Abstract: An insulating container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching devices, in the closed configuration. In some examples, the insulating container further includes a pull handle assembly with a telescopic three-stage arm configuration defined by a stowed configuration, a partially extended configuration, and a fully extended configuration. In other examples, the insulating container further includes a wheel assembly with a pair of wheels mounted with one or two axles, and further including a wheel grommet for absorbing shock and cushioning the axle. In still other examples, the insulating container further includes a drain plug assembly on the rear sidewall adjacent to the bottom portion of the base, the drain plug assembly comprising a main tube that cooperatively engages with an outer tube with a plurality of ratchet teeth that engage one or more ratchet keys on the main tube.

Abstract: An instrument which provides a measurement of the frequency and power of a microwave signal supplied to an input port of the instrument. The instrument includes: a resistive device which divides the microwave signal supplied into first and second microwave divisions thereof; a frequency counter which measures the frequency of the first microwave division, thereby providing the measurement of the frequency of the microwave signal supplied; and a power sensor and power meter combination which measures the power of the second microwave division. The power sensor and meter combination makes a calibration correction dependent on the frequency measured by the frequency counter to its power measurement, thereby providing the measurement of the power of the microwave signal supplied.

Abstract: Disclosed is a Device Under Test (DUT) fault detection and location circuit. A first circuit port is connected to the DUT for fault detection and location. A signal source for generating a series of signals across the operating frequency range of the DUT is connected to a second circuit port. A divider divides each signal generated by the source so as to provide first and second fractions of the signal, the second fraction passing to the device under test. A fault detection section provides a DUT fault detection voltage for each respective frequency. The circuit also has a branch including an impedance section and a fault location section. The branch receives the first fraction, and the fault location section provides a DUT fault location voltage for each respective frequency.
