NOTES:
(1) When operating as a Phase Shifter outside the Main Band Frequency Range, a TTL Low (0) applied to the J3 Power/Control Connector Freq. Correction Pin (pin 3) will result in Stretch Band Frequencies exhibiting enhanced performance characteristics. The resultant Insertion Loss, Accuracy and PM/AM specifications will be the same as those shown for the Main Band Frequency Range. When using the unit as a Frequency Translator, similar enhanced performance can be achieved for Carrier & Sideband Suppression.
(2) All specifications are met using five or more most significant bits for 0 to 200 kHz translation rates. For 201-500 kHz translation rates, only the four most significant bits are used.
