For programmed scan:
Program scan edge frequencies into scan edge mem-
ory channels P1 and P2.

ory channels P1 and P2.
For
∂
F scan:
Set the
∂
F span (
∂
F scan range) in the scan screen.
For memory scan:
Program 2 or more memory channels except scan
edge memory channels.
Program 2 or more memory channels except scan
edge memory channels.
For select memory scan:
Designate 2 or more memory channels as select mem-
ory channels. To designate the channel as a select
memory channel, choose a memory channel, then
push [(F-3)SELECT] in the scan screen (memory
mode) or in the memory channel screen.

• The scan function can be used on the main readout only.
• You can operate a scan while operating on a frequency using
the dualwatch or split functions. See p. 31 for details.
PROGRAMMED SCAN
Repeatedly scans between two scan edge frequencies
(scan edge memory channels P1 and P2).
