130
The Tektronix Type 130 is a self-contained instrument that measures inductance and capacitance. The 130 makes an LC oscillator using the device under test and a capacitor or inductor internal to the 130. That oscillator's frequency is measured by mixing it down using a fixed reference frequency, generating a pulse at each zero-crossing, and integrating (low-pass filtering) the pulse train. This produces a voltage that is proportional to the frequency difference between the LC oscillator and the reference oscillator. This voltage is displayed on a d'Arsonval (moving coil) meter on the front panel of the 130.
The Type 130 was designed by Cliff Moulton.
