The Panther 9100 High-Speed Receiver is designed for high performance antenna testing where speed and accuracy are required. This two-channel system collects multi-port, multi-frequency data at 2 Million (2,000,000) measurements per second, while freeing the measurement application software from stringent timing requirements.

The Panther 9100 Receiver is capable of high-speed pulsed measurements of < 1 µs while improving on the high-performance specifications of the Panther 6000. The Panther 9100 Receiver includes a front panel LED "Phi" display capable of simultaneously showing amplitude, phase and beam state.

    The Panther 9100 improves on the Panther 6000 Receiver and high-speed beam controller to provide unparalleled speed for fast, accurate CW and pulsed measurements.

    • The Panther 9100 Receiver collects amplitude and phase data from its Test and Reference IF inputs, and transfers the amplitude and phase data directly to the host computer through a LAN interface. The receiver can be commanded to average measurements to increase dynamic range. It is compatible with frequency converter systems including Keysight's 85310A and NSI's IFC & DFC.
    • A high speed beam controller is integrated with the Panther 9100. The beam controller manages the critical timing for multi-port, multi-frequency measurements, relieving the host computer of exacting timing requirements. The Panther 9100 can control two sources and three 8-bit switches, and has TTL inputs and outputs for synchronization with external equipment. Maximum performance is achieved by using external hardware triggering to initiate beam controller operations. Software triggering is provided to allow operation without a hardware trigger. In pulse-mode antenna measurements, the Panther 9100 will synchronize to an incoming pulse, providing a programmable trigger delay to set the receiver trigger to the desired point along the pulse.

    NSI 2000 Antenna Measurement Software fully supports the advanced capabilities of the Panther 9000 System. For other applications, NSI provides a simple DLL programming interface, allowing integration of the Panther 9000 System with customer-supplied measurement application software.
