Using the inverting circuit below.

        Use these values:

R₁ = 5000W.
R₀ = 5000W.
 
• Use a square wave input that just drives the output close to saturation.  If you're using +12 and -12 volt supplies, drive the output to +10v and -10v.
• Determine the fastest rate at which the output can change.  That rate is the slew rate limit.
