Special Functions
A3.7.16 Master / Slave Operation
Command syntax:
Code: MS
Parameter: .................... a
Possible entries
Range: .......................... 0 to 99
Note:
The command block generated via command
MS<parameter> contains all basic receiver
settings, consisting of frequency, BFO fre>
quency, modulation mode, DGC value, band>
width, type and time of control as well as the
currently effective difference between receive
frequency and IF passband curve.
Example:
Transfer of the currently effective receiver set>
ting from the receiver with the master address
03 to a receiver with the slave address 04
Command = rA03MS04?
In the receiver with the address 03 a command
block with the format
rA04F6000000I5R2DT1W1B800D45PB>100?
is generated.
The command block contains the following in>
formation:
f Slave address: A04 = 4
f Frequency: F6000000 = 6 MHz
f Modulation mode: I5 = CW
f Control type: R2 = AGC+DGC
f Control time: DT1 = 150 ms
f Bandwidth: W1 = 150 Hz
f BFO frequency: B800 = 800 Hz
f DGC value: D45 = 45 dBoV
EMF
f Passband tuning: PB>100 = >100 Hz
A3.7.17 Inquiry of Frequency
Deviation and / or Offset
Command syntax:
Code: DF
Reply
Parameter: .................... a, b
Possible values for a> (lower frequency) and
b>parameters (upper frequency)
Range: ........................... >1200 to 1200
Resolution: .................... 1 Hz
Freq. deviation (Hz): ...... (b > a)
Freq. offset (Hz): ............ (b+a)∏2
Note:
Via this command the frequency deviation
(only in modulation modes FSK and AFSK) as
well as the frequency offset (not in modulation
modes USB, LSB and ISB) can be determined.
Example 1:
Determining the currently effective frequency
deviation and offset
Command = rDF??
Æ Reply = rDF>210,210?
The frequency deviation is 420 Hz, and the fre>
quency offset is 0.
Example 2:
Determining the currently effective frequency
deviation and offset
Command = rDF??
Æ Reply = rDF1000,1040?
The frequency deviation is 40 Hz, and the fre>
quency offset is 1020 Hz. Thus the set receive
frequency is to be reduced by 1020 Hz.
Example 3:
Determining currently effective frequency off>
set
Command = rDF??
Æ Reply = rDF>900,>900?
The frequency offset is >900 Hz. Thus the set re>
ceive frequency is to be increased by 900 Hz.
