　　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.
