   Keysight (Agilent) E4808A   Description / Specification:    
Keysight (Agilent) E4808A High Performance Clock Module, VXI

The Agilent E4808A Clock module (VXI) includes a PLL (Phase-Locked Loop) frequency generator to provide a system clock. Depending on the frequency chosen, the data modules can be clocked at a ratio of 1, 2, 4, 8, 16, 32, 64 or 256 times higher or lower than the system clock. External start/stop; The data running can be started by an external signal applied to the external input. With module E4832A there is also Stop and Gate mode. Ext. Clock/Ext. Reference; This input runs ParBERT 81250 synchronously with an ext. clock, or when a more accurate reference is needed than the internal oscillator. Usage of a continuous clock is necessary. Burst clock cannot be used as an external clock. Maximum external clock is 10.8Gbit/s for the E4808A. (Note: no improvement of jitter specifications will be achieved). Guided deskew; Individual semi-automatic deskew per channel. The deskew probe 15447A allows deskew on the DUT's (Device Under Test) fixture. Specifications. Frequency range (can be entered as period or frequency): 170 kHz to 675 MHz. Resolution: 1Hz. Accuracy: ±50 ppm with internal PLL reference. Zin/Termination voltage: 50 Ohm/-2.10 V to 3.30 V. Sensitivity/max levels: 200 mVpp/-3 V to + 6V for < 9.5Gbit/s, 300mVpp/-3V to+ 6V for > 9.5 Gbit/s. Input transitions/slope: < 20ns. Ext. input active edge is selectable. Input frequency/period Ext. Clock: 170 kHz - 10.8 GHz.

*This is a Web introductory price for one calibration of the Keysight (Agilent) E4808A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Data Rate
Data Rate is the maximum number of bits of information which can be transmitted per second, as in a data transmission link. Typically expressed as megabits per second (Mbps).

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

SONET
Synchronous Optical NETwork (SONET) is a fiber-optic transmission system for high-speed digital traffic. Employed by telephone companies and common carriers, speeds range from 51 Mbps to 40 Gbps. SONET is an intelligent system that provides advanced network management and a standard optical interface. Specified in the Broadband ISDN (B-ISDN) standard, SONET backbones are widely used to aggregate T1 and T3 lines. The European counterpart to SONET is the Synchronous Digital Hierarchy, and the term "SONET/SDH" is widely used when referring to SONET
