4460 GSM System Option and 4468 EDGE System Option Version 12.20
:STATus:OPERation:SIGNalling:GSM[:EVENt]?
Description
Sets the PTR mask of the “General operation register group” . This mask will be AND ed
with the up to 15 bits of the PTR transition filter of the general operation condition
register to allow a positive transition of any bit (i.e. a transition from logic '0' to '1')
to reach the general operation
event register.
Notes
– The default of this mask is 32767 – that means that the mask will allow any pos-
itive transition of the lower 15 bits of the condition-type register to reach the
event-type register.
– Bit 16 of the general operation condition register is not used.
Query
There is no query form of this command available.
Example :STATus:OPERation:PTRansition 0
This means that none of the positive transitions of the condition-type register will be
forwarded to the event-type register.
Syntax :STATus:OPERation:SIGNalling:GSM[:EVENt]?
Parameters
There are no parameters.
Description
Reads out the current contents of the signaling operation event register.
Note: Event-type registers are read-only and self-destructive. They will be cleared
after any query.
Query
There is only a query form of this command available. The query will return a string,
containing one integer.
The value returned represents all signaling operation events that have occurred since
the last query of this register. As with any event-type register, the single bits will
remain set even when the reason for the bits to be set is no longer valid. Please note
that this is the main difference between event-type and condition-type registers.
Condition-type registers reflect the current state of the Willtek 4400. Consequently,
condition-type registers will be updated continuously.
The bits of the signaling operation event register have the following meaning:
Bit 0 (decimal 1): The 4400 is in idle mode
Bit 1 (decimal 2): The 4400 is paging the mobile.
Bit 2 (decimal 4): A call has been established and is currently active.
Bit 3 (decimal 8): The BER loop has been closed.
Bit 4 (decimal 16): Async mode (e.g. Generator/Analyzer) active.
Bit 5 (decimal 32): The 4400 is calling the mobile under test. A BS call is in progress.
Bit 6 (decimal 64): Not used (reserved).
Bit 7 (decimal 128): Not used (reserved).
Bit 8 (decimal 256): Alerting.
Bits 9 through 15: Not used (reserved).
Notes
– For further details regarding the basic functions of the STATus subsystem, please
refer to section
“Understanding the STATus subsystem” on page 345 .
– In case, a certain event shall be trapped in a loop within a program, always query
the event-type register.
Example :STATus:OPERation:SIGNalling:GSM:EVENt?
Value returned: "
8
".
This means that bit 3 of the signaling operation event register (stands for BER loop
being closed) has been set.
