Description:
This product is specially designed to amplify weak signals. For weak current, the noise is small, the precision is high, and the original signal is restored well.
Oscilloscopes are sometimes unable to measure small signals, and the instrument needs to be amplified before measuring.
Application:
Electronic engineers, maintenance, R&D personnel, college students and other oscilloscope users.
It can also be used in industrial automation measurement and control, because the sensor signal is very weak and needs to be amplified before output.
Note: This product is not a high voltage probe. The high-voltage probe is for high-voltage operation. For strong electricity, it is generally used to measure high-voltage electricity, and the accuracy requirements are not high.
Features:
- Support differential input and single-ended input
- Wide input voltage range, up to +/-10V
- 1x/10x/100x optional magnification
- Up to 10M bandwidth
- Battery powered, support USB TYPEC interface charging
- Ultra low noise, high common mode rejection ratio
- long battery life
- Exquisite metal shell, strong anti-interference ability
Specification:
Single-ended input voltage: -10V to +10V
Differential Input Voltage: -10V to +10V
Single-ended input impedance: 2M
Differential input impedance: 4M
Output Voltage: -10V to +10V
Magnification: 1x/10x/100x
Bandwidth:
G=1 -- 10M
G=10 -- 10M
G=100 -- 2M
Common mode rejection ratio: >80DB
Noise : 5nV/u221a @1KHz
Power supply: built-in rechargeable lithium battery
Good low signal amplifier for the oscilloscope probes; not cheap but well constructed. Bandwidth is only 10 Mhz but anyway useful in many scenarios. It came partially charged, so I had to charge it before use. It makes a little noise when in operation (probably a switchong converter inside for dual voltage or so). I will perform some tests with it when possible (linearity, rise time, noise level,...). Very well packaged and presented; BNC connection cable imcluded.
