J7000A Data Sheet
Application Notes
|
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 Noise Com 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.
