Some commercial microwave noise generators use avalanche diodes to create a large excess noise figure that can be turned off and on. The impedance of the diode is different during the two states, so an output attenuator is used. The attenuator reduces the noise source output, but it minimizes mismatch loss. (Swain & Cox 1983, p. 26).
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 ...
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 ...
In the real world some low-end devices may only support a subset of these 488.2 commands, or may even accept the commands but not perform any operation. A user should check the official programmers manual for each device before assuming all of these 488.2 commands are supported.
