Wideband Voltage Amplifier (DHPVA Series)

Wideband Voltage Amplifier (DHPVA Series)

The 100/200MHz DHPVA is a high-frequency amplifier with variable gain.

■Even when changing the gain settings, the bandwidth (100/200 MHz) remains constant, featuring excellent gain flatness, low noise, and low offset drift, making it a very high-performance amplifier. ■Since the bandwidth remains constant even with different gain settings, the rise time of pulses hardly changes (within ±10%). ■Ideal for accurate and reliable time-resolved measurements. ■Utilizes a multi-stage design, allowing for the avoidance of multiple amplifiers that could lead to dynamic limitations.

High-Speed Gain Fixed Current Amplifier (HCA Series)

High-Speed Gain Fixed Current Amplifier (HCA Series)

It maintains a constant bandwidth and gain up to the specified maximum capacitance value without being affected by capacitance, frequency correction, or special connections.

In many cases where high-frequency products are used, issues such as unwanted vibrations, imperfections in ground shielding, nonlinearity, gain peaking, and bandwidth reduction due to insufficient amplifier design can arise. However, Femto's current amplifiers are designed to adequately address these problems. They prevent gain peaking, vibrations, and significant bandwidth reduction, unaffected by the signal's source parameters or wiring, with a capacitance of up to 2nF. When the capacitance is a few pF, the bandwidth of high-frequency current amplifiers significantly decreases; however, Femto's high-speed current amplifiers are not subject to this limitation and are unaffected by capacitance with a wide range. They come with two trim pots for precise offset and bias control, allowing for flexible use. Input offset current correction can be adjusted over a wide range, fully maintaining dynamics even from signals with large DC components. The bias output voltage can be adjusted within -12 to +12V using this bias trim pot.

Research bioamplifier

Research bioamplifier

It can be used for product development and research based on ergonomics and psychological engineering. It is available for measuring brain waves, electrocardiograms, electromyograms, and eye movements (EOG).

There are two series available: the "integrated type," which has an electrode box built into the main unit, and the "separate type," where the main unit and the electrode box are separated. The separate type is ideal for measurements in shielded rooms and various laboratories. The integrated type is available in 1ch, 3ch, and 8ch types, while the separate type offers 8ch and 32ch options. Due to its card-type amplifier unit, it is possible to reduce the number of cards implemented, keeping costs down while maintaining expandability. This is a bioamplifier specifically designed for research in industrial product development, animal experiments, and psychotechnology. Since it is intended for research, it does not target specific biological signals, offering a wide amplification range from 500 to 50,000 times (with the separate type reaching up to 100,000 times), and is equipped with multi-stage high-pass filters and time constants. It is optimal for the analysis and evaluation of biological signals in fields such as ergonomics, psychotechnology, and basic medical research.

A vacuum tube amplifier from a dedicated vacuum tube manufacturer in a space with "sound" ♪

A vacuum tube amplifier from a dedicated vacuum tube manufacturer in a space with "sound" ♪

A printed circuit board that achieves a balance between sound quality and performance! The vacuum tube amplifier 'TA-S01' made by a vacuum tube manufacturer.

The "TA-S01" is a vacuum tube amplifier designed to maintain stable quality over a long period. The heating components are placed on the back of the circuit board, while the heat-sensitive electrolytic capacitors are positioned on the front to keep them away from the heating components. The voltage amplification stage uses a two-stage amplification with an SRPP circuit to lower the output impedance. This allows for the comfortable driving of the 300B triode output tube, which is generally difficult to drive, fully utilizing its performance. 【Features】 - Uses our original vacuum tube "TA-300B" and rectifier tube "TA-274B" - Wideband design suitable for the high-resolution era (10Hz to 50kHz) - Easy to change speaker impedance - The pilot lamp blinks until the power supply is up, allowing for status confirmation - Equipped with a new function to adjust the amplifier's characteristics *For more details, please refer to the PDF document or feel free to contact us.
