0.5 – 2.4GHz Instantaneous Frequency Measurement Unit DR063 0.5 to 2.4GHz Instantaneous Frequency Measurement Unit The DR063 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 DR063 provides a 12 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 interface. The DR063 has a smaller frequency footprint and lower power consumption than traditional 0.5 – 2.4GHz IFM’s. The 12 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 DR063 is the ability to For further information, please contact the TD sales team.

A number of modes of operation are available via a serial interface, these include: Operating Mode Operation Standard Configured to measure minimum pulse width (50 ns) Selectable PW Variable PW Trigger Mode 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 optimised 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.) Trigger Level Power Down The internal trigger level can be adjusted to optimise 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.

Clean Signal Fig 2. 0dB SNR Fig 3. RMS Error vs. SNR Figures 1 & 2 show typical performance achieved in clean signal and 0dB SNR respectively. Although these test were performed with CW signals, the performance with 50 ns pulses is only marginally reduced. Figure 3 shows how RMS frequency errors can be reduced when selectable pulse width mode is used. A 1 us pulse is measured with improved accuracy over a system configured to measure 50 ns pulses. Furthermore, pulses are measured reliably in negative SNR conditions.
