DUAL TRACE ANALOG OSCILLOSCOPE 20MHZ, REK MOS620CH

Vertical Axis Sensitivity: 5mV~5V/DIV, 10 steps in 1-2-5 sequence Vernier Vertical Sensitivity:To 1/2.5 or less of panel-indicated value. Frequency bandwidth: DC~20MHz & DC~40MHz AC coupling:Low limit frequency 10Hz. Rise time:Approx. 17.5nS for 20MHz Approx. 8.75nS for 40MHz Input impedance: Approx. 1M ohm//Approx.25pF DC balance shift: Adjustable on panel Linearity: ≤ ±0.1 DIV of amplitude change when waveform of 2 DIV at graticule center is moved vertically. Vertical modes:CH1:CH1 single channel.CH2: CH2 single channel. DUAL:CH1 and CH2 are displayed. ALT or CHOP selectable at any sweep rate. ADD:CH1+CH2 algebraic addition. Chopping repetition frequency:Approx. 250KHz Input coupling:AC, GND, DC Maximum input voltage:400V (DC+AC peak), AC: frequency 1KHz or lower. When set probe switch at 1:1, the maximum effective readout is 40V pp Or set prove switch at 10:1, the maximum effective readout is 400 V pp Common mode rejection ratio: 50:1 better at 50KHz sinusoidal wave. Isolation between channels: (At 5m V/DIV range) >1000:1 at 50 KHz >30:1 at 15 KHz >30:1 at 35 KHz CH2 INV BAL:Balanced point variation: ¡Ü1 DIV (Reference at center graticule) Triggering Source CH1, CH2, LINE, EXT(CH1and CH2 can be selected only when the vertical mode is DUAL or ADD). In ALT mode, if the TRIG.ALT switch is pushed in, it can be used for alternate triggering of two different sources. Coupling:AC: 20Hz to full bandwidth Slope:+/- Sensitivity:20Hz~2MHz: 0.5DIV, TRIG-ALT:2 DIV,EXT:200mV 2-20MHz:1.5DIV TRIG-ALT:3 DIV, EXT:800mV TV:Sync Pulse more than1 DIV(EXT:1V) Triggering Modes AUTO: Sweeps run in the free mode when no triggering input signal is applied. TV-V: This setting is used when observing the entire vertical picture of television signal. TV-H: This setting id used when observing the entire horizontal picture of television signal. EXT triggering signal input Input impedance Max. Input Voltage Approx: 1M ohm//Approx. 25 pF 400V AC: Frequency not higher than 1KHz.
