The Digital Stroboscope Type 4913 can be used with the 1053 to provide slow motion or
frozen visual analysis of the structure under test (chapter 1, Fig. 1 0). The stroboscope
flash frequency is synchronized to the 1053 generator frequency. Consequently, an auto-
matic frequency sweep can be used for visual resonance detection and a manual fre-
quency sweep for detailed visual analysis at a resonance.
