Product Details

Specifications

*Build-in 6 Digit Frequency Counter
*20MHz/40MHz/50MHz Dual Channel
*10 times sweep magnification
*TV Synchronization,X-Y

Key Features:

High intensity CRT with high acceleration voltage
Trigger level lock function which makes the triggering adjustment unnecessary
Alternate triggering: Even an observation of two waveforms of different frequencies, the waveform of each channel is stably triggered.
TV sync triggering: The oscilloscope has a sync separator circuit for triggering of TV-V and TV-H signals.
X-Y operation: Set the switch to X-Y. Then the instrument works as an X-Y oscilloscope. CH1 can be applied as horizontal deflection (X-axis) while CH2 provide vertical deflection (Y-axis).

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
		AC coupling: Low limit frequency 10Hz. (With reference to 100KHz, 8DIV. Frequency response with-3dB.)
	Rise time	Approx. 17.5nS
	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 (14 Vrms at sine wave), Or set prove switch at 10:1, the maximum effective readout is 400 V pp (140 Vrms at sine wave).

Triggering	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: 1.5 DIV TRIG-ALT:3 DIV, EXT:800mV TV: Sync Pulse more than 1 DIV(EXT: 1V)
	Triggering Modes	AUTO: Sweeps run in the free mode when no triggering input signal is applied. (Applicable for repetitive signals of frequency 25Hz or over) NORM: When no triggering signal is applied, the trace is in the ready state and not displayed.
