plitude of 5 cm. This must be repeated for each Signal Gen­
erator frequency change.
(4) Check the display flatness over the dispersion window
by tuning the signal across the graticule area (from the
left to right side) with the RF CENTER FREQ control. Signal
amplitude should not change more than ± 1 .5 d B from its
average amplitude, or a total of 3 dB.
It is possible that the 5 cm signal reference am ­
plitude established in step ( 3 ) may be a minimum
