Frequency Synthesiser
RA062-F2
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.

Frequency Shaped Isotropic Electric Probes
PI-SH-FCC, PI-SH-ICNIRP
An isotropic electric field probe with shaped frequency response meeting the ICNIRP or FCC RF safety standards for occupational and general public exposure limits (see the specified frequency ranges below). Meter readings are shown in % of the STD – standard reference level, eliminating the need to know the source frequency. Probe output is proportional to RF power density in the whole specified power range, producing the correct RF power measurements in single and multi-signal environments, typically present at multiple antenna sites.
