The J7115B is a jitter noise generator in the J7000B series that produces additive white Gaussian noise (AWGN) to model random jitter (Rj) for high-speed digital system testing. It operates from 10 MHz to 5 GHz with an output noise power of -3 dBm and a flatness of ±2.5 dB. The device features a 7-inch touch-screen display, SMA female connectors, differential inputs and outputs, and supports noise attenuation from 0 to 63 dB in 0.1 dB steps. It is designed for BER and jitter testing of serial interfaces including PCIe and 100 Gig Ethernet, and can be controlled via Ethernet or optional GPIB. The instrument measures 17.22 in. wide, 6.30 in. high, and 19.5 in. deep, and operates on 115 VAC, 60 Hz with a temperature range of -10°C to +65°C.
The J7000B jitter noise generator generates additive white Gaussian noise (AWGN) with a large crest factor to model “real world” random jitter. This random jitter is commonly referred to as Rj in the industry accepted jitter hierarchy model and managing Rj is critical to the performance and capability of high-speed communication busses and devices. Today’s high-speed digital circuit designers are challenged with narrow jitter tolerances to deliver high data rates with low bit error rate (BER). Designing a system that is not only compliant to industry specifications but also robust enough to handle jitter and maintain an acceptable bit error rate is a never ending challenge and only gets harder as frequency and data rate increase.
