Description OSCT-L Low Frequency Crystal Oscillator Tester For SMD 4P 2P Active Passive Crystal Oscillators Crystal Oscillator Tester: Provide test equipment for passive and active crystal oscillator testing, and perform signal conditioning on crystal oscillator output signal so that frequency meter can automatically detect. It can be combined with mechanical structure for pipeline testing. Typical Application: Practitioners: – Crystal oscillator sales, verification or screening of crystals in stock, purchase or sale; – Company Procurement: Sampling inspection of crystal oscillator; – For R&D personnel, select small batches of crystals or crystal oscillators for sample production, select crystal oscillators with better frequency stability or more accurate, and control product performance as much as possible. Industry Application: – Communication equipment manufacturers, screening crystal materials before production to avoid welding defective products on PCB circuit, such as software radio, wireless communication measuring instruments, Internet of things communication networking to accurately measure clock reference crystal; – Consumer electronics manufacturers, testing electronic products clock circuits, such as smart meters, computer motherboards, thermostats, timers, electronic scales, and precision measurement of timing functions on electronic cash registers; – Manufacturers of automotive electronic equipment, medical electronics, security electronics, industrial automation equipment, etc., verify or screen crystals that provide reference frequencies; – For teaching in colleges and universities, crystal screening can be used to deepen students’ understanding of crystal parameter indicators, and also to test materials to be produced; – Research products such as research institutes, select crystals with good consistency, and accelerate research and development of scientific research projects; – Manufacturers of quartz watch industry, commonly used 32.768kHz, the selection of quartz crystals, select crystals with more stable frequency, improve the accuracy of quartz watches; – Bank U-Shield or products sensitive to accumulated time error, calibrate crystal oscillator. Module Introduction: Technical Parameters: OSCT-L Low Frequency: – 32.768kHzï½32MHz (passive) – DCï½100MHz (active) – Power supply: DC 5V/1A – Active crystal oscillator power supply: * Internal: 3.3V/5V * External power supply: other power supply – Dimensions: 92 x 58 x 22 mm – Working Temperature: -20 to 45â – Storage Temperature: -20 to 70â – RF Interface: SMA-K(3-way) – Power Supply Port: Micro USB port Package Included: – 1 x Crystal Oscillator Tester Crystal Oscillator Test: For Testing Passive Crystal Oscillators: OSCT-L Version: 1.Test SMD Surface Mount Package: 5032(2P)/5032(4P)/3215(2P); 3225(4P)/2550(4P); Frequency range: 32.768kHzï½32MHz. 2.Test DIP In-Line Package: Dual in-line; Frequency range: 32.768kHzï½32MHz. For Testing Active Crystal Oscillators: 1.Test SMD surface mount package: 7050(4P)/5032(4P)/3225(4P)/2550(4P) Two groups. Frequency range: DCï½100MHz. Crystal Oscillators Test Steps: Test Passive Crystal Oscillators: a.In-line Package (DIP) 1.To determine measured crystal oscillator frequency, proceed as follows. No. 1: Frequency Range: 32.768 kHzï½1 MHz; Operation: For example 32.768kHz crystal oscillator. P5, P6 are connected with jumper caps. No. 2: Frequency Range: 1MHzï½32 MHz; Operation: P5, P6 disconnect the jumper cap. Picture: Passive crystal oscillator in-line package test area 2.Test passive in-line packaged crystal oscillator (DIP) in passive crystal oscillator test area, insert in-line crystal pins into crystal oscillator card holder, as shown in the figure above, press down on handle to clamp crystal oscillator. 3.With Micro USB 5V power supply, right DIP OUT SMA can measure crystal oscillator output signal. Attention: As shown in the above figure, 1 and 2 are all matching capacitors of in-line crystal oscillator. Default value is 15pF, and adjustable range is 5pF to 20pF. If there is no signal output from DIP OUT, crystal oscillator output signal can be obtained by appropriately increasing or decreasing matching capacitance according to crystal oscillator manual. b.SMD Package Picture: Passive crystal oscillator surface mount crystal oscillator test area 1.Put passive SMD crystal oscillator to be tested into corresponding package measurement area (5032(4p), 3225(4p), 2520(4p), 3215(2p), 5032(2p)), as shown in the figure above. Lightly press crystal oscillator to make good contact (mechanical tentacles can be used during automated testing). 2.To determine measured crystal oscillator frequency, proceed as follows. No. 1: Frequency range: 32.768 kHzï½1 MHz. Operation: For example 32.768kHz crystal oscillator. P7, P8 are connected with jumper caps. No. 2: Frequency range: 1MHzï½32 MHz. Operation: P7, P8 disconnect the jumper cap. 3.Powered by Micro USB 5V, crystal oscillator output signal can be measured by DIP OUT SMA on the right. Attention: As shown in the above figure, 1 and 2 are all matching capacitors of in-line crystal oscillator. Default value is 15pF, and adjustable range is 5pF to 20pF. If there is no signal output from DIP OUT, crystal oscillator output signal can be obtained by appropriately increasing or decreasing matching capacitance according to crystal oscillator manual. Test Active Crystal Oscillators: Active Crystal Oscillator Test Area: – Pin 1: 5V pin; – Pin 2: Crystal oscillator voltage (VCC) pin; – Pin 3: 3.3V voltage pin; – Pin 4: Ground (GND) pin; – Pin 5: Special voltage (the working voltage of crystal oscillator is not 5V or 3.3V). Active Crystal Oscillator Test Steps: 1.Put active patch crystal oscillator to be tested into corresponding measurement area of 7050, 5032, 3225, and 2520, as shown in the figure above. Lightly press crystal oscillator to make good contact (use a mechanical nozzle to touch the pressure during automated testing). 2.Crystal oscillator power supply options: Crystal oscillator 5V supply voltage: When crystal oscillator is powered by 5V, connect 5V (pin 1) and VCC (pin 2) in the figure below with a jumper cap; Crystal oscillator 3.3V supply voltage: When crystal oscillator is powered by 3.3V, connect 3.3V (pin 3) and VCC (pin 2) in the figure below with a jumper cap; Crystal oscillator external power supply: When crystal oscillator needs an external power supply, directly connect the positive pole of power supply to V external (pin 5), and the negative pole to GND (pin 4). Attention: – Choose only one crystal oscillator power supply voltage. Be careful not to short circuit (do not connect power supply to ground). – Powered by Micro USB 5V, lightly press crystal oscillator in the card slot, then crystal oscillator output signal can be measured on the right SMA.
