6. Note the nal cen ter frequency setting required to cen ter the video signal.
7. Record the dierence b et w een the initial cen ter frequency setting and the v alue noted in
step 6 in T able 2-2 as frequency error.
8. Repeat steps 5 through 7 for the remaining instrumen t settings in T able 2-2 and T able 2-3
through T able 2-6 as appropriate for eac h instrumen t mo del.
9. Calculate the frequency error as a p ercen t of the sw eep width as follows for eac h of the
results in T able 2-2 and T able 2-3 through T able 2-6 :
frequency error
stop frequency 0 start frequency
x100 = p ercen t
