With Various Optional Software (See Buyer's Guide)
- Pulse Mask Compliance Testing
(Available only with Universal HD T1 E1 cards)
In T1 E1 transmission systems, signals are dropped, inserted, and accessed at the electrical level at a point called DSX patch panel or at some similar
point. To reliably receive, monitor, or access these signals, they must first conform to a standard that establishes parameters such as pulse width, rise time,
amplitude, allowable undershoot and overshoot. If the pulse meets the pulse mask, then a properly designed receiver should be able to decode the bits
transmitted.
GL's Universal T1 E1 Cards provides pulse mask compliance testing using Pulse Mask Display for both T1 and E1 applications. Software has been
developed to determine if the pulse shape fits within a "pulse mask" as specified by standards ITU G.703 and ANSI T1.102-1993. The software is available
in both visual and tabular formats. Tabular formats are convenient for automation and scripted test environments.
- Jitter Measurement
(Available only with Universal HD T1 E1 cards)
Jitter along with wander and frequency drift are major impairments of clocks in synchronous systems. Jitter is the time discrepancy between the time of
arrival of a clock pulse and its theoretical arrival time. GL's Jitter Measurement module allows evaluation of jitter on either a tick-by-tick or a cumulative basis.
Technically, cumulative jitter is of primary importance as network equipment must cope with the cumulative jitter. However, tick-by-tick measurements are
also presented in this module.
