This wide-band portable oscilloscope, Model VP- 5520A, which is compact and light in weight, is designed to cover use in a wide range of environmental conditi*** through full employment of transistors and ICs.
The VP-5520A has a vertical amplifier circuit which permits a dual-trace display in such a wide-band of from DC to 200 MHz.
The sensitivity range is from 2 mV/DIV to 12. 5 V/DIV. and by connecting channels 1 and 2 in cascade it can be increased to a high vertical deflection factor of 400 μV/DIV.
The trigger circuit operates stably in the entire frequency range of measurement and has an auto trigger facility. The sweep time is wide in range of from 2 nsec/DIV to 1.25 sec/DIV, and a delayed sweep feature of the trigger circuit increases measurement accuracy.
The instrument can also serve as a precise X-Y oscilloscope or triple-trace oscilloscope with the third trace to view a trigger signal in the display.
The built-in sampling circuit has a facility to permit the recording of the vertical axis signal on a recorder or the like, and the instrument finds a wide variety of application such as record and analysis of the result of measurement as well as connection with other system.
The power supplies are all regulated and hardly affected adversely by a large voltage fluctuation in the mains.
The operating temperature range is from 0° to +50°C, and the warm-up time is 10 min. or less.
