Setting up Generator 5
• Amplitude: The random jitter Amplitude must be entered as an rms
(root mean square) value.
• Filter: The random jitter source is equipped with a 10 MHz high pass
and a 100 MHz and 500 MHz low pass filter to limit the spectral range.
Spectrally Distributed Random Jitter
Spectrally Distributed Random Jitter is composed of two jitter sources:
low frequency jitter and high frequency jitter. It is characterized by the
amplitudes of the low and the high frequency jitter.
Spectral Distributed Random Jitter is characterized by
•Amplitude LF
•Amplitude HF
It has the following parameters:
• sRJ State: Click this switch to enable the spectrally distributed random
jitter.
• SRJ Amplitude 1 (RMS) LF: This is the low frequency jitter amplitude as
rms value.
• SRJ Amplitude 2 (RMS) HF: This is the high frequency jitter amplitude
as rms value.
• sRJ Low Pass Filter: The spectrally distributed random jitter is
equipped with a 100 MHz low pass filter to limit the spectral range,
which can be enabled by pressing the corresponding switch.
