Keysight (Agilent) 44473A 4x4 Matrix Switch Module

The Agilent 44473A Matrix Switch provides a 4 x 4 matrix of 2-wire switches. Each node (crosspoint) in the matrix contains a latching relay that connects a row to a column. Both Hi (H) and Lo (L) lines are switched. More than one switch can be closed at a time, allowing any combination of rows and columns to be connected. This matrix switch offers highly flexible switching for testing devices over a frequency range of dc to 100 kHz. Multiple 44473A modules may be connected together to form a larger matrices. The 44473A can also be used in conjunction with other modules (such as the 44470A 10-Channel MUX) to provide a wide variety of switching combinations. When wiring between multiple modules, keep wire length as short as possible to minimize noise and signal degradation.

dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
