The device is good for beginner radio lovers, because you can buy two devices in one for a small price: a tester of a wide range of radio parts, and a small oscilloscope with a pleasant interface and a color display. The device can become the first oscilloscope of a radio amateur, or a useful addition in the laboratory of an experienced electronics engineer, which allows you to check and repair mobile equipment, on the road, in the field, or simply without being tied to a laboratory table.
Main functions:
1. Digital oscilloscope:
Passbands = 200 kHz
Mixing frequency = 2.5 MS/sec
Input resistance = 1 MΩ
The range of input stresses with a divider of 1:1 = 80Vp ($i40V)
The range of input stresses with a divider of 1:10 = 800Vp ($400V)
Sensitivity vertically = 10mV/Div — 10V/Div
Horizontal sweep = 10us/Div — 500s/Div
Sync Modes = Auto/Normal/Single
Timing Type = Signal Edge, Signal Fall
Synchronization level — Custom, with indica
Oscillogram freezing — HOLD function
Automatic Measurements – Maximum, Minimum, Average, RMS, Peak-to-Peak, Frequency Meter, Period Length, Courtesy.
2. Generator of test Shemi signal:
Generator Shim signal in oscilloscope mode – frequency from 0 to 80 kHz, respectability 0…100%, amplitude 5V.
Test signal generator in component tester mode – from 1.5 kHz to 10 MHz
3. TESTER of electronic components:
