This application note will introduce the basic concepts of power measurements and clarify the definitions of key terms such as: Root mean square, Real power, Apparent power, Power factor, Crest factor, Harmonic Distortion and more.
Eliminating sensor errors in loop calibrations
Significant performance improvement can realized by optimizing the loop calibration measurement system to better accommodate the unique characteristics of the temperature sensing element. All temperature probes and their sensing elements are unique, with variations in materials, construction and usage, or exposure to different environments. This uniqueness continues throughout the useful life of the sensor, in the form of drift due to mechanical shock and vibration or to contamination of the materials when exposed to the material they are measuring. Only through periodic verification can these differences and changes be accommodated, improving total measurement performance.
TDR Impedance Measurements: A Foundation for Signal Integrity
At today's high operating frequencies, anything that affects your signal's rise time, pulse width, timing, jitter or noise content can impact reliability at the system level. Mismatches and variations can cause reflections that decrease your signal quality as a whole. To ensure signal integrity, it is necessary you understand and control impedance in the transmission environment through which the signals travel.
Power MOSFET Capacitance (Ciss, Coss, Crss) measurement with up to 3kV bias
Ciss, Coss and Crss of MOSFET are measured by sweeping voltage to 2kV. B1505A enables up to 3kV biased capacitance measurement.
Basics of Op Amp Gain Bandwidth Product and Slew Rate Limit
Op amp gain-BW product and slew rate limiting are defined, discussed and demonstrated on the bench. This discussion applies to the majority of general purpose op amps on the market - as most op amps are internally compensated with a single dominant pole.
Boundary Scan Basic Tutorial
