Measurements
Common To Serial And Parallel Signals - PREAMBLE
ERROR DETECTION: The analyser has a "hard" preamble
detector, which allows detection of a preamble error
on the 4 least significant bits. TEST OUTPUT LEVELS
FOR DISPLAY OF RESERVED CODES AND TRS ERRORS: 700 mV
at 75 Ohms.
Major Alarm
Threshold
SERIAL SIGNAL:
Signal absence or TRS word error frequency of more than
10 errors in 500 ms. PARALLEL SIGNAL: When clock/data
phase measurement shows clock phase to be outside the
range of ±11 nS. SECONDARY ALARM THRESHOLD: When one
parameter falls outside specifications. SERIAL LINK:
Adjustable from 2,400 to 19,200 Baud; delivered set
at 9,600 Baud. OTHER PARAMETERS: 8 bits, 1 start bit,
no parity.

270 Mb/s serial digital outputs at 75 Ohms.
Calibrated
errors on parallel signal - Level
errors can be introduced in the clock signal and on
the two most significant bits. PEAK-TO-PEAK LEVEL ERROR:
Vpp minimum = 0.25 V, ±0.1 V, Vpp nominal = 1.1 V, ±0.1
V. AVERAGE LEVEL ERROR: Vav min = 1.60 ±0.05 V, Vav
nom = 1.29 ±0.05 V, Vav max = -0.95 ±0.05 V. RIPPLE
VOLTAGE ERROR: 1V ±10% at 122 Hz or 7812 Hz. CLOCK/DATA
PHASE ERROR: -12 ns to +16 ns in steps of 4 ns, ±2 ns
precision for each step.
Errors
common to parallel and serial signals - Ability
to introduce reserved codes as well as errors in TRS
word and preambles. JITTER ERROR: 4 ±1 ns at 122 Hz
or 976 Hz.
