1) -C suffix indicates stand-alone lab instrument with internal clock and line powering. (See http://www.avtechpulse.com/formats for additional details of the basic instrument
formats).
2) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -P-PN or -N-PN for dual polarity option where the suffix preceding -PN
indicates the polarity at the mainframe output port.
3) For DC offset option add suffix -OS.
4) For units with the -ECL option, an ECL logic level pulse (i.e., -1.6V = ECL LOW, -0.8V = ECL HIGH) is required to trigger this input, and the input impedance is 50 Ω to -2V.
5) 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.
6) For operation at amplitudes of less than 20% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external attenuators on the
output.
7) Maximum amplitude falls by 10% for PRF above 20 MHz.
8) The FWHM pulse widths (i.e., at the 50% rise point) are lower. For example, the minimum FWHM pulse width for the AVMH-1A-C series is < 100 ps. Please see the
typical test waveforms on the web site for actual results from shipped units.
9) An input impedance of ≥1 kΩ can also be provided (-Z1K option).
10) For monitor option add the suffix -M to the model number.
