if the start frequency is greater than the stop freque nc y, the HP 8340A will change the start
or stop frequency to achieve the required separation. The order in which start/stop is

either of the start/stop keys and then either of the CF/ .6.F keys) the sweep limits are the
same. The start frequency appears in the left FREQUENCY MHz display.
