About This Instrument
The Vartech SS-5030BC is a 30 MHz dual-channel analog oscilloscope with a built-in component tester (C.T.) — the SS-5030B platform with an additional component tester that displays the I-V characteristic of passive and active components directly on the CRT screen. Resistors, capacitors, inductors, transistors and diodes can be checked in-circuit without powering the circuit. All oscilloscope specifications are identical to the SS-5030B.
Key Features
- 30 MHz dual-channel oscilloscope — identical spec to SS-5030B
- Built-in component tester — I-V characteristic display on CRT for R, L, C, transistors and diodes
- In-circuit component checking without powering the circuit — safe fault finding
- ×10 sweep magnification, ALT triggering, AUTO/NORM/TV trigger modes
- 5 mV to 5 V/div sensitivity, full trigger source selection
