Lab 3-1. Slew Rate
Goal : To find the slew rate of the OP amplifier.
a) Set the generator to provide a 2 Vpp sine wave at 200 kHz.
Analysis : Sketch the input/output signal and calculate the slew rate.
Above picture is what I drawn for simulation through the Pspice.

Above picture is the experiment result. The upper graph is input signal measured near the voltage source. As I set, the graph showed the sine wave with 4Vp-p (the machinery problem which understand the 2Vp-p as just 2V peak voltage) and 200kHz. The lower graph is output signal measured at the output node. The output looks strange without considering slew rate.
The circuit is inverting op amp. The closed loop gain is – (10k / 10k) = -1. So the result has to be inverted and it does with some delay. I guess this delay was caused by the internal capacitors in the equipments or op amp. In practical circuit, there are some limitations of implementation; in other words,
