Logic Probe High Frequency Response DTL TTL CMOS Pulse Memory Logic Tester LP-1
The LP-1 Logic Probe is a high-frequency tester for DTL, TTL, and CMOS circuits, operating on 3–18V DC. It features LED indicators for logic levels and pulses, plus a pulse memory function. Ideal for laboratories, troubleshooting, education, and industrial electronic circuit testing.
مسبار المنطق LP-1 هو جهاز اختبار عالي التردد مخصص لدوائر DTL وTTL وCMOS، يعمل بجهد من 3 إلى 18 فولت تيار مستمر. يتميز بمؤشرات LED لمستويات المنطق والنبضات، ووظيفة حفظ النبضات. مثالي للمختبرات، واختبار الدوائر، والتعليم، والصناعات الإلكترونية.
The GLP-1A logic pulse can be used to perform in-circuit testing of TTL, CMOS, and many other logic devices at a maximum of 50MHz. The GLP-1A is enhanced with a logic probe function with a minimum detectable pulse width of 10 ns, providing enough sensitivity for most applications.
How to use:
- Connect the RED clip to the + terminal and the BLACK clip to the – terminal of the power source of the circuit under test.
- For TTL and DTL, set the upper select switch to the side marked “TIL”
- For CMOS, set the upper select switch to the side marked “CMOS”, and contact the probe pin to the point to be tested. The LEDs will indicate their logic states: A) ALL LEDs OFF -High impedance B) RED LED ON – High State (1) C) Green LED ON – low State (0) D) Orange LED ON – Pulse.
- For detecting and storing pulse or level transition, set the lower select switch to the side marked “PULSE” first. Contact the probe pin to the point to be tested. The LEDs will indicate its basic state. Then set the lower select switch to the side marked “MEM”, The orange LED will light when any pulse or level transition is detected. The pulse direction, in comparison with the original basic, state, cable determined. After use, reset the logic probe by setting the lower select switch back to the side marked “PULSE”
