Sencore -- TC154
Valve characteristic meter

The new Sencore Mighty Mite VI represents a unique breakthrough in tube testers. The Mighty Mite VI is completely solid state using the FET in a balanced bridge for an instant on checker. This new outstanding feature means that no time is wasted waiting for the checker to warm up and stabilize before accurate testing can begin. The new Mighty Mite is ready as soon as it is turned on. A full load cathode current check, high sensitivity grid leakage check, and the famous Sencore Stethos ...

Knight-Kit -- LOW CAPACITY PROBE 38K153
Probe

The input system of an oscilloscope contains a certain amount of resistance shunted by capacitance. This is called the input impedance of the oscilloscope. To the input impedance of the oscilloscope is also added the capacity of the test leads. This total shunting capacitance and resistance, when connected across a high impedance, high frequency, or broad band width circuit, may be sufficient to detune the resonant circuit or to load the test circuit and seriously distort the waveforms u ...

Sencore -- SC61
Analyzer

Introduction The SC61 Waveform Analyzer represents the first improvement in waveform measuring techniques since the first oscilloscope was introduced over 50 years ago. Before the SC61, all oscilloscopes were strictly analog devices. Even.- measurement of peak-to-peak amplitude, time, or frequency required matching the waveform to CRT graticule markings, estimating parts of a CRT division or part of a cycle of the waveform and multiplying the size of the waveform times the setting of the hori ...
