1. Results Calibration The Eye BERT 10G utilizes optical power and temperature measurements as reported by the XFP module therefore the accuracy and calibration of these measurements is entirely dependent upon the XFP module The Eye BERT 10G pattern generation detection and timing parameters are all based on digital circuitry within the module and therefore require no calibration www spectronixinc com Page 6 Eye BERT 10G User s Guide V 1 0 Letter of Volatility The Eye BERT 10G contains both volatile and non volatile memory The Eye BERT 10G firmware application and configuration settings are stored in non volatile memory and program variables and settings are stored in volatile RAM which is cleared upon power down The user has no means of altering the program memory without opening up the unit and reprogramming the device using a special programming adapter The unit can be forced to its factory default state by following the Memory Clearing Factory Settings instructions above www spectronixinc com Page 7 Eye BERT 10G User s Guide V 1 02. After starting the application press the Connection button to automatically connect to the Eye BERT upon successful connection this button will turn green and the fields will begin to update The user may also choose to select a specific COM port number from the drop down list this is useful when there is more than one Eye BERT connected to a computer After communication is established the Connection indicator will turn green the screen www spectronixinc com Page 3 Eye BERT 10G User s Guide V 1 0 will be populated with the current measurements and the XFP model and serial numbers will be displayed in the application header A Eye BERT Micro 10G HFCT 721XPD M6479FW5 V1 0 BAN SE Eye BERT Micro 10G HFCT 721XPD M6479FW5 V1 0 BERT BER BER 8 428E 13 10 7cm mmm 0 000E 00 10 7 mm Errors 2 000E 00 22 4 dBm Errors 0 000E 00 2 Aapm Count 0 000E 00 Count 2 373E 12 1310 00 nm mee 1310 00 nm Read xFP mm Read XFP Time 0d 00 03 42 C4 amet A P Time 0d 00 00 00 39 7 c Spectronix Ero Hoy 38 8 c www spectronixinc com spectronixinc col Bitrate Gbps Gaon ia Gbps Bitrate Gbps custom ta Gbps 9 95328 iiare Ales 10 51880 10 70920 11 04900 11 09570 11 20700 11 31760 9 95328 10 3125 10 51880 10 70920 11 04900 11 09570 11 20700 11 31760 Pattern Generator and Checker Pattern Generator and Checker PRBS 7 2 1 PRBS 231 1 DCD Repeat Custom Ox AAAAAAAAAAAAAAAA 1
3. Memory Clearing Factory Settings The Eye BERT 10G stores configuration settings in non volatile memory in some cases it may be desirable to restore the factory default settings To do this while the unit is powered off press and hold the Power Select button and Up arrow key simultaneously until the memory clearing screen is displayed then follow the directions on the screen This will reconfigure the unit to its factory default settings Computer GUI Operation In order for Windows to recognize the Eye BERT 10G the USB driver must first be installed after which the Eye BERT 10G appears as an additional COM port on the computer Currently Windows XP Vista and 7 are supported 1 Copy the file cdc_NTXPV764 inf from the supplied CD to the hard drive Connect power to the Eye BERT 10G using the supplied 5VDC adapter Plug the Eye BERT 10G into a free USB port When the hardware installation wizard asks for the driver location browse to the cdc_NTXPV764 inf location on the hard drive and complete the installation Note on some operating systems such as Window 7 manual USB driver installation may be necessary If the hardware installation wizard fails go to My Computer gt Properties gt Hardware gt Device Manager and find the Spectronix or SERIAL DEMO entry under Other Devices and select Update Driver At this point you will be able to browse to the location of
