Agilent / HP / Keysight 353A
353A PATCH PANEL
This Patch Panel contains a precision 110dB attenuator and two sets of impedance matching transformers.
One set of transformers matches 900, 600 or 135ohms lines.
The other set of transformers terminates the line in 900, 600, or 135ohms or in 10kilohms for bridging measurements.
This unit 's used in conjunction with an oscillator and a voltmeter.
This combination of instruments is intended for measurements of transmission and system characteristics such as attenuation, frequency response, and gain.
