Specifications
This chapter contains specifications for the Te ktronix WVR6020, WVR7020, and
WVR7120 waveform rasterizers. Items listed in the Performance Requirement
column are ge
nerally quantitative, and are either tested by the Performance
Verification procedure 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 °C to +50 °C. The rated accuracies
are valid when the instrument is calibrated in an ambient temperature range of
+20 °C to +30 °C and has been operating continuously for at least 20 minutes
within this range.
The characteristics are divided into the following sections:
Common Characteristics
High Definition (HD) Characteristics
Standard Definition (SD) Characteristics
Options Characteristics
Common Characteristics
The characteristics in this section are common to the WVR6020, WVR7020,
and WVR7120 Waveform Rasterizers.
