Operating Modes
A3.2.2 FREQUENCY SCANNING
Frequency scanning is started via the command
STS. The scan process is determined by the
following codes (parameters):
f SW (start frequency, stop frequency, step
width)
f DS (digital level threshold (for frequency
scanning, level squelch detection and PZG
line control))
f DWS (dwell time)
f HTS (hold time)
The digital threshold determines the point in
time from which the hold time is added to the
dwell time.
When a running scanning program is inter>
rupted, the receiver automatically operates in
the MANUAL mode (see A3.2.1). The frequency
set last is maintained.
A3.2.3 CHANNEL
In the CHANNEL mode there is a channel set.
In channel operation, as in the MANUAL mode
(see A3.2.1), it is possible to
f alter scanning parameters, hold time and
dwell time
f start a scanning process
f execute special functions and
f execute system functions.
If one of the basic settings (frequency, BFO,
modulation mode, bandwidth, DGC value, type
and time of control) is altered, the receiver
automatically operates in the MANUAL mode
(see A3.2.1).
A3.2.4 CHANNEL SCANNING
CHANNEL SCANNING is started via the com>
mand STQ. Scanning is determined by the
following codes (parameters):
f CS (start channel, stop channel)
f DWQ (dwell time)
f HTQ (hold time)
The digital threshold, which determines the
point in time from which the hold time is
added to the dwell time, is stored in the re>
spective channels.
Cleared (inhibited) channels between the start
and the stop channel are not called up by a
running scan program.
When a running scan program is interrupted,
the receiver automatically operates in the
CHANNEL mode (see A3.2.3). The channel
which has been called up last, remains set.
A3.2.5 CHANNEL SCANNING with
Freely Programmable Chan>
nel List
CHANNEL SCANNING with freely program>
mable channel list is started via the command
STC. Scanning is determined by the following
codes (parameters):
f CH (channel list)
f DWC (dwell time)
f HTC (hold time)
The digital threshold, which determines the
point in time from which the hold time is
added to the dwell time, is stored in the re>
spective channels.
When a running scan program is interrupted,
the receiver automatically operates in the
CHANNEL mode (see A3.2.3). The channel
which has been called up last, remains set.
