-
Precise Time and Frequency, Inc.
The ptf 1230A(1U)/1231A(2U) GPS L-Band RF Distribution amplifiers provide high performance GPS signal references for laboratory or systems use. In most applications the low noise and signal gain capability of the units will provide userswith a robust GPS signal source for lab or system requirements.The ptf 1230A/1231A uses individually buffered output stages and insures maximum isolation between the individual outputs. The ptf 1231A offers 12 outputs. Options are available for a 2U/3.5” version (ptf 1230A) with 24 outputs.Isolation from output to output is >-40 dB. The input also offers DCV for biasing an active antenna.

Frequency Response Analyser
DP-cPCI-7554
-
DP-cPCI-7554 is a cPCI module capable of analyzing the phase and gain characteristics of a system. The system under test is stimulated by the user defined waveform. The obtained response is correlated with the applied stimulus by the on-board DSP processor to determine the phase difference and the gain.Gain and the face analysis is carried out only at sine waveform.

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.

Erbium Fiber Frequency Comb
-
Detailed description of item: The AOSense frequency comb is a low noise, polarization maintaining (PM) device. Key features include a PM fiber architecture centered at 1550nm with turnkey modelocking; a free-running linewidth of the carrier-envelope offset frequency of <200 kHz; a temperature-insensitive all-fiber f-2f interferometer exhibiting fceo beatnotes with SNR > 45dB (300kHz RBW); and dual fast/slow cavity length actuators with a bandwidth of >300 kHz. The repetition rate of the comb is factory set and allows matching across multiple combs for dual comb applications. The optics package incorporates an optical heterodyne module designed for locking to the comb to an ITU-specified laser reference. The comb is capable of supporting an Allan deviation of < 5 x 10-18 at 1 second and ~10-20 after 105 seconds. Add-on features include all fiber extensions to visible wavelengths corresponding to several atomic transitions. An integrated comb electronics package is currently under development.
