  • Measuring Temperature Compensating Thermistors with the TEGAM Model 1830A RF Power Meter
    This document explains the theory behind measuring power with a dual bridge Power Meter such as the Agilent 432A and shows the reader how to simplify the measurement with the TEGAM 1830A RF Power Meter.
  • Output Standing Wave Ratio (SWR) Test Using the TEGAM 1830A RF Power Meter
    By utilizing a unique function that most modern power meters do not offer; the 1830A allows the user to change the value of the thermistor mounts terminating resistance. This application note will explain how we make this SWR measurement with the 1830A and a thermistor mount.
  • The Most Common Power Meter Mistake (.pdf)
    At least 50% of all power meter users make this mistake. It has happened to you. You measured an RF power level and later someone said, "...but I measured the power and got a different number." Who was right? Measuring RF power appears easy. Modern wattmeters and power meters are simple to use
  • How to Design Power Efficient Smart Gas and Water Utility Meters
    Designing a smart water or gas utility meter can present a vexing low-power challenge for embedded control systems requiring RF connectivity. Since a single service call from a technician often exceeds the entire cost of the smart meter, battery life must exceed 20 years. Learn more about how
  • Guide to RF Coaxial Connectors and Cables
    of items, e.g. RF generators, amplifiers, attenuators, power meters, couplers, antennas, etc., it is not uncommon that a great deal of thought is given to these "high end" devices while mundane items such as connectors and cables are often treated as an "afterthought".
  • Calculating a Calibration Factor
    When using an RF Power Meter with an RF Power Sensor to make an RF Power Measurement the user must know that the measurement is accurate and there is traceability to a known standard. All diode, thermo-electric, and thermistor power sensors have calibration factors associated to particular
  • 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
  • Using Agilent Temperature Compensated Thermistor Mounts with TEGAM Type IV Power Meters
    Thermistor-based RF power sensors are known by many names including thermistor mounts, thermistor sensors and bolometers. Thermistor sensors such as the Agilent (HP) 478A and TEGAM F1109 are dual thermistor based. In dual thermistor sensors, a pair of thermistor beads is used to detect RF power
  • Microwave or RF Amplifier Test Setup (.pdf)
    The sweeper generates a microwave frequency of 1.0 to 26.5 GHz with a leveled power output of up to +10 dBm. The power goes through the coupler to the Amplifier Under Test. 20 dB of the power is coupled to a Krytar Power Meter.
