Data signal quality evaluation apparatus |
摘要 |
When an operating unit is operated to designate an arbitrary width W and an arbitrary angle &thetas;, a mask region limiting unit limits the effective range of a reference mask set for compliance measurement of the data signal to be evaluated by a reference mask setting unit to the range determined by the designated width and angle and displays the limited effective range on a display unit. When the mask region limiting unit limits the effective range of the reference mask, a quality evaluating unit performs compliance measurement and quality evaluation for the limited effective range in operative association with the limitation of the effective range. |
