3.6.11.4 SOURce:ERMes Subsystem
This subsystem contains the commands to set the ERMES signal. ERMES uses a 4FSK modulation.
The parameters of the DM:FSK4 subsystem, however, are not influenced by settings in the ERMes
subsystem. Switchover between the output of useful or filler subsequences is by means of the
TRIGger:DM subsystem.

[:SOURce]:ERMes:STATe ON | OFF
The command switches on the ERMES signal and hence switches off all other active DM
modulations. The RF frequency is set to the value determined by command
SOURce:ERMes:CHANnel.
If STATe:AUTO is ON with every change from OFF to ON, the data for the memory extension are
recalculated and written into list "XMEM". Every change of one of the ERMES parameters
requires the data to be recalculated, i.e. a brief switchover to STATe OFF after every change.
Example: :SOUR:ERM:STAT ON *RST value is OFF
