10. Reections from excessive penetration of detector probe may alter
position of standing wave or even result in uneven spacing between
nulls.
11. Presence of higher-order modes of propagation in the vicinity
of waveguide discontinuities may also result in uneven spacing
between nulls.
12. Excessive attenuation introduced may necessitate excessive probe
penetration for adequate output, which may alter positioning of
standing waves.
10.7 Some Standard Norms
The block diagrams for experimental setups involve several devices and
components and some of these bear more than one name, a brief ...
