Types of optical oscilloscopes and how to choose them

　　According to the different power supply modes, optical oscilloscopes are divided into AC powered oscilloscopes, DC powered oscilloscopes and AC/DC dual-purpose optical oscilloscopes. AC powered oscilloscopes, such as the domestic SC-16, SC 18 and SC-60 models, are generally used in laboratories or work sites with AC power; DC powered oscilloscopes, such as the domestic SC-9, SC-17, SC-19 and SC-22 models, are small in size and weight, and are suitable for occasions without AC power; AC/DC dual-purpose optical oscilloscopes, such as the domestic SC-10, SC-11 models, have the characteristics of the above two types of oscilloscopes, and can record directly with ultraviolet light, and can also record darkly with an incandescent lamp source.

　　According to the different recording methods, it can be divided into two forms: direct recording and dark recording. Direct recording can display images under ordinary light, so the recorded image can be seen directly; dark recording only requires ordinary light sources, but needs to be developed and fixed in a dark room, so the recorded image cannot be seen directly during the test. This type of optical oscilloscope mainly includes models such as SC-17, SC-19 and SC-22.

　　According to the difference of magnetic system, it can be divided into single magnetic type and common magnetic type. Each vibrator of single magnetic type oscilloscope has a magnet, such as SC-1 optical oscilloscope; all vibrators of common magnetic type oscilloscope share a magnet, and the vibrators are inserted into each hole of the magnet. At present, most oscilloscopes use common magnetic type. You can choose reasonably according to the test requirements and conditions.
