  • Understanding In-Line RF Power Measurements
    requires probable accuracy of the meter being used. This article describes two commonly used methods of detecting rf power and the implications of using those methods in a plasma system environment. The descriptions for these two detection methods apply to both an rf generator's internal power
  • Selecting Antenna/Power Amplifier Combinations for the Coming New RF Immunity Standards
    candidate for the upper frequency for consumer products. When test facilities test products for compliance to these new RF immunity standards, which antenna/amplifier combination will prove the most effective at producing the necessary volts per meter over the new band? What is the cost-benefit

    in receive mode. Current consumption in transmit mode depends on output power but is less than 30 mA at 10 dBm. Typical applications include home automation, wireless security systems, meter reading, and toys. The CC1000 is generally intended for use over short ranges. It operates at 315, 433, 868

    meter (Figure 2). Figure 2. Cutaway view of a typical, axially-mounted turbine meter. Either a magnetic or modulated carrier (RF) pickoff can be used to sense the rotation of the turbine rotor and provide an electrical output that is proportional to the flow rate. The RF pickoff extends the low flow
  • Capacitor Testing Procedures
    Capacitors for applications involving applied DC voltage should be tested on a DC dielectric strength meter for voltage and emission current. Jennings will test capacitors to this measure if specified by the customer. Jennings Technology - Technotes - Vacuum Relays, Vacuum Capacitors, Vacuum
