Kikusui COS6100M

The Kikusui COS6100M is a 100 MHz, 2-channel analog oscilloscope engineered for electronics testing, circuit analysis, and educational use. Its 6-inch rectangular CRT with red internal graticule and 20 kV acceleration voltage delivers bright, clear waveforms. The instrument provides flexible vertical sensitivity from 5 mV/division to 5 V/division, with 1 mV/division capability via x5 magnification. Sweep rates span 20 ns/division to 0.5 seconds/division across 23 calibrated steps, supported by x10 magnification down to 2 ns/division. Multiple coupling modes DC, AC, GND, LF REJ (below 15 kHz), and HF REJ (above 50 kHz) - enable signal conditioning for diverse measurement scenarios. The trigger system features DC and AC triggering with sensitivity thresholds, TV sync separation for video applications, and level-lock circuitry that stabilizes triggering on most waveforms. Holdoff control remains active in B END'S A mode. X-Y display mode is available via selector switch. The internal calibrator outputs 1 V at ±1% accuracy and 200 mV at ±2% accuracy. Input impedance is 1 MΩ ±1% with 20 pF ±2 pF capacitance. Sweep time accuracy reaches ±3% over 0°C to 55°C; magnified sweeps maintain ±5% accuracy. Linearity is ±0.25 minor divisions or better. The 11.4 lb instrument measures 12.20 W × 5.91 H × 15.75 D inches, making it suitable for laboratory and field deployment.
