3.6.11.14 SOURce:POCSag Subsystem
POCSAG is a standard which in its various implementations (e.g. CITYRUF, SCALL) allows convenient
paging. When equipped with the SME-B42 (POCSAG), SME-B11 (DM coder) and SME B12 (DM
memory extension) options, the SME generates call signals complying to the POCSAG standard. All
essential parameters and the message to be transmitted are freely selectable.

[:SOURce]:POCSag:STATe ON| OFF
The command switches all of the other active DM modulation settings off. In contrast to ERMES,
the RF frequency is not changed. Each time OFF is switched to ON, the data for the memory
expansion are recalculated and written into the "XMEM" list. The data must be recalculated
whenever any POCSAG parameter other than POCSag:DEViation is changed. This means that
STATe OFF should be briefly activated after every change.
Example: :SOUR:POCS:STAT ON *RST value is OFF
[:SOURce]:POCSag:MODulation FSK | FFSK
The command selects the desired modulation.
Two types are available for POCSAG, FSK und FFSK.
FSK The RF is directly modulated with the data signal.
FFSK An LF is first modulated, which is then used as the modulation signal for the RF.
Example: :SOUR:POCS:MOD FSK *RST value is FSK
