130: Difference between revisions

Revision as of 08:32, 22 January 2021

The Tektronix Type 130 is a self-contained instrument, designed by Cliff Moulton and introduced in 1959, that measures inductance and capacitance.

There are at least two versions of Type 130. Early units (SN 101-5000) have a narrow boxy case that slides off the chassis, brown paint, backlit meter, and are marked "TYPE 130 L,C METER". Later units (SN 5001-Up) have a wider, rounded case with side panels that pop off, blue paint, non-backlit meter, and are marked "TYPE 130 L-C METER".

Internals

The 130 contains an LC oscillator with a tank circuit formed by the device under test and a capacitor or inductor internal to the 130. The 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.
