A3.2 Operating Modes
The receiver can be operated in the following
five operating modes:
f MANUAL
f FREQUENCY SCANNING
f CHANNEL
f CHANNEL SCANNING
f CHANNEL SCANNING with freely program>
mable channel list
A3.2.1 MANUAL
In the MANUAL mode no channel is set.
For the basic settings of the VLF>HF receiver the
following codes are possible:
f F (frequency)
f B (BFO frequency)
f W (bandwidth)
f Q (quasi>continuous bandwidth, R&S
EK!896 and R&S EK 895 with option R&S
EK 895S7)
f I (modulation mode)
f R (control type)
f DT (control time)
f D (DGC value)
In the MANUAL mode the following scanning
parameters can be altered:
f SW (see A3.2.2),
f CS (see A3.2.4) and
f CH (see A3.2.5) as well as
f DS (digital level threshold (for frequency
scanning, level squelch detection and PZG
line control)),
f DWC, DWQ, DWS (dwell time) and
f HTC, HTQ, HTS (hold time)
At the same time one of the following scan>
ning processes can be started:
f Frequency scanning (STS, see A3.2.2)
f Channel scanning (STQ, see A3.2.4)
f Channel scanning with freely program>
mable channel list (STC, see A3.2.5)
The possible special functions are characterized
by the following codes:
f PB (passband tuning)
f L (receive level)
f PL (level control for PZG line)
f PS (syllabic control for PZG line)
f P (PZG line status)
f C (CM status)
f BI (BIT status)
f ST (storage into channel)
f K, CL, RS (editing of channel contents)
f MS (master / slave operation)
f DF (frequency deviation and / or offset)
f NB (noise blanker)
f NF (notch filter)
f SQ (squelch)
f SQT (squelch type)
f PA (preamplifier)
f DEF (default setting)
f SE (switching digital selection on or off,
with R&S FK 896D only)
f DS (digital level threshold (for frequency
scanning, level squelch detection and PZG
line control))
f SST (syllabic squelch threshold (for syllabic
squelch detection and PZG line control))
f SSBM (USB Rx filter mode)
The possible system functions are characterized
by the following codes:
f A (address)
f V (software version)
f FIB (IF filter)
f OP (options)
f SA (signal BYPASS)
f IF (IF signal)
f M (operating status)
f CO (scanning status)
f ERR (error status)
f RESET (software reset)
f REM (local control)
f IDENT (software type and ident. no.)
f VER (software version and DSP version)
Via the command Ks<parameter> a channel
can be called up, and the receiver is auto>
matically in the CHANNEL mode (see A3.2.3).
