2 . Connect the Signal
Generator RF out connector to the 50
ohm inputof the
frequency counter . Set the counter to read
frequency to seven
digits .
3 . Observe the
frequencycounter reading .

Increase the
setting
of
the
Signal Generator FREQUENCY selector in
1
kHz
steps and verify that the
frequencycounter reading increases
by 1 .00 kHz ±1 count for each step
increasefrom 1 through
9

Repeat the
procedure in step 3 for all other step in-
creases indicated in
the table belowbeginningwith the 10
kHz digits .
If
the
actual counterfrequency increase per
step is equal to the allowable
increase per step ±1 count
for each of the
steps indicated in the table, place a check
mark in the applicable
space on line 1 of the PTR .
