2. Attenuator (electronics) - Wikipedia

   en.wikipedia.org/wiki/Attenuator_(electronics)

   An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...

3. Oscilloscope types - Wikipedia

   en.wikipedia.org/wiki/Oscilloscope_types

   Since then, the high-end lines of standalone oscilloscopes of all four major oscilloscope manufacturers (HP/Agilent/Keysight, LeCroy, Tektronix, Rohde & Schwarz) have been based on a PC platform. The other group of PC-based oscilloscopes are the external oscilloscopes, i.e. where the acquisition system is physically separate from the PC platform.

4. Keysight - Wikipedia

   Keysight Technologies, Inc. is an American company that manufactures electronics test and measurement equipment and software. The name is a blend of key and insight. [2] [4] The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced from the late 1960s to the turn of the millennium by Hewlett-Packard ...

6. T pad - Wikipedia

   en.wikipedia.org/wiki/T_pad

   A T-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A T pad can be viewed as being two L sections back-to-back as ...

7. Network analyzer (electrical) - Wikipedia

   en.wikipedia.org/wiki/Network_analyzer_(electrical)

   ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
