2.0 to 6.0GHz Instantaneous Frequency Measurement Unit DR076 2.0 to 6.0GHz Instantaneous Frequency Measurement Unit The DR076 uses proprietary Teledyne defence Technology to provide state of the art performance in a package measuring 130mm x 90mm x 18mm. configure the IFM during operation in order to achieve improved frequency resolution and accuracy when capturing longer pulses under poor SNR conditions. The DR076 provides a 13 bit absolute binary digital output word. The frequency measurement word is updated in response to an external trigger input signal, and internally generated trigger or is continuously updated every clock cycle. These operational modes are controlled via a serial control interface. The DR076 has a smaller frequency footprint and lower power consumption than traditional 2.0 – 6.0GHz IFM’s. The 13 bit frequency word offers a nominal resolution of 0.5MHz with an RMS accuracy of 2MHz for SNRs of +3dB or better. The unique feature of the DR076 is the ability to A PDW output is also available as an option.

Specifically, increased resolution and accuracies can be achieved for longer pulse durations. A number of modes of operation are available controlled via the serial control port, these include: Operating Mode Operation Standard Configured to measure minimum ppulse width (50 ns) Selectable PW Variable PW Trigger Mode Trigger Level Power Down Minimum pulse width is user selectable (50ns to ‘CW’). Unit measures longer pulses with improved accuracy and resolution. Unit performs measurements of pulse on continuous basis throughout the duration of the pulse. Subsequent measurements have improved resolution and accuracy. In this mode, frequency measurement accuracy is optimized on a pulse-by-pulse basis. Continuous Clocked Output: Frequency output word is updated at system clock rate. Externally Triggered: Frequency output word Is updated in response to rising edge of external trigger input. Internally Triggered: Frequency output word is updated in response to rising edge of internally generated trigger input (derived from internal pulse detection threshold circuit). The internal trigger level can be adjusted to optimize the POI and false alarms in the presence of injected noise or CW. Various power down modes can be configured reduce quiescent power consumption. The Variable PW mode uses Teledyne propriety techniques, and as such offers improved performance levels when compared with standard Instantaneous Frequency Measurement units currently available.
