keys. Frequencies in the manual sweep mode are
synthesized, just as they are in CW mode.
There are two major differences between manual sweep and a sweep
generated by activating the CW function and rotating the rotary
knob or pressing the ARROW keys.
1. The sweep output voltage ramp is 0 to
+lO
V in both modes,
but in CW mode, OV corresponds to lowest frequency of the
synthesizer frequency range and
+lO
V corresponds to the highest
frequency of the range. In manual sweep mode, OV corresponds
to the start frequency specified and
+lO
V corresponds to the
stop frequency specified. In both cases, the sweep voltage at
intermediate frequencies is a linear interpolation of the frequency
span. For example, a frequency half-way between the start/stop
limits has a sweep voltage of
5V.
2. The bandcross points in CW mode occur at 2.4, 7, 13.5, 20, 25.5,
and 32 GHz. In manual sweep mode the bandcrossing points
have 200 MHz of flexibility, that is automatically used by the
synthesizer for optimum performance. For example, a 2.3 to 7.1
GHz sweep could be accomplished without any band changes in
manual sweep mode.
