Technical Specifications:

Vertical System

Sensitivity : 5mV ~ 5V/DIV, 1-2-5 sequence of 10 steps

Accuracy : ≤ 3%

Fine-tuning sensitivity: 1/2.5 or less panel indicates the scale

Bandwidth : DC ~ 20MHz AC coupling : less than 10Hz ( for 100KHz8DIV Frequency Response -3dB)

Rise time : about 17.5nS

Input impedance : Approx 1MΩ/25pF

Fang Potter : the pediment : ≤ 5% ( in 10mV/DIV range ) ; other distortions : On the plus ≤ 5%

DC balance moves : 5mV ~ 5V, DIV: ± 0.5DIV

Linear: when the waveform in the grid center vertical movement (2DIV) amplitude variation ≤ ± 0.1DIV

Vertical modes : CH1 channel 1; CH2 channel 2; DUAL: Channel 1 and Channel 2 also shows that any scanning speed selectable alternate or intermittent manner ; ADD: Channel 1 and Channel 2 do algebraic sum

Intermittent repetition frequency : about 25KHz

Input coupling : AC, GND, DC

Maximum input voltage: 300V peak (AC frequency ≤ 1KHz)

Insulation between the two channels :> 1000:150 KHz ( in 5mV/DIV range )> 30:120 MHz> 30:140 MHz

Common-mode rejection ratio : at 50KHz sine wave > 50:1 ( CH1 and CH2 sensitivity setting in the same situation )

CH1 signal output: Minimum 20mV/DIV (50Ω output bandwidth of 50Hz ~ 5MHz)

CH2 INV BAL: Balance the rate of change point ≤ 1DIV ( corresponding to the center of the scale )

Trigger

Trigger source : CH1, CH2, LINE, EXT ( in DUAL or ADD mode , CH1 CH2 can choose only one , in the ALT mode, if TRIG ALT switch is pressed , can be used as alternate trigger two different signals )

Coupling : AC: 20Hz to the entire band

Polarity: + / -

Sensitivity : 20Hz ~ 2MHz: 1.0DIV; TRIG-ALT: 2DIV; EXT: 200mV; 2MHz ~ 20MHz: 1.5DIV; TRIG-ALT: 3DIV; EXT800mV; TV sync pulses > 1DIV (EXT: 1V)

Trigger modes : AUTO automatically when there is no trigger signal input , scanning in the free mode (for repetitive signal frequencies greater than 25Hz ); NORM, when the norm when there is no trigger signal , the trail is in standby mode does not display ; television games, when you want to observe a television signal ; television line , when you want to observe the line of television signals ( same frequency only when the signal is negative pulse , before the television field and TV lines with )

External trigger mode signal : input impedance of about 1MΩ/25p

Input impedance: Maximum input voltage : 300V (DC + AC peak )

Maximum input voltage : AC frequency is not greater than 1KHz

Horizontal Systems
