874-LBB
The General Radio 874-LBB Slotted Line was introduced in Catalog T (1968) 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.
