User guide

This opens a window which allows you to set all parameters available for the
given jitter type.
6
Specify the following parameters:
– Standard
– Sweep Time
– Nr. of Steps
– Step Distance
For more information on parameters, see “Periodic Jitter 2 – Variable Amplitude
Sweep Parameters” on page 424.
7
Observe the consumption of delay line capacity indicated by the delay line
markers. Ensure that the total jitter remains within the margins of the chosen
delay line.
8
Return to the overview display by pressing either the Close button, the Edit
button of this jitter source or the Edit button of the next jitter source you want
to change
9
Proceed with the next jitter type you wish to add.
N O T E
When you activate an External jitter source you will find that this apparently
consumes the whole free capacity of the delay line (at the right-hand side of the red
bar).
But this is just an indication. You can still add or change internal jitter components.
The external jitter range is automatically updated when you add, change, or switch
off one of the internal sources.
