INTENDED USE1.
This oscilloscope is a portable-type, dual-channel oscilloscope, its bandwidth of DC is up to 30MHz, and
its maximum sensitivity is 1mV/DIV. The time base provides a maximum sweep time of 0.2uS/DIV. The
sweep speed becomes 100nS/DIV after magnifying 10 times. The oscilloscope uses a 6-inch rectangular
type cathode-ray tube with red internal graticule. This is a sturdy, easy to operate and exhibits high
operational reliability product.
This product fulfi ls European and national requirements related to electromagnetic compatibility
(EMC). CE conformity has been verifi ed and the relevant statements and documents have been
deposited at the manufacturer.
Unauthorised conversion and/or modifi cation of the device are inadmissible because of safety and
approval reasons (CE). Any usage other than described above is not permitted and can damage the
product and lead to associated risks such as short-circuit, fi re, electric shock, etc. Please read the
operating instructions thoroughly and keep them for further reference.
FEATURE2.
High intensity CRT with high acceleration voltage:1.
The CRT is a high beam transmission and high intensity type with a high acceleration voltage of 2kV.
It displays readable traces clearly even at high sweep speeds.
Wide bandwidth and sensitivity:2.
In addition to wide bandwidth, DC-30MHz (-3dB), the instrument provides high sensitivity of 5mV/DIV
(1mV/DIV at ×5 MAG). A 30MHz frequency is obtained with improved triggering synchronization.
Alternate triggering:3.
Even with an observation of two different frequency waveforms, each waveform can be triggered
stably.
TV sync triggering:4.
The oscilloscope has a sync separator circuit for TV-V and TV-H signals triggering.
CH1 Output:5.
A signal from 50W output terminal of CH1 located on rear panel can be applied to frequency counter
or other instruments.
Z-Axis Input:6.
Intensity modulation capability permits time or frequency markers to be added. Trace blank with
positive signal, TTL compatible.
X-Y operation:7.
Set the switch to X-Y to operate the instrument as an X-Y oscilloscope. CH1 can be applied as a
horizontal defl ection (X-axis) while CH2 provides vertical defl ection (Y-axis).
