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.
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. A key feature of this
instrument is its low distortion signal path that sums the user-supplied
signal with the internal precision white noise source. Standard units can
be modified for specific customer requirements. Please consult the factory
for pricing and availability of these requests.
* Units above 2 GHz have 79.9 dB attenuation
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. In standby
mode, the output RF switch is terminated into a 50-ohm load, while in the
"on" state it is directed to the output connector. The UFX7000A Series
flexible architecture allows several options, including an internal
combiner, 0.1 dB attenuation steps, and internal switches for up to 4
filter paths. Standard units can be modified for specific customer
requirements. Please consult the factory for pricing and availability of
these requests.
* Units above 2 GHz have 79.9 dB attenuation
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. The random nature
of this output is designed to model real world electrical noise commonly
found in digital electrical circuits. The summing input can control
signal-to-noise (SNR) or carrier-to-noise (CNR) for bit-error-ratio (BER)
testing similar to other Noisecom instruments. The signal path has a
nominal insertion gain of 0 dB, with very low amplitude and phase ripple.
Standard units can be modified for specific customer requirements. Please
consult the factory for pricing and availability of these requests.
* Units above 2 GHz have 79.9 dB attenuation
Multiple Operating Modes Custom configurations Direct Display of Eb/No, C/N, C/I or C/No Bit Rate Entry of 1 bps to 999 Mbps and above Variable output power
Precision S/N, C/N, C/No, C/I and Eb/No Measurements. Noisecom has launched its new CNG-EbNo series of precisionsignal-to-noise generators. These analyzers are designed for Carrier-to-Noise (C/N), Carrier-to-Noise density (C/No), Signal-to-Noise (S/N), Carrier-to-Interferer (C/I) and Bit Energy-to-Noise density (Eb/No) analysis. The instruments are used for satellite communications, cable TV, telecommunications, and many other critical applications that demand accuracy and repeatability in the analysis of data transmission systems. Our new CNG-EbNo series succeed Noisecom’s well-known UFX-EbNo products. The CNG-EbNo is an essential instrument for applications requiring high data rates that have to be transmitted reliably under challenging circumstances, such as weak signals embedded within high adjacent noise levels. The CNG-EbNo is a truly versatile instrument. It not only provides a variety of highly accurate noise ratios, it also serves as a true RMS power meter and can be utilized as a precision noise generator. CNG-EbNo analyzers are available in a variety of off-the-shelf frequency bands. Noisecom also provides customized frequency bands. The analyzer is available in 50 or 75 ohms impedance versions. Signal input range is -55 dBm to +5dBm. During bit energy-to-noise density analysis, CNG-EbNo analyzers calculate noise density automatically based on user specified bit rates, which can range from 1 bps to 999Mbps. The new CNG-EbNo comes with a convenient touch screen display that allows easy setting of all measurement parameters.
