This device is a power supply that provides the necessary power from a mobile battery to our preamp IMP series and filter IMF series. The input is a USB Type-C connector, and the output is an HR10A connector. By using this device, you can use the IMP/IMF series in environments without commercial AC power. It is compact, lightweight, and highly portable. We offer custom contract development for low-noise circuits, analog circuits, filter circuits, signal processing circuits, and circuit design.

This is a product from our Low Noise Amplifier series. With an input equivalent noise voltage of 5nV/(Hz^0.5) (@1kHz) and low noise characteristics, it is useful for amplifying and analyzing small signals. The gain can be selected via DIP switches at 0/10/20/30/40/50/60dB. We offer the IMP240 with differential (balanced) input and the IMP241 with unbalanced input. The IMP240 is compatible with HR10A metal connectors suitable for twisted pair shielded cables, which helps reduce the influence of common mode noise. The IMP241 features an easy-to-use BNC connector. It comes standard with a high-pass filter (HPF) at 100Hz and a low-pass filter (LPF) at 100kHz, allowing for the suppression of unwanted low-frequency and high-frequency noise. If you wish to change the cutoff frequencies of the HPF/LPF, please contact us. It is compact, lightweight, and highly portable. We also offer custom contract development for low noise circuits, analog circuits, filter circuits, signal processing circuits, and circuit design.

This is a product from our Acoustic Emission (AE) series. It helps amplify weak AE signals due to its low noise. It is generally easy to use, with a gain of 40dB and a high-pass filter at 50kHz. There are models compatible with a 5V line drive power supply (IMA242-05) and a 15V power supply (IMA242-15), which can be connected to various devices. It is compact and lightweight, making it highly portable. We also offer custom development services for acoustic emission-related equipment. Please feel free to contact us for new AE development or AE equipment manufacturing. *You can view the instruction manual and company information by downloading the PDF below.*

This is a product from our Low Noise Amplifier series. With an input equivalent noise voltage of 2.5nV/(Hz^0.5) (@1kHz) and low noise characteristics, it is useful for amplifying and analyzing small signals. The gain is 40dB and it has a wide bandwidth. We offer the IMP242 with differential (balanced) input and the IMP243 with unbalanced input. The IMP242 features an HR10A metal connector suitable for twisted pair shielded cables, which helps reduce the influence of common mode noise. The IMP243 has an easy-to-use BNC connector. It is compact and lightweight, offering excellent portability (smaller than our IMP240/241). We also provide custom contract development for low noise circuits, analog circuits, filter circuits, signal processing circuits, and circuit design.

To detect weak signals, amplification is necessary, but for the signal not to be buried in noise, low noise in amplifiers is crucial. Since the amount of noise is proportional to the square root of the bandwidth, limiting the frequency bandwidth contributes to reducing noise. This product is portable, compact, lightweight, and excels in portability. While reducing noise solves many problems, appropriate processing for the desired challenges is necessary. Our company develops and manufactures products that approach noise reduction. We achieve better results through customization tailored to our customers' challenges. There are various methods for noise reduction, but here we introduce the IMP series low-noise preamplifiers, IMF series frequency bandwidth limiting filters, and IMG series mobile low-noise power supplies/adapters as approaches based on the fundamentals of low-noise amplification and frequency bandwidth limiting filters. We offer high performance that is easy for anyone to use, simple, eliminating unnecessary features and focusing on what is needed, with the capability to accommodate custom specifications for our customers. Proper analog signal processing reduces the processing burden on digital and software, enhancing overall performance. We are engaged in the development and design of electronic devices and measuring instruments that apply analog/digital signal processing. For more details, please refer to our catalog and website.
