[0018] FIG. 1 illustrates a hardware configuration according to a first embodiment 1 of the present invention. As shown, the mixers 11 and 13 receive low-band and high-band signals from one signal input connector (not shown). A source 15 (eg local oscillator) also feeds the mixer via routing relay K8, which may also be a power divider. The resulting IF signal output from mixer 11 or 13 is applied to routing relay K7, and after passing through additional circuitry via routing relay K1 or K2, K7 preferably multiplexes each output IF signal one at a time into a single digital converter (not shown), as described below.

[0019] After passing through the routing relay K7, the selected signal passes through a low-pass filter 17 and a high-gain amplifier 19 . The output of high gain amplifier 19 is split such that the signal passes through two different sets of circuit components (indicated by dashed boxes 20a and 20b). In the first group of components 20a, the relay K6 applies a ...

[0024] The configuration of the equipment in the second embodiment 2 is slightly different from that of the first embodiment, the difference is that, as shown in Figure 2, the routing relay K5 is placed between the routing relays K2 and K3. According to this second embodiment, it is possible to simultaneously feed the outputs of detectors 37 and 41 to the inputs of separate digitizers connected to routing relays K1 and K2.

[0025] image 3 Shown are exemplary steps of a software algorithm or a hardware-implemented process for implementing a synthesized RF detector by constructing a synthesized waveform in accordance with the present invention. In the first embodiment of the present invention, the process described below is performed after the data from the linear detector 37 and the logarithmic detector 41 are digitized by the digitizer and recorded or stored. In the second embodiment, since both detectors can be simultaneously monitored by independent digitizers, the collect...

Abstract

Outputs of a linear RF detector and a logarithmic RF detector are multiplexed individually to a single digitizer or simultaneously to a respective digitizers. A process generates a composite waveform from the resulting digitized data, either at a later time in the former case or in real-time in the latter case. To achieve simultaneous routing, several routing relays are arranged in a specialized configuration between the outputs of the RF detectors and the inputs of the digitizers.

Description

[0001] This application claims priority to US Provisional Patent Application No. 60 / 407,982, filed September 5, 2002, the disclosure of which is incorporated herein by reference in its entirety. technical field [0002] The invention relates to the arrangement and installation of radio frequency detection equipment. More specifically, the present invention relates to improved network analysis device configurations and methods for detecting pulsed RF signals. Background technique [0003] In some types of RF testing, it is sometimes necessary to measure / detect pulse modulated RF signals with high on-off ratios, eg greater than 70dB, with high RF level signals in the on state. An example of such testing, conducted by the assignee of the present invention, is in conjunction with a program designated RAH66, the designation for the Comanche Helicopter program of the United States Department of Defense. An RF test in this case employs the Radio Frequency Portable Maintenance Aid ...
