Making Measurements
Measuring Jitter Tolerance
| Measuring Jitter Tolerance |
Description: | The jitter auto tolerance feature provides jitter tolerance measurements |
| within the relevant |
| Bellcore |
| Jitter is generated at a range of frequencies within the mask and an |
| error measurement is made. If no errors occur (PASS), the jitter |
| amplitude at that frequency point is increased until errors occur (FAIL) |
| or the maximum jitter amplitude is reached. The highest jitter |
| amplitude at which PASS occurs is plotted on the graph as the Jitter |
| Tolerance for that jitter frequency. |
TIP: | The transmitter and receiver can be set to different rates to allow testing |
| across multiplexers, for example transmitter set to |
|
HOW TO: Make the Measurement
1If you are performing jitter tolerance on the DSn signal, set up the DSn transmit and receive interfaces. See “Setting DSn Transmit Interface” page 2 and “Setting DSn Receive Interface” page 15.
