Delay Control Input - Procedures
N O T E
The following procedure does not apply to Serial BERT on which the calibrated and
integrated jitter injection option J10 is installed. For such instruments refer to
“Jitter Setup - Procedures” on page 407.
To set up a jitter tolerance test on an instrument without option J10:
1
Press PG Data Setup in the PG Setup menu.
2
Disable the Delay Control In port by clearing the Delay Control Input checkbox.
3
Connect the device that supplies the jitter signal to the Delay Control In port.
4
Enable the port again by selecting the Delay Control Input checkbox.
T I P
While monitoring the BER you can use this checkbox to switch jitter on and off and
view the effect on the BER.
Delay Control Input - Reference
This checkbox in the PG Data Setup window is used to disable or enable the Delay
Control In port, where you can supply an external signal to add jitter to the output
signal.
