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.
