Figure 2-5: Relationship of sweep to graticule showing minimum and maximum
frequencies when CENTER FREQUENCY is set to mid band
Figure 2-6 shows frequencies associated with the graticule lines in FULL
SPAN/DIV when the CENTER FREQUENCY control is set to 1400 (for
L--Band) or 70 MHz (for the 70 MHz). Note also that the HORIZONTAL
POSITION control affects the frequency-to-graticule scale resolution. Determin-
ing where the HORIZONTAL P OSITION control is set can easily be determined
using one of the magnified SPAN/DIV settings and the readout cursor.
