UFX7000 Noise Generator The UFX7000A Series instruments provide Broadband Gaussian noise with superior flatness. The output power can be attenuated up to 127 dB in 1 dB steps, and several connector types are available. |
 |
PNG7000 Analog Noise Generator The PNG7000A Series instruments generate white Gaussian noise and provide a summing input to control signal-to-noise (SNR) or carrier-to-noise (CNR) for bit-error-ratio (BER) testing. The output can also be used as a source for Jitter applications. |

J7000 Jitter Noise Generator The J7000A Series instruments high crest factor output is used as a random jitter source for serial data bus applications, including PCI Express Gen I & II, Serial ATA, and Fiber Channel. The noise source is designed for the PCI-SIG total jitter (Tj) model serial data application, but can be used for any random jitter noise application. |

JV9000 Adjustable Vcc Noise Generator for PSRR Analysis Noise on Ground and Vcc traces is becoming an increasing concern of component designers, manufacturers and system users. Whether developing or operating highly accurate PLL or clock circuits, A/D D/A converters and other linear analog circuits for precision operations or such that are reliant on precise threshold functions, Ground and VCC noise can significantly influence overall system functionality. Even high-speed digital circuits are not immune against this kind of noise and should be tested for Ground and VCC noise related effects on data jitter and data integrity. |

CNG-EbNo SNR Noise Generator The UFX-EbNo is a fully automated precision signal to noise generator that sets, and maintains a highly accurate ratio between a user supplied carrier and internally generated noise, over a wide range of signal power levels and frequencies. The internal power meter provides repeatable SNR waveforms for accurate signal generation. |
 |
DNG7500 Digital Noise Generator The programmable DNG7500, generates pseudo-random noise and CW signals for RF, Microwave, and digital applications. It can provide up to a 70 MHz wide RF output to emulate real-world noise and interference conditions. The user can create many complex waveforms, including digital notches, and burst pattern waveforms. |
 |
GPS7500 Noise & Interference Generator The programmable GPS7500 Noise & Interference Generator is capable of generating up to a 40 MHz wide noise or interference band for GPS receiver susceptibility testing. |
 |
NC6000A/8000A Series The NC6000A and NC8000A Series instruments are designed for general-purpose noise applications on the bench, or in a rack test station. The manual controls make it simple to operate and reduce test set up time. Standard units can be modified for specific customer requirements. Please consult the factory for pricing and availability of these requests. |
