C1-137/1

The range of service oscilloscope C1-137 is designed for specialists for repair and maintenance of electronic equipment, automation devices, communication tools, as well as for amateurs.  The availability of a TV signal sync mode (separated by rows and field) provides a stable display of the form of video signals from your TV or VCR.

Model C1-137/1 can be used as a base in order to create a small measuring laboratory for a specialist in the field of radio science.

Range Overview

That combined instrument unites a double-channel oscilloscope and 3,5 bit digital multimeter with data indication on the LCD-indicator, which provides independent simultaneous measurements.
