2 to 18GHz Instantaneous
Frequency Measurement Unit
DR058
2 to 18GHz Instantaneous Frequency Measurement Unit
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 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.
With a resolution of 12 bits, the DR058 gives a nominal
frequency resolution of 3.93MHz and an rms accuracy of 4.5MHz
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.
