Please Note This chart is obsolete and does not conform to the updated ISO 12233:2014 standard. It has no slanted-edges and its wedges have an extremely limited frequency range. We strongly discourage its purchase. We recommend the ISO 12233:2014/2017 E-SFR chart for all testing, unless the old chart is specifically required. Based on EIA 1956 chart. Includes linear and pie shapes from 200 to 1000 lines, 10 step density tables, measurement bars and edge definition points. Email [email protected] for current lead time.
