Jitter application
Supports all manual and automatic measurements for jitter evalu-
ations.
Jitter measuring modes
Current values (continuous measurement): Peak-Peak, positive
peak, negative peak, RMS
Maximum values (gated measurement): Peak-Peak, positive peak,
negative peak
Logged values (repetitive measurements): Peak-Peak, positive peak,
negative peak
Phase hits
The instrument detects when the programmable threshold for
positive and negative jitter values is exceeded and the result indi-
cates how often the threshold was exceeded.
Jitter versus time
This function is used to record variations of jitter with time and
allows the positive and negative peak values, peak-to-peak values,
and RMS values to be displayed versus time. Duration is up to 99
days.
Automatic jitter measurements
Maximum tolerable jitter (MTJ)
The jitter module automatically determines the maximum jitter
amplitude tolerated by the DUT at selected jitter frequencies. The
maximum permissible jitter amplitude can be precisely determined
using a successive method. The module determines the exact limit
value. Several error sources are selectable. Standard tolerance
masks are available and can be edited.
