Generally speaking, the slower the slew rate (rise time) being measured, the greater the influence from the noise floor. The jitter measurement floor specification takes into account the oscilloscope’s noise floor.

WebOct 23, 2007 · Slew rate becomes a problem if you try to drive the grid (s) of the final with something like a 12AX7 drawing plate currents on the order of a milliamp. It isn't going to be able to source the required current. Yet you see that all too often. I include grid drivers in my designs for just this reason. WebOct 31, 2008 · Rise and fall times are just that, time measurements specified by a single unit. Slew rate is a units per time (eg. volts per time) measurement, specified with two units; eg. volts / time. Slew rate is typically used to describe an amplifier (look at a spec sheet for an op amp). Rise and fall times are typically used describe signals. rhys fawr ap maredudd

WebNov 19, 2024 · The slew rate will help define the maximum scan speed of the system. Maximum gradient strength is measured in units of millitesla per meter (mT/m), rise time … WebApr 26, 2024 · In terms of current slew rate, fast enough also depends on the size of the load step. For example, consider a load step of 2 A with a slew rate of 2 A/usec. Total transition time is 1 usec, which we will equate to rise time (10% to 90%). Rise time is approximately 2.2 times the circuit time constant τ, which equals 1/ (2*π*f). WebSep 13, 2024 · Slew rate is a critical factor in ensuring that an OP amp can deliver an output that is reliable to the input. Slew rate changes with the change in voltage gain. Therefore, it is generally specified at unity (+1) … rhys fenlon
