Selecting the Jitter Input Filter
You can choose from three types of jitter measurement high–pass
filters defined by ITU-T standards: wideband, highband, and
fullband. The passbands for the filters, shown in Figure 3–80, are
dependent on the signal or clock rate settings; the –3 dB frequencies
are described in the Specifications located in the Appendices at the
back of this book.
The ITU–T standard that applies to jitter input filters is contained in
G.823, Table 1, Measurement Filter Bandwidth.
