"TB13 - How Is the Center Frequency of a Monocycle Waveform Measured?" at http://www.avtechpulse.com/appnote/techbrief13/ for information about center frequency measurements. The AVB1-3 can operate at repetition rates of up to 100 kHz. An externally-generated TTL-level signal is required to trigger the AVB1-3. The AVB1-3 is powered by +15V DC.
1) May be tuned either by front-panel one-turn control or by applying 0 to +10 Volts DC to a solder terminal. Input impedance greater than 10 kilohms. 2) A 50 Ohm load is required. Other loads may damage the instrument. Consult Avtech (info@avtechpulse.com) if you need to drive other load impedances.
GENERAL INFORMATION BASIC TEST ARRANGEMENT The AVB1-3 should be tested with a sampling oscilloscope with a bandwidth of at least 2 GHz to properly observe the high-speed waveform. A typical test arrangement is shown below: SYNC OUTPUT TTL-LEVEL +3V to +5V (TTL)
CONTROLS FREQ TRIG The “OUT N” and “OUT P” SMA connectors are connected to the pulse combiner on the top of the main module, through factory-installed cabling. The external trigger is applied to the TRIG input connector. The input impedance is ≥ 1kΩ.

2) The use of a 40 dB attenuator will ensure a peak input signal to the sampling scope of less than one volt. 3) The module shown should be bolted to a heat sink capable of dissipating at least 5 Watts. 4) Various settings are sensitive to variations in the +15 VDC voltage supply and therefore a well-regulated DC supply is required.
