Specifications
The following tables list the specifications for the Tektronix WVR7200 Waveform
Rasterizers. 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 °C to +40 °C. The rated accuracies
are valid when the instrument is calibrated in an ambient temperature range of
+20 °C to +30 °C.

Pulse-to-bar ratio 0.995:1 to 1.005:1 on
appropriate Sine Squared or Blackman 2T

A sine-squared pulse near Nyquist is not
band-limited and so inherently has ringing
much larger than the waveform rasterizer
filter. A three term Blackman pulse with the
same HAD has much less inherent ringing,
so it is a better choice for most testing. See
