2 to 18GHz Instantaneous Frequency Measurement Unit DR024-M4 2 to 18GHz Instantaneous Frequency Measurement Unit The DR024-M4 utilizes proprietary Teledyne Defence Limited (TDL) technology, to deliver state of the art performance in a package measuring only 152mm x 147mm x 30mm and weighing only 1.55kg. The DR024-M4 is can be externally or internally triggered and provides a digital 12-bit output word of the RF input frequency with every sample. The internal analogue bandwidth is sufficient to capture a 50ns pulse. With a resolution of 12 bits, the DR024-M4 gives a nominal frequency resolution of 3.93MHz and an rms FEATURES • • • • • • • • 12 Bit Resolution External or Internal Trigger 50ns Pulse Capable 16GHz Instantaneous Bandwidth -50dBm Sensitivity Small Form Factor Low Weight Low Power Consumption accuracy of ≤4.5MHz with an input SNR of 3dB or better. Designed specifically for fast jet applications, the DR024M4 will withstand the most demanding of environments. It is characterized for -40ºC to +85ºC. For applications outside this range, please contact the Sales Dept. External connections are made via a 51 way high density D type for power and digital I/O and SMA for the RF input. Other IFM configurations are available and for further information, please contact the TDL Sales Team.

See timing diagrams. Minimum SNR required for nominal operation. Minimum pulse width is defined by internal video bandwidth. 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”. 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.
