Active Probe, 1 GHz
N2795A
General Purpose Probe
The N2795A is a new generation of low-cost, single-ended active probe with the AutoProbe interface. The probe integrates many of the characteristics needed for today’s general-purpose, high-speed probing - especially in digital system design, component design/characterization, and educational research applications. Its 1MΩ input resistance and extremely low input capacitance (1 pF) provide ultra low loading of the DUT. This, accompanied with superior signal fidelity, makes this probe useful for most of today’s digital logic voltages. And with its wide dynamic range (±8 V) and offset range (±8 V), the probe can be used in a wide variety of applications.

5G Active Antenna Innovator’s Kit
AWMF-0129
-
The AWMF-0129 is an active array for 5G wireless applications developed using planar antenna technology resulting in a very low profile, lightweight unit. The surface mount assembled antenna board is based on Anokiwave’s AWMF-0108 Silicon Quad Core IC and demonstrates the performance achievable using low power silicon integration and efficient antenna layout and design. Using the AWMF-0108, the antenna provides +50dBmi output power while consuming just 12W DC power in the RF circuits and has achieved Gb/s data rates in OTA trials. The electronic 2D beam steering is achieved using analog RF beam forming, with independent phase and gain control in both Tx and Rx operating modes. The AWMF-0129 antenna leads the way in showing how 5G coverage can be rolled out by network operators using the mmW bands, with low power footprint and high energy efficiency, while meeting key operating specifications for data rate, latency, coverage, and reliability.

Mid-Range Gas Filter Correlation CO Analyzer
Model T300M
-
Teledyne Advanced Pollution Instrumentation
The Model T300M CO analyzer measures low to mid ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.

High Impedance Active Probes
7
-
Designed as a companion probe to Models 12C and 18C for driving integrated circuit lines so the Model 12C and 18C can be used to measure the response of adjacent nodes. The Model 7 consists of a flexible 6 foot, 50 ohm coaxial cable accurately terminated to 50 ohms in order to avoid undesirable reflections. A special miniature connector receives replacement coaxial probe tips that provide a shielded environment to within 3 mm of the fine tungsten probe point, thus minimizing capacitive coupling to other parts of the circuit. The replaceable coaxial probe tips are offered in various point sizes and can also be bent to any shape in order to accommodate a variety of probing geometries.

Mid-Range Gas Filter Correlation CO2 Analyzer
Model T360M
-
Teledyne Advanced Pollution Instrumentation
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.
