SMD IM-SG+ (Impedance Meter / Signal Generator PLUS)

SMD Precision AC Impedance Meter – Frequency range: 10hz-20khz
All New Auto-lock feature does the stopping (top or bottom) for you!
Low, Mid, High frequency range for more precision.
New, Super smooth operation of the frequency knob
Min/Max impedance hold function
Obtain a driver’s T/S Parameters*
Quickly and safely locate stock speakers (and locations) in the vehicle.
Determine speaker crossover set points
Find tuning frequency of passive radiator
Quickly determine frequency of any enclosure (sealed, ported, bandpass, etc) using Auto-lock
Quickly find the Fs of any speaker using auto-lock for proper tuning of that driver.
Find box volume, even odd shaped sealed enclosures!
Test impedance of long wire runs
Test impedance of RCA Cables (down to 10milliohms)
Find crossover frequency of passive crossover networks**
Locate annoying rattles in vehicle
Easily output any frequency to an amplifiers input, and amplify it.
Quickly and easily determine frequency changes to an enclosure after modifying the volume or adding/removing polyfill
Pink noise generator
Used in conjunction with an SMD AMM-1, quickly determine “box rise” at a specified frequency.
Improved battery life, Double that of the original IMSG!
