I need to measure slew rate of differential signal transition from 15mV to 30mV(which is having a slew rate approximately 1.5V/uSec) across 50 Ohm Resistor .For measuring slew rate i am having an instrument which can measure the slew rate
of signal.But it can work with minimum 150mV threshold voltage with input impedance 100 Ohm.
So, I am planing to amplify the signal 10 times(with gain=10) using either differential input differential output or differential input to single ended output amplifier. Initially i have selected AD8129. But it require measuring instrument should have high input impedance.So i should not use it.
Now i am planning AD8132. But I am not sure weather it will work with gain 10.
Can anyone suggest the amplifier which suites better for amplifying 15mV-30mV signal with gain 10 and then measuring slew rate of amplified signal using 100 Oham input impedance measuring device.
