Center Frequency Readout
The 1705A is equipped with alphanumeric readout for the CENTER FREQUEN-
CY. This readout works in conjunction with a cursor. In FULL SPAN/DIV, the
cursor is actually a bright-up zone on the trace. See Figure 2-7. Actual position
of the readout on the crt can be positioned to a location where it will not interfere
with the measurements being made.
