Product Description
The DR058 utilises proprietary Teledyne Defence Limited (TDL) technology to provide state of the art performance in
a package measuring only 152mm x 147mm x 30mm and weighing 1.55kg.
The DR058 is a clocked sampling IFM, providing a digital 12-bit output word of the RF input frequency for each clock
cycle. An external trigger will force a sample to be taken asynchronously. The internal analogue bandwidth is sufficient
to capture a 50ns pulse.
With a resolution of 12 bits, the DR058 gives a nominal frequency resolution of 3.93MHz and an rms accuracy of
≤4.5MHz with an input SNR of 3dB or better.
Designed specifically for fast jet applications, this product will withstand the most demanding of environments. It is
characterised for –40ºC to +85ºC. For applications outside this range, please contact the TDL sales team.
External connections are made via a 51 way high density D type for power and digital I/O and SMA for the RF input.
This product is recommended for new designs. Other IFM configurations are available and for further information,
please contact the TDL Sales Team.

Nominal frequency resolution is unambiguous bandwidth divided by number of bits.
See timing diagrams. Based on a 40 MHz clock.
Minimum SNR required for nominal operation.
Minimum pulse width is defined by internal video bandwidth.
Given as the maximum time required between the removal of a pulse of RF at any power within the operating
dynamic range and the arrival of the next pulse to ensure the correct measurement of the second pulse.
The actual resolution, i.e. the change of frequency required to change 1 bit of the output word varies with frequency. The rms accuracy is calculated as the standard deviation of the frequency distribution. The rms accuracy is specified for 3dB and 0dB input SNR. The rms error excludes those measurements that are flagged as “bad data”.
The percentage number of measurements that exceed the peak error frequency.
The percentage number of measurements that cause the ‘bad data’ signal to be asserted.
Simultaneous signals are defined as signals which overlap by at least 30ns during a measurement cycle. A valid
measurement will be made on the larger of two signals provided that a) the amplitude difference between them
is 10dB and b) there is at least 100MHz frequency separation.
Maximum input power without damage.

Note 1 If a second pulse starts within this period the frequency measured may not be correct.
Note 2 This timing will ensure that the frequency within a 50 ns pulse is measured correctly..
When no external trigger is supplied, but RF is present, the device will run in continuous clock mode. The rising
edge of ExtTrigger causes the digitized tier video data at the front of the pipeline to be held (frozen) after a delay
of approximately 25 ns (to allow video to settle) for a minimum period of 1 clock cycle to guarantee that this data
enters the pipeline at the next rising clock edge.
