Output Protection : Shall meet for 5 minutes for all VSWR'S (around the Smith Chart) of 20:1 without damage. |
2. |
Output stability of all VSWR'S (around the Smith Chart) of up to 5:1 under continuous operation of a duty cycle of 5 minutes transmitting, and 1 minute receiving. |
3. |
Reverse Polarity Protection : Shall have reverse polarity protection and be operable with positive and negative grounding. |
4. |
Standard Operating Temperature : -30ºC +50ºC |
5. |
Storage Temperature : -140ºC +70ºC |
6. |
Electrostatic Discharge Protection : All external case and component parts shall withstand the application of 15 kV ESD without causing failure or malfunction to the unit. |
Test Conditions - Probe : 150 pF with 500 ohm in series Temp. : 25ºC
Note: Nominal specs represent the design specs; all units should be able to approximate these, some will exceed and some may drop slightly below these specs. Limit specs represent the absolute worst condition that still might be considered acceptable; in no case should a unit perform to less than any limit spec.
