   Keysight (Agilent) E4805B   Description / Specification:    
Keysight (Agilent) E4805B 675 MHz Central Clock Module, VXI

The Agilent E4805B 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 2.7 GHz for the E4805B. (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): 1kHZ 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: 400 mVpp/-3 V to + 6 V. Input transitions/slope: < 20ns. Ext. input active edge is selectable. Input frequency/period Ext. Clock: 170 kHz - 2.7 GHz.

*This is a Web introductory price for one calibration of the Keysight (Agilent) E4805B. 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.

Accuracy
Accuracy is the degree of closeness of measurements of a quantity to that quantity's actual (true) value.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Receiver Sensitivity
Receiver Sensitivity is the optical power required by a receiver for low error signal transmission. In the case of digital signal transmission, the mean optical power is usually quoted in Watts or dBm (decibels referred to 1 milliwatt).
