both the Jitter1 and Jitter2
thermometers. Additionally, a Cable Loss thermometer indicates the signal loss due to cable length. Use the Settings menu
in the Eye display to configure the instrument for the cable type and length of your installation. With Option Phy installed, the
SDI Status Display also shows the eye amplitude, eye rise time, eye fall time, and eye rise-fall delta measurement values. To
view the SDI Status display, the instrument must have Option Eye or Phy installed.
There are two Jitter Thermometers in the SDI Status display because there are two independent clock recovery circuits in the
instrument and each circuit can be set to a different bandwidth. Note that the Eye and the Jitter displays share these two
circuits. The upper two tiles use clock recovery circuit one, and the lower two tiles use clock recovery circuit two. This means
that any combination of Eye and Jitter displays in the top two tiles will have the same bandwidth, but any combination of eye
and jitter in the left or right two tiles can have any two bandwidths from the list of possible choices.
Elements of the SDI Status Display:
1. Jitter1 and Jitter2 thermometers and
readouts:
The Jitter Thermometer uses
a colored bar to indicate the relationship
of the jitter measurement to the Jitter
Amplitude limit (which is user adjustable
from the Eye or Jitter display).
2. Cable Loss Thermometer and
readouts:
The Cable Loss Thermometer
works just like the Jitter Thermometer,
using color to indicate the relationship of
the measurement to the Cable Loss limit
(which is user adjustable from the Eye or
Jitter display).
3. Eye Measurements
: With Option Phy
installed, a set of eye measurements
are displayed below the Cable Loss
measurements.
