1 i
Perform the preliminary
procedures in paragraph
3-34. Set the 5345A
POWER switch to ON.
The 5355A key LEDs illuminate momentarily, key illuminates. 5345A
displays head code momentarily. (See paragraph 3-56,} 5345A displays ail zeros.
2 Press I *
Key LED illuminates. 5345A displays -1. GHz.
NOTE
Steps 3 through 9 show how to expand the number of digits in the
display, position the decimal point and select displayed resolution for ;
precise offset frequencies, if these procedures are understood, proceed
to step 10.
