NI
2-Channel, 8 V, ±3 A PXI Programmable Power Supply—The PXIe‑4154 is a specialized programmable power supply for battery simulation. It is designed to simulate a lithium‑ion battery cell’s transient speed, output resistance, and 2‑quadrant operation (source/sink). Critical to many RF and wireless applications, the simulator’s fast transient response time allows it to rapidly respond to changes in load current with minimal voltage dip, which makes the PXIe‑4154 ideal for powering devices under test (DUTs) such as RF power amplifiers, cellular handsets, and a variety of other mobile devices. To model the behavior of a battery more accurately, you can use the onboard programmable output resistance to simulate a battery’s internal resistance. For quiescent and standby current measurements, the PXIe‑4154 features integrated current measurement.

M9451A -
Keysight Technologies
The M9451A PXIe Measurement Accelerator combined with Option DPD Digital Pre-Distortion & Envelope Tracking Gateware shows what is possible when you combine state of the art FPGA's with Keysight's trusted measurement expertise and PXIe's high speed data handling. As part of Keysight's RF PA/FEM Characterization & Test, Reference Solution, this combination provides unprecedented performance for demanding envelope tracking and digital pre-distortion measurements required for testing modern power amplifiers (PAs) and front-end modules (FEMs). Hardware acceleration provides better than 20x speed improvement over Keysight's previous host-based Reference Solution, with closed/open loop digital pre-distortion (DPD) and envelope tracking (ET) measurements taking just tens of milliseconds and overall measurement times less than 70 ms.

HIGH-POWER RADIO FREQUENCY (RF) AND MICROWAVE AMPLIFIERS, TWTA AND SOLID STATE -
Communications & Power Industries
electromagnetic compatibility (EMC) high-intensity radiated field (HIRF) testing, military testing, electronic warfare simulation and scientific applications are based on the same switched-mode power supply technology as its rugged amplifiers. As a result, these instrumentation amplifiers have all the same performance and reliability advantages as the rugged product line, but have been neatly re-packaged into compact, lightweight and affordable rack-mountable units more suitable for less demanding physical environments. CPI TMD's new modular design (the PTCM range) has many user benefits, including advanced self-diagnostics, ethernet interfaces, remote management, VSWR protection and plug and play field replaceable power supplies.

DCNTS -190 -
Eastern-Optx
The DCNTS is a two channel Phase and Amplitude noise analyzer. Its dual demodulator architecture allows the system to use cross-correlation to cancel its internal noise and limitation; it is like comparing the outputs of 2 systems and only display the similarities while rejecting differences. Its main extension is the Residual Noise measurement front-end which includes all necessary hardware to automatically measure residual noise on 2-ports devices either in RF frequencies or microwave. It could be a frequency multiplier or divider, an amplifier or any other phase coherent input to output device.

ICE3009 -
Pole/Zero
The ICE3009 subsystem is an agile filter for the VHF-L, VHF-H and UHF frequency bands. It allows operation of a number of transceivers in a cosite environment. The VHF/UHF Filter provides multiple poles of RF selectivity to reduce broadband noise in transmit mode of operation and to reduce interfering signals at the transceiver’s RF input in receive mode at Have Quick II/IIa and SATURN tuning speeds. This design incorporates a flexible control scheme that can be configured at the factory for various radio interfaces (ARC-210, ARC-231, ARINC 429, etc.). The design is highly integrated and includes all filters, amplifiers, power supply, transmit and receive switching (including a bypass mode), and Built-in-Test (BIT). A mounting tray is available as an option for easy incorporation on your platform. This system is qualified for military applications. Cost-effective modifications are available on the ICE3009. Please contact your sales representative at 513.870.9060 or Support@PoleZero.com for details.

HFDF -
National RF, Inc
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.
