Agilent/HP E1676A/B 51-2488 Mb/s SONET/SDH Transport Overhead Analyzer
The Agilent E1676A/B is a SONET/SDH Transport Overhead Analyzer for VXIbus systems. It can also be found associated with the manufacturers Keysight and HP (Hewlett-Packard). The model operates across a 51 to 2488 Mb/s data rate range. It functions as a message based instrument occupying a 3-slot C-size module. It measures 262 mm by 90 mm by 355 mm nominally. It weighs 4.3 kg or 9.5 lb nominally. The module connects to the backplane via P1 and P2 connectors per VXIbus Specification Revision 1.3.
The overhead analyzer maintains an active local bus connection to LBUSA and LBUSC. It draws current from six VXIbus dc voltage rails. The + 5 V rail supplies 9.5 A dc and 0.95 A dynamic current. The + 12 V rail supplies 0.5 A dc and 0.05 A dynamic current. The + 24 V rail supplies 2.2 A dc and 0.22 A dynamic current. The - 5.2 V rail supplies 8.8 A dc and 0.88 A dynamic current. The – 12 V rail supplies 0.1 A dc and 0.01 A dynamic current. The – 24 V rail supplies 0.2 A dc and 0.02 A dynamic current. The cooling for the module requires 4.5 liters per second airflow for a 10 °C rise. The rated pressure drop across the module reaches 0.2 mm H2O.
The operating temperature for the E1676A/B SONET/SDH Transport Overhead Analyzer ranges from 5 °C to 40 °C. The storage temperature for the unit ranges from – 20 °C to 60 °C. The humidity tolerance reaches up to 95 % relative humidity at 40 °C. The model meets CISPR11 Level A and EN50082-1 EMC standards. The timing for the transmitter outputs is derived from one of five sources. The internal source uses an oscillator locked to its internal reference. This oscillator runs at 155.52 MHz with a rated accuracy of ± 5ppm.
The reference clock source for the model operates at a nominal frequency of 155.52 MHz with a 50 % ±5 % duty cycle. This signal uses dc coupled 50 ohm impedance to – 2 V at ECL level through an SMA connector. The model supports Tributary Add Mode for clock and data input. The valid tributary data rates include 51.84, 155.52, and 622.08 Mb/s with ± 1 % tolerance.
