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

TECHNICAL INFORMATION
The ability for the DR063 to be configured on the fly to suit operational scenarios offers performance attributes
unmatched by currently available IFMs. Specifically, increased resolution and accuracies can be achieved for
longer pulse durations. 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.

BLOCK DIAGRAM
Fig 1. 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.
