A power meter and light source or an optical loss test set ( OLTS ) is used to test end-to-end loss, and an optical time-domain reflectometer may be used to identify significant point losses or return losses.

Reflected color can be measured using a " spectrophotometer " ( also called " spectroreflectometer " or " reflectometer " ), which takes measurements in the visible region ( and a little beyond ) of a given color sample.
33.
A "'time-domain reflectometer "'( "'TDR "') is an electronic instrument that uses time-domain reflectometry to characterize and locate faults in metallic cables ( for example, twisted pair wire or coaxial cable ).
34.
In a radio frequency ( RF ) transmitter, VFOs are often used to tune the frequency of the output signal, often indirectly through a heterodyning process similar to that described above . timing signal generation for oscilloscopes and time domain reflectometers, and variable frequency audio generators used in musical instruments and audio test equipment.
35.
It is also home to the National Deuteration Facility, which runs a user service providing both bio-synthesis and bottom-up organic synthesis of molecules for use in neutron scattering, triple-labelled NMR, and other studies, and operates two small-angle X-ray scattering instruments and an X-ray reflectometer.
36.
The tight time-matching and stability, low power dissipation, high and constant input impedance, and small size and low cost of the sampling heads and pulsers of the RACE will help facilitate a new generation of low cost radar communications transmitters and receivers, time domain reflectometers and transmission test sets, and time domain imaging systems.
37.
Because of their high pulse surge capabilities, PP capacitors are suitable for use in applications where high-current pulses are needed, such as in time-domain reflectometer ( TDR ) cable fault locators, in welding machines, defibrillators, in high-power pulsed lasers, or to generate high-energy light or X-ray flashes.
