These are Instruments that Jack built. Here read Jack as me, delabs. Some were hand made, some in the form of workflow of a small firm with professional equipment. Some made in quantities, other a couple or more for R&D. The photographs of many were not taken, some products were lucky. Later i realized an album comes in handy for marketing. These days, the unimaginable has happened, you can have Albums Online, just give a URL to the prospective customer. If you are smarter, setting up an osCommerce will shake your competition to wide awake condition. Test & Measurement Instruments [Read More ....]

Oscilloscope Functions and Fourier Series. Periodic Waveforms. Watch Sine, Square, Triangle and Sawtooth Waves and Study Controls. This Scope is a Real Time Graph of Volts Y and Time X at any node of a circuit. It can show both AC and DC. Load an equation of your own and see it as a waveform on this web scope. Paste a Formula in the Equation text box, load it, it will be rendered as waveform on scope. Learn from this page ….

The Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. Soundcard Oscilloscope by Christian Zeitnitz The oscilloscope contains in addition a signal generator for 2 channels for Sine, Square, Triangular and Sawtooth wave forms in the frequency range from 0 to 20kHz. These signals are available at the speaker output of the sound card. These can be fed back to the oscillocope in order [Read More ....]
“ADI microcontroller and integrated amplifier technologies support ultra low power, small size, and AAMI-EC13 performance level requirements for portable ECG designs.” AD8235: 40µA Micropower Instrumentation Amplifier in WLCSP Package The AD8235 is the industry’s smallest, lowest power instrumentation amplifier. It has rail to rail inputs and outputs and can operate on voltages as low as 1.8V. 128 Channel, 24-bit Current-to-Digital ADC for High Slice Count CT Scanners The ADAS1128 lowers CT system cost and enables enhanced imaging using the industry’s highest level of channel integration and speed.

Instrumentation and Measurement Circuits T&M and Process Control Instrumentation have many things in common; but the conditions in which a Industrial Instrument works, may be very unfriendly. Industrial Instruments are used both in Clean-Cool Control Rooms and also in a corrosive, humid, hot and vibrating industrial environment. Even high levels of Static, Magnetic influences in conjunction with spikes and brown outs can be expected. Test and Measurement instruments are of two types, by way of its usage; Portable and Benchtop. Portable Instruments will consume low power, insulated and rugged. The Product Safety features are more stringent as they are HandHeld [Read More ....]

Here is a Millivolt Source i built for Calibration in the early days. It uses only CMOS Digital and Mixed Chips from Intersil and CD40xx Series. Later i tried a unit with 8748 part of the code in my uC section. This is with Ramp-up and Ramp-down using only two buttons. This works even now, The support below is an HRC Fuse Holder made of Phenolic or Epoxy Resin. The mV Terminations are on Top.

The usefulness of an oscilloscope is not limited to the world of electronics. With the proper transducer, an oscilloscope can measure all kinds of phenomena.XYZs of Oscilloscopes – Tektronix A Tektronix model 475A portable analogue oscilloscope, a very typical instrument of the late 1970s. This dual-trace, dual-sweep instrument had a horizontal bandwidth of 250 MHz, a maximum vertical sensitivity of 5 mV per division, and maximum (unmagnified) horizontal sweep speed of 10 ns per division. – Oscilloscope – Wikipedia Read More about Oscilloscope What is an oscilloscope Digitizers/Oscilloscopes – NI Zelscope Sound card oscilloscope BK Precision site Application Notes.
