11. A signal generator generates a sonic pulse from the emitter which is recorded by the sensor. 12. RF signal generators are available as benchtop instruments, rackmount instruments, embeddable modules and in card-level formats. 13. Quartz crystals are also found inside test and measurement equipment, such as counters, signal generators , and oscilloscopes. 14. "' Wavetek "'was an electronic test equipment manufacturer that made function generators, signal generators and service monitors. 15. During this period Tektronix would also expand its test equipment line to logic analyzers, signal generators etc. 16. The network analyzer needs a test signal, and a signal generator or signal source will provide one. 17. A distortion of 0.0001 % can be achieved by an audio signal generator with a relatively simple circuit. 18. Even so, methinks this is less precise than methods using a signal generator .-- mattb @ 2007-03-20T21 : 50Z 19. A "'pitch generator "'is a type of signal generator optimized for use in Hz & ndash; 20 kHz ). 20. There are many different types of signal generators with different purposes and applications and at varying levels of expense.
