AVT548 A

Low-voltage digital circuits (LV) become everyday in microprocessor and digital technology. Their use requires appropriate tools to test proper operation. Kit AVT548 is a specialized probe of logic states. Its adjustment (determination of logic levels) to the system under test consists in touching the tip to the supply voltage and pressing the button. This method of operation allows you to use the device in systems where there are several zones of supply voltages. The information is read by four LED diodes - their indications indicate high and low status, rectangular waveform as well as positive and negative pins. Invalid states are also signaled.

The device is especially recommended on the website and all electronics technicians involved in digital technology

Selected sampler parameters:

• operating modes: CMOS LV, TTL
• minimum pulse width - <10 ns
• maximum frequency of a square wave (50% fill) - approx. 100 MHz
• indications - LED diodes and LCD display
• built-in constant voltage voltmeter (0-5 V, resolution 0.1 V)
• power supply - 5 V (TTL), 1.6-4.4 V (CMOS LV)
• in the set there is a printed circuit board (without a pre-programmed circuit) and documentation
