Product Description

Hurry up..Offer Limited..!!


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).

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).

CH2 INV BAL Balanced point variation: 1 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: 1.5 DIV
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.
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.
