A tape drive calibration meter that is adapted to display a number of calculated parameters for providing a numerical display of such conditions as skew, tape velocity, amplitude, and tape tracking. The tape drive calibration meter preferably has two inputs on two separate channels with each including an automatic gain control amplifier and a peak detector. Time interval measurement circuitry is coupled from the peak detector for carrying out measurements involving velocity and skew. After amplification, the detected signals on one of the channels are also transferred along a second path including a peak, follow and hold circuit and an analog-to-digital converter circuit with controls. Amplitude measurements and head positioning computations are taken by signals transferred along the second path to the peak, follow and hold circuitry and analog-to-digital conversion circuitry.
