Other settings should be as shown in the ab ove diagram. 5) W ARNING: Model AVMR-2 may fail if triggered at a PRF greater than 10 MHz or if the duty cycle exceeds 20% or if the PW exceeds 200 nsec. 6) The output amplitude is controlled by means of the one turn potentiomet er (Amp). 7) The output pulse width is controlled by means of the one turn potentiom eter (PW). 8) The required output DC offset voltage is applied to the rear panel OS s older terminals ( 50 Volts, 100 mA max). 9) For high duty cycle operation, it is recommended that the unit be bolte d to a heat sink capable of dissipating at least 10 Watts. 10) For additional assistance: Tel: (613) 226-5772 Fax: (613) 226-2802 Email: info@avtechpulse.com __________________________________________________________________ 7 PERFORMANCE CHECK SHEET __________________________________________________________________ Document Outline * [1]WARRANTY * [2]TABLE OF CONTENTS * [3]FIG. 1: PULSE GENERATOR TEST ARRANGEMENT * [4]GENERAL OPERATING INSTRUCTIONS * [5]PERFORMANCE CHECK SHEET __________________________________________________________________ References 1. file:///root/tmp.html#2 2. file:///root/tmp.html#4 3. file:///root/tmp.html#5 4. file:///root/tmp.html#6 5. file:///root/tmp.html#7
