The '''Tektronix Type 130''' is a self-contained instrument that measures inductance and capacitance.   
|manufacturer=Tektronix
When measuring inductance, the 130 makes an LC oscillator using the device (inductance) under test
|model=130
and a capacitor internal to the 130.  When measuring capacitance, the 130 makes an LC oscillator using the device
|class=Multimeter
(capacitance) under test and an inductor internal to the 130.  The frequency of the resulting LC oscillator 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

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


The Type 130 was designed by [[Cliff Moulton]].
There are at least two versions of Type 130.
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".
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.
