Sencore S310 Datasheet

S310 Digital Video Analyser Features:

Tests composite and component serial or parallel
digital video signals in both 525 and 625 line stan­dards

Direct readout LCD display and analog outputs
provide detailed analysis of all key signal parameters,
including: clock jitter, DC bias, TRS errors, reserve
code errors, presence of non-recommended lumi­nance or chroma levels, and much more

Contains user selectable alarm thresholds that can
provide instant warning of out-of-limit signal param­eters

All tests are performed to international stan­dards with easy to read pass or fail indicators
located on the front panel

A comprehensive CCIR 601 pattern genera
tor, Genlockable, with 34 different test pat­terns, two serial outputs, one parallel output,
and our exclusive signal error introduction
system

Optional software interface provides for
remote control of the unit, automated testing,
and exclusive data error logging capabilities

MEASUREMENT RANGE (Vrp): <1.5 V. Vrp FREQUENCY RANGE: 0 to 10 kHz. MEASUREMENT
RESOLUTION: 12 mV. TEST OUTPUT FOR MEASUREMENTS: Vpp and Vrp identical value to voltage
measured at 75 Ohms.

Jitter - PARALLEL SIGNAL JITTER RANGE: ±7.5 ns. SERIAL SIGNAL JITTER RANGE: ±1.5 ns. SE­RIAL SIGNAL JITTER RESOLUTION: 40 pS +10 pS with 10 m of cable. PARALLEL SIGNAL JITTER
BANDWIDTH: 1.4 kHz. PARALLEL TEST OUTPUT JITTER: 100 mV/ns at 75 Ohms. SERIAL TEST OUT­PUT JITTER: 300 mV/ns at 75 Ohms. MISCELLANEOUS - MON OUTPUT: 720 mV at 75 Ohms, DC com­ponent not transmitted. CLOCK OUTPUT: Parallel signal clock 400 mVpp at 75 Ohms, DC component not
transmitted.

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.
