The {{Title|General Radio 874-LBB Slotted Line}} was introduced in {{Catalog T}} and remained available through {{Catalog 1978}}. Its function is to observe the electric field along the inside of a coaxial transmission line using a carriage-mounted probe moving along the line. | |||
By observing minima and maxima of a standing-wave pattern, parameters like frequency, standing-wave ratio, or impedance can be measured, and thereby the characteristics of a circuit connected to the load side of the line can be determined. Applications include analysis of antennas, components, coaxial elements, and networks. | |||
The 874-LBB is an update of the [[874-LBA]] with improved precision, extending the frequency range to 8.5 GHz. | |||
