Oscilloscope Preamp
In many oscilloscopes, the most sensitive range is between 2 to 5 mV, although it is often possible to improve this to 1 to 2 mV by using a variable gain control. To achieve even better sensitivity, the current preamplifier,...
Fast data aquisition 1
This diagram illustrates a high-speed data acquisition system featuring eight differential inputs and a 12-bit resolution utilizing the AM-543. When the control logic is synchronized such that the Sample-Hold-ADC section converts one analog value while the mux-amplifier section stabilizes for...
Precision-threshold-detector
This circuit requires low noise, stable offset voltages, high open-loop gain, and high speed. These requirements are fulfilled by the HA5147. Standard variations of this circuit can be easily implemented using the HA-5147. For instance, hysteresis can be introduced by...
Simple Circuit to Turn your Oscilloscope into a TDR
This simple circuit allows the use of an oscilloscope as a Time Domain Reflectometer (TDR). The operation involves sending a pulse down a cable and observing the resulting reflections.
The circuit design for utilizing an oscilloscope as a Time Domain Reflectometer...
The MAX1407 Complete Data Acquisition System Simplifies Your System Designs
A design example for a portable data acquisition system is provided, which significantly simplifies the circuit design task.
The portable data acquisition system is designed to capture, process, and store data from various sensors and input devices. This system typically includes...
Four-Channel Oscilloscope Adaptor
This circuit allows the simultaneous display of four signals using a single channel of an oscilloscope. It effectively switches each of the inputs to the oscilloscope.
The circuit utilizes a multiplexer to manage the input signals. A typical configuration would involve...
high side current measurements
It is often challenging to measure the current in the positive lead of a power supply, such as a battery charger. Fortunately, specialized integrated circuits (ICs) have been developed for this purpose in recent years, including the Burr-Brown INA138 and...
USB Live Oscilloscope: ADCV Board
The analog input is initially connected to a fast non-inverting buffer amplifier (OPA353) configured for unity gain, which safeguards the analog-to-digital converter from out-of-range voltages. The ADS830 is an economical 8-bit analog-to-digital converter that accommodates sampling clocks ranging from 10...
USB Live Oscilloscope: Main Board
The two input boards (ADCV or digital) are connected to AD_CTL1, AD_DATA1, AD_SUP5V_1, and AD_SUP3V3_1 for the first board, with the second board using the same connections but with a suffix of 2. To transfer sampling data, the 16 digital...
