Feature

●Designed for level testing and design of an integrated circuit chip, contains the root of a dynamic index compression circuit (example: input 1V, the 1V, input 4V, the 2V, input 9V, the 3V).
●Taking into account the dynamics and the instruction pointer swings moderately, which prevents the small signal pointer from moving, the large signal pointer supports the state.
●No standalone power supply required, power supply leads directly from the original.
●Reduce the cost of a transformer compared to TA7318P / TA7332P, while the housing inside takes up less space, the installation is more convenient and flexible.
●Enter the installation of a low-pass filter circuit to filter out high frequency interference, power supply for harsh environments (e.g. car system). Adjustable output sensitivity for a variety of specifications.


Description

Function:
1. Designed for level testing and the design of an integrated circuit chip, contains the root of a dynamic index compression circuit (example: input 1V, the 1V; input 4V, the 2V; input 9V, the 3V).
2. Taking into account the dynamic and instruction display affordability moderate to avoid the small signal pointer not moving, the large signal pointer supports the condition.
3. No need for own power supply, power supply goes directly from the original.
4. Compared to TA7318P / TA7332P, reduce the cost of a transformer, while the chassis inside takes up less space and the installation is more convenient and flexible.
5. Enter the installation of a low-pass filter circuit to filter out high-frequency interference, power supply for harsh environments (e.g. car system). Adjustable output sensitivity for a variety of specifications.
