Operating between 4V and 18V DC and handling input frequencies up to 50MHz, it offers versatile, high-speed diagnostics with global plug compatibility. ## Description The GLP-1A logic pulser can be used to perform in-circuit testing of TTL, CMOS, and many other logic devices at a maximum of 50 MHz. 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. A Short 10 sec pulse width assures that no damage will occur to circuits whilst testing. With a weight less than 50g, a non-slip grip, and an external sync input, GLP-1A provides comfort and reliability for various troubleshooting tasks. Display: 8 digits with Hz, kHz, MHz, GHz, s, ms, microseconds, and overflow. Gate time: Variable from 10ms to 10s, or 1 period of input depending on whichever is greater. Accuracy: +/- (resolution +/- timebase error). Channel A: Range: DC coupling: 0.01Hz to 120 MHz, AC coupling: 30Hz to 120 MHz. Sensitivity: 10mV typical, 50mV maximum. Coupling: AC or DC, selectable. Filter: Low pass, selectable in or out for channel A (-3dB point, nominal 100kHz). Impedance: 1 megohms//40 picofarad. Attenuator: 1/1 or 1/20dB. Trigger level: -2.5VDC to +2.5VDC. Adjustment resolution: For frequency measurement, the maximum resolution is 100nHz for 1Hz and 0.1Hz for 100 MHz inputs respectively. For period measurement, the maximum resolution is 10ns for 1Hz input, and 0.1x10-15s for 100 MHz inputs respectively. Display accuracy: 7 digits for 1 sec gate time, 6 digits for 100ms gate time, 5 digits for 10ms gate time. Power Source, 100 MHz Bandwidth: 100V/120V/220V/230V +/- 10 percent, 50/60Hz AC. Measures 230mm width by 95mm height by 280mm depth. ## Features - item package contains both UK and EU plugs - Combining a logic probe and pulser combined into one - Probe for troubleshooting digital circuits - Operating voltage: 4VDC to 18VDC - Maximum input signal frequency: 50 MHz - Pulser: sync input impedance 120 kilo-ohm ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | GW Instek | | Part number | GLP-1A | | Item Weight | 0.28 g | | Product Dimensions | 1.8 x 1.8 x 21 cm; 0.28 g | | Item model number | GLP-1A | | Power source type | Battery Powered | | Item Package Quantity | 1 | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** GW Instek - **Power source:** Battery Powered - **Item weight:** 0.01 Ounces - **Item dimensions L x W x H:** 18 x 18 x 210 millimetres - **Maximum operating voltage:** 18 Volts ## Images ![GW Instek GLP-1A Logic Probe and Pulser, 4VDC to 18VDC Operating Voltage, 50MHz Maximum Input Frequency - Image 1](https://m.media-amazon.com/images/I/417mCe6ki1S.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not for 3.3V logic! *by P***N on 12 November 2017* Don't make the same mistake as me: this won't work for 3.3V logic (Raspberry Pi, Arduino, etc.) It says clearly in the description that it works down to 4V, but no lower. Nobody to blame but myself... ### ⭐⭐ Not quite what it says *by C***E on 21 November 2016* The product details said it had an 8 digit display and implied that it could measure frequency. That is incorrect, it is just a logic probe and pulser. ### ⭐⭐⭐⭐⭐ Five Stars *by P***R on 27 August 2017* Good logic probe with extra features, use it nearly everyday. ## Frequently Bought Together - GW Instek GLP-1A Logic Probe and Pulser, 4VDC to 18VDC Operating Voltage, 50MHz Maximum Input Frequency - 4PCS Breadboards Kit Include 2PCS 830 Point 2PCS 400 Point Solderless Breadboards for Proto Shield Distribution Connecting Blocks - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/50887388-gw-instek-glp-1a-logic-probe-and-pulser-4vdc-to](https://www.desertcart.com.cy/products/50887388-gw-instek-glp-1a-logic-probe-and-pulser-4vdc-to) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-23*
