Specifications

The tables in this appendix list the specifications for the Tektronix WVR610A &
WVR611A Waveform Rasterizers. Items listed in the Performance Requirement
column are generally quantitative, and are either tested by the Performance
Verification procedure in the Service Manual or are guaranteed by design. 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+50_C. The rated
accuracies are valid when the instrument is calibrated in an ambient temperature
range of +20 _Cto+30_C.
