As a simple measurement example, consider an amplifier to be pulsed with a PRF of 30 kHz and a duty cycle of 3%. The measurements will be made with an IFBW of 1 kHz and compared to non-pulsed measurements at a pair of power levels.

By inspection, it is clear that if H Loop (s) = –1, the transfer function of the system, H Loop (s) will become infinite – and that would be an unstable system.

The measurement result is a mathematical representation of the pulse power rather than an actual measurement and assumes constant peak power.
The pulse power averages out any aberrations in the pulse, such as overshoot or ringing. For this reason it is called pulse power and not peak power or peak pulse g: CO book.
measurements allow scientists and engineers to capture ultra-high-speed current or voltage waveforms in the time domain in order to study dynamic properties. This pulsed I-V testing applications e-guide features a concentration of application notes on pulsed I-V testing methods and techniques using Keithley’s Model SCS Parameter g: CO book.
Loss of power The power of a pulsed signal decreases as function of the duty cycle of the pulse. The exact power loss is given by the formula 20 log x duty cycle. For example, for 10 % duty cycle the power of the modulated signal is 20 dB lower than in CW, and File Size: KB.

This is known as a gain transfer technique. At lower frequencies, it is convenient to use a 1/2-wave dipole as the standard. At higher frequencies, it is common to use a calibrated gain horn as a gain standard with gain typically expressed in g: CO book.

PULSED MEASUREMENTS Pulsed IV Measurement Basics There are two major types of pro-cesses causing inaccuracy of static DC IV results. Self-heating of the device causes inaccuracy of typical DC IV measurements.

This note reviews the popular techniques and instruments used for measuringMissing: CO book. The result is a pulse with a very sharp raising time and a slower falling time, with a typical duration of 1 to ns. The pulse duration depends on several parameters: the type of gain medium and how much energy it can store, the cavity length, the repetition rate of the pulses and the pump energy, to mention the most important ones.
In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal.
It is usually defined as the mean ratio of the signal amplitude Missing: CO book. Positron annihilation lifetime spectroscopy (PALS) is a non-destructive spectroscopy technique that allows studying a variety of phenomena and material properties on an atomic scale.
