Frequency Scanning
A3.4.8 Programming Example
Example:
The unaddressed VLF>HF receiver is to be set to the following frequency scanning parameters:
f Start frequency: 6 MHz
f Stop frequency: 6.5 MHz
f Step width: 5 kHz
SW6000000,6500000,5000
f Dwell time: 100 ms = DWS100
f Hold time: automatic stop of scanning = HTSf
f Digital level threshold: 60 dBoV
EMF
= DS60
f Control type: AGC = R0
f Control time: 25 ms = DT0
Subsequently scanning is to be started (= STS) and the operating status (= M) is to be inquired.
Command: rSW6000000,6500000,5000DWS100HTSfDS60R0DT0STS

The receiver is in the operating mode FREQUENCY SCANNING.
As a result of the programmed scanning process the receive frequency changes, starting at 6 MHz,
in increments of 5 kHz until the receive frequency of 6.5 MHz is reached. The receiver remains on
each new frequency for 100 ms. If the currently effective receive level exceeds the digital thre>
shold of 60 dBoV
EMF
, scanning is automatically stopped Æ operating mode MANUAL.
A stopped scanning process can be resumed via the command CO.
