The new 1 GS/s 14 bit quad differential channel High Resolution Oscilloscope.

This powerful USB 3.0 super speed oscilloscope combines fast sampling up to 1 GS/s with high resolutions of 12, 14 and 16 bit and a large memory of 64 MSamples on all four channels. The oscilloscope supports continuous streaming measurements up to 200 MS/s and can be synchronized with other oscilloscopes using the CMI interface to form a multi channel combined instrument with synchronized time base. The CMI interface is available by default on the Handyscope HS6 DIFF. Optionally, the Handyscope HS6 DIFF can be delivered with SureConnect connection test and resistance measurement on each channel. Also, the Handyscope HS6 DIFF can be delivered with SafeGround option. With SafeGround you can switch the differential inputs of the Handyscope HS6 DIFF into single ended inputs with ground protection. It allows to make measurements using standard attenuating probes and protects the scope when a short circuit to ground is created.

4-ch amplifier BOTEG ForesTek 40 db, which is necessary for measurement by nonlinear ultrasonic spectroscopy, but also in other applications where it fits its specific properties.

Input signal:
Maximum 0.5 V (amplitude)
frequency: 10 kHz to 1 MHz

Output signal:
Gain 40 db
Max 72 V (amplitude)

It contains 4 independent amplifier channels. The amplifier is powered by a standard 230 V 50 Hz and includes overload protection. Custom can be adjusted according to the customer and to other power systems.

Can be installed in a 19" rack, where it takes 3U.

Easy-to-use digital resistance decade with many useful features.

Digitally controlled resistance decade with continuously adjustable resistance from 10 Ω to 10 MΩ, maximum current load of 1000 mA and a maximum voltage of 125 V.

The resistance value can be easily set using the blue arrow buttons (jump between unit sequence) and the k**b (0-9 choice of the value). The resistive switching output comes up when the user presses a green button - To protect the connected device.

Resistance decade (cascade) is an indispensable tool for development, research, service, home improvement and education.

The UP28 is a special power supply, which is used to power preamplifiers BOTEG 20 db and 40 db from a computer's USB port. Electronics can increase the voltage to the required 28 V with a very stable (without interference) course. The input voltage to this source may be in the range 3-20 V. The output current is dependent on the capabilities of the input power source, which may be a computer or other source of electric voltage. The status LED indicates the presence of an output voltage of 28 V.

The source on the input side has a standard USB-B (due to the higher mechanical resistance) and on the output side pair of Jacks 5 mm.

Dimensions: 55 x 55 x 30 mm

BOTEG Ultrasonic Sensor 90 kHz

The ultrasound sensor UTS90BNC is compact, high sensitive sensor with a resonance frequency 90 kHz. The purpose of it is the usage in sensing or transduction way. A standard sensor's usage is the acoustic emission measuring (AE), the nonlinear elastic wave spectroscopy (NEWS) and the frequency analysis (RFA). In case of the interest Bohemian Technology Group s.r.o. is open to other usage too (after consultation).

The housing of the sensor is normally made from INOX – AISI 304. The custom modifications are possible. A lenght of cable and connectors are ready to be modificated too.

The sensor is designed for the usage in a very heavy environment. Because of that, the sensor is sealed precisely – the sensor is water proof (it was tested 100 mm under the water). Working temperature is from - 25 °C to + 200 °C. The sensor works both in a short term and in a long term installations too.

Preamplifier BOTEG PZ40 40 dB

The low-noise preamplifier for the acoustic emission (AE) sensors is an essential part of the larger installations, where there is a signal attenuation. The preamplifier gain is fixed to 40 dB. The power is supplied by a separated power jack 5.5 x 2.1 mm and is thus maximally prevent a distortion. The preamplifier BOTEG PZ40 is built into a compact aluminum boxe with BNC outputs type F.

Our 12-ch relay module for controlling up to 12 devices. Each relay can switch up to 240V/16A. You can set each relay to bistable or time mode. For control all functions and settings you can use RS-232 and for simple switching on/off/time you can use 12 inputs socket (to GND or to 12V). It’s great for home Automation & IoT Power Switching Engine.
