The Panther 6000 Receiver System is designed for high performance antenna testing where speed and accuracy are required. This two-channel system collects multi-port, multi-frequency data at up to 80,000 measurements per second, while freeing the measurement application software from stringent timing requirements.

The Panther 6000 System consists of two units that work together to provide fast, accurate measurements:

• The Panther 6001 Receiver collects amplitude and phase data from its Test and Reference IF inputs, and transfers the digitally processed data directly to the host computer through a PCI-bus interface card. The receiver can be commanded to average measurements to increase dynamic range. It is compatible with frequency converter systems including Agilent's 85310A and NSI's Integrated and Distributed Frequency Converters.

• The Panther 6002 High Speed Beam Controller (HSBC) manages the critical timing for multi-port, multi-frequency measurements, relieving the host computer of exacting timing requirements. This unit can control two sources and three 8-bit switches, and has TTL inputs and outputs for synchronization with external equipment. In pulse-mode antenna measurements, the HSBC 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 v4.0 Antenna Measurement Software fully supports the advanced capabilities of the Panther 6000 System. For other applications, NSI provides a simple DLL programming interface, allowing integration of the Panther 6000 System with customer-supplied measurement application software.
