Frequently Asked Questions

• How do I adjust the bandwidth of my CATV equipment?

  To edit the bandwidth, press the BWsoft key. The bandwidth can be adjusted by using the up and down diamond keys or by entering a value using the numeric keypad and then pressing the Enterkey. The FCC specification for C/N measurements is a bandwidth of 4.2 MHz. CATV organizations outside of the United States may have different requirements.

• What is the WWG cable modem C/N instrument feature?

  To overcome the confusing test equipment set-up process, WWG has introduced a new instrument feature that allows technicians at all skill levels to perform accurate return-path cable modem C/N measurements. Why Measure Cable Modem C/N?

• How do you set the telemetry for a sweep receiver?

  On the receiver select (CONFIGURE; SWEEP RECEIVER) and set the forward sweep telemetry frequency to be the same as the Tx and/or Rx. Also set the reverse sweep insertion and telemetry levels as close to the system specifications as possible, taking into consideration insertion losses.

• What is proposed gas leakage monitoring system?

  Proposed model notifies alert to people before any leakage from the gas cylinder and also automatically books for refilling of gas from the gas booking centre before the cylinder gets empty. Figure. Gas leakage Monitoring system block diagram.

• What are the flow charts for gas leakage detection?

  There are two flow charts for gas leakage detection and automatic gas booking which explain the methodology of the operation as follows: In this model, gas spillage recognition has been given a most elevated need.

• How does a gas leak detection system work?

  If gas leakage occurs, this system detects it and makes an alert by buzzing the buzzer attached with the circuit. This system is easy to build and anyone who have some knowledge of electronics and programming can build it.

• What is the main objective of the LPG leakage research?

  The main objective of this research is automatic protection from the LPG (Liquefied Petroleum Gas) leakage or reduction of the hazards that can be caused due to unawareness of the user about the gas leakage and also providing an automatic gas booking facility by applying advance communication technology.
