HF2 Series Pre-Amplifiers
There is a considerable advantage in accuracy for many measurement setups when the experiment stands independently of the measurement instrument. With the use of suitable pre-amplifiers, inconvenient electrical lines from the setup to the instrument are avoided, interference on the analogue signals is minimized, and impedance matching is enabled. Warsash Scientific offer a line of active probes with configurable input impedance, a wide operational range, and seamless integration with the measurement instrument software.
Key Features
- Experiments can be carried out with very short cables
- Reduction of interference
- Avoid the need for high input impedance (>1 MΩ) at the measurement instrument
- Increase in regulation loop speed and stability
- Single cable between the measurement instrument and the pre-amplifier providing power and control
- Seamless integration of pre-amplifier into measurement instrument within the graphical user interface
