Improved coaxial connectors and methods which have enhanced characteristics, reliability, strength, and durability. This coaxial connector system uses a flange mating system and a single slot male pin center conductor contact. The flanges use precision guiding pins and screws to axially align and secure the mating flanges together. The coaxial center conductors are electrically connected to each other by a resilient, single slotted, formed male pin and a female receptacle as center conductor assemblies. When the two flanges are fastened together, the center conductor assemblies (formed male pin and a female receptacle) mate to form an electrically conducting connection.

A method for measuring electrical response of a DUT includes using a measurement instrument, generating a radio frequency (RF) test signal via the measurement instrument at one or more initial frequencies, propagating the RF test signal at the one or more initial frequencies to the DUT, measuring a response of the DUT at the one or more initial frequencies and aggregating the measured response of the DUT at the one or more initial frequencies as response measurement data. The method then includes iteratively performing, until characterization of the DUT achieves a minimum criterion, the steps of adaptively selecting an additional frequency at which to generate a RF test signal based on the response measurement data based on a predetermined adaptive frequency algorithm, generating the RF test signal at the adaptively selected additional frequency, measuring a response of the DUT at the adaptively selected additional frequency, and adding the measured response of the DUT at the adaptively selected additional frequency to the response measurement data.

A coaxial connector system is provided suitable for connection of high-frequency components such as high-band test modules and probes. The coaxial connector system uses a flange mating element aligned using precession guiding pins. A center conductor assembly is captive in a center bore of the flange and includes elastomer contacts which are compressed against the coaxial center conductors of the high=frequency components. The flange mount coaxial connector system provides a robust, mechanically stable mount which minimizes electrical performance changes with mechanical torque as compared to screw on connectors.

A system for measuring an electrical response of a device under test (DUT) includes a reflectometer with reduced heat dissipation used with a vector network analyzer (VNA). The reflectometer is tethered to the VNA using a tether of scalable length which carries low frequencies. The reflectometer has a distributed harmonic generator including a non-linear transmission line (NLTL) for multiplying a frequency of an RF signal received from the VNA to generate a test signal having a frequency in the millimeter wave range at a test port connected to the DUT. A sampler in the reflectometer receives a local oscillator (LO) signal from the VNA and includes another NLTL for receiving the LO signal and generating pulses at a frequency in the millimeter wave range. When the test signal is transmitted to the DUT, the sampler outputs intermediate frequency signals which are transmitted to the VNA for characterization of the DUT.

In an embodiment, a system for measuring high frequency response of a DUT having improved power leveling includes a signal source, a modulator, an upconverter, and a leveling loop having dynamic gain adjustment. The signal source generates a test signal and the modulator modulates the amplitude of the generated test signal to target a requested power. The converter multiplies a frequency of the test signal. The leveling loop is configured to detect an intermediate frequency (IF) signal generated in response to the upconverted test signal. Modulation of the amplitude of the generated test signal by the modulator is adjustable based on the IF signal detected by the leveling loop.

Systems in accordance with embodiments of the present invention can include an adapter having a sliding portion (a slider) slidable to expose an interface, thereby allowing mating&#x2014;for example, between a test port and a DUT&#x2014;to be observed and adjusted as required. The slider is removable, allowing an adapter sex change. In one embodiment, an insertion tool is provided which can hold a dual male pin and allow installation and removal of the dual male pin while assisting mating alignment. After calibration, the slider can be locked in place and the adapter can function as a standard coaxial connector.

A steam coil apparatus for transferring heat between steam passing through the apparatus and air flowing past the apparatus, the apparatus including a plurality of spaced outlet tubes extending substantially parallel to one another in a direction generally transverse to the direction of flow of the second fluid, and a plurality of fins or other extended surface attached to the outlet tubes and extending generally transverse to the outlet tubes. A plurality of inlet tubes are provided, each being received within one of the outlet tubes and formed of a diameter smaller than the diameter of the outlet tube within which it is received. The inlet tubes are provided with axially spaced orifices through which the first fluid passes from the inlet tubes to the outlet tubes. An outlet header is provided in fluid communication with the outlet tubes, and first and second opposed inlet headers communicate with the inlet tubes. The first inlet header communicates with a first set of the inlet tubes and the second inlet header communicates with a second set of the inlet tubes, wherein each inlet tube of the first set is spaced from each adjacent inlet tube in the first set by an inlet tube of the second set.
