Bitscope – PC Oscilloscopes And Analyzers

BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously. Any BitScope can be used as a Digital Storage Oscilloscope, Logic State Analyzer, Spectrum Analyzer or Data Recorder. USB BitScope 310

USB BitScope 310 – PC Oscilloscope

BS310U is a robust general purpose USB Mixed Signal Scope and Data Acquisition device. BS310U is backward compatible with BS300U which it replaces.

It has 4 times as much capture buffer, a software switchable x10 and x50 analog input multiplier and AC/DC coupling, switchable 50 ohm termination, a double speed built-in USB host interface all in a physical package about 2/3 the size and weight of BS300U.

BS325 with third party software

BS325 is user programmable, software extendable and can be integrated with third party software.

To make this easy the BitScope Library is available for BS325. The library can be used to create custom applications or to integrate one or more BS325 units into specialised testing and data acquisition systems.

The library is included as standard with BS325 and is compatible for Windows, Linux and Macintosh platforms.

This Insulation Testing Reference by AEMC Instruments is a Must Read for all Instrumentation and Electrical Professionals. Even Students and Enthusiasts who want to learn more about Insulation, can find this informative. The other reference articles also are of Learning Interest. Insulation Testing is a Part of Power, Energy, Green, Solar Systems as well. It is an Important part of Product Safety.

Megohmmeters/Insulation – AMEC 6505 5000V Megohmmeters

Read -Understanding Insulation Resistance Testing

AEMC is an industry leader in current measurement probes, power quality analyzers, ground resistance testers and insulation resistance testers. It was Founded in 1893.

AEMC Instruments – 200 Foxborough Blvd., Foxborough, MA 02035 USA

Seen on the right is the Megohmmeter from AEMC. 6505 is a portable battery/mains powered instrument in a rugged field case.

This Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR) and Polarization Index (PI). The Model 6505 displays the test voltage, insulation resistance and the leakage current during the test.

delabs notes-

Even i had built and sold a few – Insulation Tester or Teraohm Meter. It could even measure Polarization Index.

Energy and Power Measurements

To make an analog design using log amps or multipliers, discovercircuits – four-quad is good for learning. Using a uP for math is better. Look at these links below. Build a Power Meter !

Temperature Calibrator Milli Volt Source

This is a Milli-Volt and Milli-Amp Source for Calibration of Temperature Measurement and Control Instruments using Thermocouples. There is also a Passive Variable Resistance Source for Simulating a PT-100 RTD Sensor. This calibrator was a simple solution i built. This instrument itself was calibrated by Instruments like the Calibrators from Omega which are the best you can get.
