The following tables list the specifications for the Tektronix WFM6100,
WFM7000, and WFM7100 Waveform Monitors with Option FP installed. Items
listed in the Performance Requirement column are generally quantitative, and
can be tested by the Performance Verification procedure in Section 2 of this
manual. Items listed in the Reference Information column are useful operating
parameters that have typical values; information in this column is not guaranteed.
The specifications listed in the Electrical Specifications portion of these tables
apply over an ambient temperature range of +0 _Cto+40_C. The rated
accuracies are valid when the instrument is calibrated in an ambient temperature
range of +20 _Cto+30_C.

of peak--to--peak jitter. Jitter derived from
demodulated recovered clock as described
in SMPTE RP192 2003. If Opt. PHY is
installed, then Jitter Waveform can also be
displayed
High-Pass Filter Settings Can be set to 10 Hz, 1 kHz, 10 kHz, or
100 kHz
High pass filter has type--3 response for
low frequency rejection of 60 dB/decade
below the filter setting. High pass filter also
applies to digital readout, jitter waveform
and Eye diagram display, but not the
reference clock output. There are two
independent Jitter demodulators which
may be configured with different loop
bandwidths. One is applied to the upper
two tiles of the display, and the other
applies to the lower two tiles
High-Pass Filter Attenuation Accuracy Frequency at which response is --3dB is
within 10% of nominal
High--Pass Frequency Response also
applies to readout and jitter waveform
High-End Frequency Response, Typical --3dBat >5MHz
Applies to digital readout, jitter waveform,
and reference clock output
