The '''Tektronix Type 130''' is a self-contained instrument that measures inductance and capacitance.
|manufacturer=Tektronix
The 130 makes an LC oscillator using the device under test
|model=130
and a capacitor or inductor internal to the 130. That oscillator's frequency is
|class=Multimeter
measured by mixing it down using a fixed reference frequency, generating a pulse at each zero-crossing, and
|series=
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 '''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.
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".
Early units (SN 101-5000) have a narrow boxy case that slides off the chassis, 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".
At some point between SN 101 and SN 842, the case color changed from brown to blue.
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.
