Based on the above, the new Fluke 190-502 has the margin it needs in its bandwidth and rise time capabilities for this application. Perhaps the biggest problems would be in finding a very low inductance current shunt for the current measurement, and making sure you have carefull...
Part Number:TPS2660 Greetings. I am inquiring to see if there is a gain bandwidth product or similar parameter for the IMON output. I would like to use the output to measure the current of a varying waveform and wold like to better understand how fast the IMON sig...
Historically,oscilloscopefrequency response tended to approximately follow the rule: Bandwidth x risetime = 0.35. This corresponds to a 1- or 2-pole filter roll-off in the frequency domain. Today, at the high end, most real-timedigital oscilloscopesmore closely follow this rule: ...
Figure 12: The rise time measured for a photodiode-based system with a 200 kΩ effective load resistance was 151.0 µs. The rising edge calculated using the RC low-pass filter model (red curve) is a good fit for the data. Table 1:The 3 dB bandwidths were estimated from the rise ...
InWhat’s that signal’s bandwidth?, we took a look at the classic relationship between rise time and bandwidth. A discussion of rise time often leads to the question: is this the same thing as slew rate? Slew Rate vs Rise Time
Δt=CΔV*I = 20 pF * 3 * 20 mA -> 3 ns (from: https://electronics.stackexchange.com/q ... s-on-esp32) I mean, your scope probe will always have some capacitance. As the rise time effectively is determined by how fast the mosfets in the GPIO can pump energy into the combine...
The reason for this is the time scale. The whole startup is happening in about 20us, and LDOs don't have a huge amount of bandwidth. So when a device like this that does not have the capability to start up directly into current limit begins starting ...
