Extended Sinusoidal Jitter & SSC Generation
Option XSSC for the BERTScope family adds capabilities beyond those in the
BERTScope S models, to make your testing easier.
Existing telecom standards and some emerging serial bus standards have
sinusoidal jitter (SJ) requirements for receiver
interference tolerance testing that go
beyond the standard
capabilities of BERTScope S models. Option XSSC significantly
increases the low frequency SJ range, and enhances the
available Spread Spectrum
Clocking (SSC) modulation.
Option XSSC meets or exceeds the requirements of existing SJ tests,
and is able to apply SSC simultaneously with high frequency SJ appropriate for all
standardized test cases. The capabilities of the rear panel reference input and output
are enhanced, allowing the BERTScope to be frequency locked to a number of rates from
10 MHz to 200 MHz and able to supply a high quality reference output appropriate for
several common system clocks.

- Higher amplitudes of sinusoidal jitter at
lower modulation frequencies allow full compliance testing of jitter
tolerance and transfer, as well as generation with BERTScope
DCRJ for SONET/SDH. In addition, full
jitter tolerance compliance testing for XAUI, XFP telecom, and CEI
telecom ingress and egress is provided.
- Broader range of frequencies and amplitudes of SSC modulation
capabilities.
- Expanded reference clock frequencies:
- 10, 100, 106.25, 133.33, 156.25, 166.67, 200 MHz,
for phase locking to other systems or supplying a clock for target devices.
- Front panel clock and sub-rate clock outputs are phase
modulated when low frequency SJ is enabled; rear panel reference interfaces are not.
