The 20 MHz Dual Trace Oscilloscope is a compact, low line and lightweight
instrument. It’s high class engineering and rugged design ensures
very reliable performance. This is a general purpose Dual Trace Oscilloscope
having both Vertical amplifiers
offering a bandwidth of DC 20 MHz and a maximum sensitivity of 2mV/cm. Stable
triggering for low level signals is obtained upto 30MHz. Full X-Y operation
is achieved by switching Channel11 into horizontal deflection system so
sensitivities for both X and Y signals. A component tester is incorporated
in the oscilloscope which gives a quick test of both active and passive
In addition Z-modulation facility is also provided. The fully stabilized internal
power supplies ensure reliable operation under adverse mains supply conditions.
The carefully selected components and Burn-in-tests ensure trouble free working
in most demanding environments. The 2530 offers five separate Add-on Modules
• Frequency Counter
• Curve Tracer
• Power Supply
• Function Generator
• Digital Voltmeter.

OSCILLOSCOPE Demonstrator Cum Trainer 3028
Oscilloscope Demonstrator Trainer is specifically designed for the study of
working of an Oscilloscope. It is a user friendly fully working oscilloscope
in an open form. The controls are placed actually at the place as they are
in the circuit schematic. Thus a trainee can locate any section, components
of the section and can study it thoroughly. the function controls and adjustment
controls are fully adjustable to the trainee to verify their effect on the
working of the scope. An illustrated Block and Circuit Schematic and the
adjustment plan right in front of trainee’s eyes helps him to co-relate
each operation during the demonstration.
