The monoscope test pattern was first used by broadcasters to provide a test pattern for receiver adjustments. It employed a special analog generator using an engraved CRT with precision deflection. Digitally synthesized generators followed but were prohibitively expensive. Leader now offers the 435B that features a digitally-generated monoscope pattern with wedges calibrated to read up to 1000 lines of TV resolution - the ideal source to test and offer proof of performance for high-performance TV monitors and VCRs. The monoscope pattern also offers perfect geometry for precise deflection size and linearity adjustments, provides resolution patterns in the corners to check corner focus, includes a 10-step grayscale to check tonal range and calibrated markers to check line-rate tilt (the cause of H streaking) and ringing. To round out the 435Bs value as a professional generator, it offers pulse and bar signal for critical chroma-delay checks, a line rate sweep for frequency response, a window signal for tilt/shading checks and a modulated staircase for linearity measurements. Both full field and SMPTE bars are included and color bars may be superimposed on the monoscope pattern. Monoscope, dot/crosshatch, window and character patterns may be inverted for a negative image
