Item Description: The scope of this module: 1 is used as a square wave signal generator generates a square wave signal used for experimental development. ... more2 to drive a stepper motor for generating a square wave drive signal. 3 adjustable pulse generated for use by MCU. 4 adjustable pulse generation. Control circuitry associated. a brief description: 1. Size: 3.1CM* 2.2CM 1. The main chip: NE555; 2. Input voltage: 5V-15VDC. 5V power supply, the output current can 15MA around; 12V power supply, the output current can 35MA around; 3. The input current: ≥ 100MA 4. The output amplitude: 4.2V V-PP to 11.4V V-PP. Different depending on the input voltage, the output amplitude will be different) 5. The maximum output current: ≥ 15MA(5V power supply, V-PP greater than 50% ≥ 35MA(12V power supply, V-PP greater than 50% Advantages: 1. The output with LED indication, there is no output straightforward(low LED volume, high LED off frequency is relatively low, the LED flashes) 2. The output level selectable frequency range, the output frequency is more continuously adjustable; LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High-frequency file: 1KHz ~ 10kHz HF file: 10kHz ~ 200kHz. 3. The output duty cycle can fine-tune, duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency. 4. The output frequency is adjustable; Period T = 0.7(RA +2 RB) C. RA. RB is 0-10K adjustable; Low profile when C = 0.001UF; IF stalls C = 0.1UF; High-frequency file C = 1UF; HF stalls C = 100UF. So the frequency of the waveform buyers can own calculations. We maintain high standards of excellence and strive for 100% customer satisfaction! Feedback is very important to us. We request that you contact us immediately BEFORE you give us neutral or negative feedback. So that we can satisfactorily address your concerns.

Acterna ... moreHST-3000 SIM ADSLR Service Interface Module Working Condition: Excellent Condition: Refurbished Warranty: 90 Day Exchange Warranty ADSL is designed to carry a digital signal. Over a copper pair, above the voice frequency band(20 KHz–1.1 MHz) to enable high speed internet service over a standard POTS line. This allows“always on” internet access while simultaneously providing voice service. Typical POTS line quality will normally support ADSL, but the DSL service must be tested when trouble strikes. To troubleshoot DSL service, a modem emulation test set, such as the HST-3000, is needed. The DSLAM and network configuration is verified by connecting at the main distribution frame(MDF) where known interference and attenuation are minimal, as shown in Figure 1. The physical(ADSL) layer data rates and noise margins are reviewed to confirm that they match the service contract. Validate correct DSLAM and BRAS provisioning by connecting to the customer line and authenticating with the network through the DSLAM. The HST-3000 ADSL testing features use modem emulation(ATU-R Annex A or Annex B) to turn up and troubleshoot ADSL and ADSL2 services as well as provide ATM statistics and analysis. The internet protocol(IP) suite software allows IP/PPP troubleshooting. The on-board web browser option validates an internet connection. The capabilities of the ADSL features include the following: Variety of ADSL testing modes for service verification. Local loop testing, and network connectivity: Mode Function ADSL Modem emulate mode Used to test basic ADSL physical layer rates. Quality and line statistics. Also used for testing the following types of lines: IP over Ethernet. IP over ATM, PPP over Ethernet, and PPP over ATM. ADSL Through mode Used for testing the following types of lines: Bridged Ethernet. IP over ATM, PPP over Ethernet, and PPP over ATM. ATM Loopback Used
