DC servos can also turn into LF oscillators if the input capacitor to the amplifier at the LTP is an electrolytic. If this part dries out a bit the time constants in the circuit change and the thing can easily go from damped, to underdamped, to LF generator. Not nice! I don't browse...
What is Pullability? The pullability is the frequency range over which the VCXO can be pulled for a given change in control voltage. It is specified in terms of parts per million (ppm) for a given voltage. As is expected, large pullability figures give a larger tuning range, but VCXOs...
Learn what is a signal amplifier, how does it work, its applications, benefits, and how they are used in the context of a data acquisition (DAQ) system.
A crystal unit is an electronic component that uses the piezoelectric effect of a quartz crystal to generate accurate signals and stable frequencies for operating electronic devices. Since a quartz crystal unit by itself cannot output clock signals, it is always used in combination with an oscillatio...

Q1. At what voltages should you consider using a Big Switch PCB? Generally once the voltages exceed 200V it is recommended to use a custom Big Switch PCB over a standard PCB for better safety and reliability. The exact threshold depends on current levels too – for example, 100V could sti...
Output on 0A (Zero Drift): ≤0.01A; Temperature Drift: 200ppm/ºC; Power Supply: 12V or 24V DC(Default 24VDC); Operating Temperature: -20ºC to 70ºC; Type: Integrator/Amplifier/Converter/Signal Conditioner; Output Signal Type: Analog Output;...
a relativistic correction factor is applied to adjust the relevant quantities (i.e., perveance, Brillouin field, DC beam velocity, coupling coefficient, beam loading conductance, plasma frequency and plasma propagation factor). The relativistic correction factor (σ) includes the ratio of the velocity...
