SME SOURce:ERMes
1038.6002.02 3.51 E-133
[:SOURce]:ERMes:STATe:AUTO ON | OFF
The command specifies wether the ERMES data are to be newly calculated on switching from
ERMes:STATe OFF to :STATe ON.
ON The data are newly recalculated and written into list "XMEM"
OFF The existing contents are kept in the memory extension. This can be used to transfer
data generated or changed by an external program to the memory extension and
thus generate a ERMes telegram. *RST value is ON
Example: :SOUR:ERM:STAT:AUTO ON
[:SOURce]:ERMes:CHANnel 0 to 15
The command determines the channel and thus the transmitter frequency for ERMes (cf. Chapter
2, Section "Radiocommunication Service ERMES"). This command also influences the structure
of the ERMES data. This is why the channel cannot be changed by adjusting the frequency using
command SOURce:FREQuency but only using command SOURce:ERMes:CHANnel and then
changing to STATe OFF and then to STATe ON again.
Example: :SOUR:ERM:CHAN 1 *RST value is 0
[:SOURce]:ERMes:ERRor
The SME offers the possibility of entering bit errors into a 30-bit word of the message transmitted
for test purposes. The commands to specify the bit errors and their position are under this node.
[:SOURce]:ERMes:ERRor:MASK 0 to 1073741823
The command specifies the faulty bits of the word of the message selected using ERRor:WORD.
30 bits can be defined as faulty (1) or perfect (0). The decimal number transmitted is converted
internally into a 30-bit binary number and thus determines the 30 bits. These bits are XORed with
the word to be corrupted and hence determine which bits of this word are transmitted correctly or
wrongly. *RST value is 0
Example: :SOUR:ERM:ERR:MASK 5
[:SOURce]:ERMes:ERRor:BATCh A to P
The command specifies in which of batches A to P the faulty word is. The faulty word is
determined by command SOURce:ERMes:ERRor:WORD. *RST does not influence this setting.
Example: :SOUR:ERM:ERR:BATC P
[:SOURce]:ERMes:ERRor:WORD 0 to 153 (0 to 189 for long batch)
The command determines the faulty word in the batch selected by means of command
SOURce:ERMes:ERRor:BATC. *RST value is 0
Example: :SOUR:ERM:ERR:WORD 111
[:SOURce]:ERMes:MESSage
The commands to set the destination address and to determine the message data are under this
node.
