STATus subsystem
4460 GSM System Option and 4468 EDGE System Option Version 12.20
401
:STAT:OPERation:MEASuring:NTRansition
:STATus:QUEStionable[:EVENt]?
Example :STATus:OPERation:MEASuring:PTRansition 0
This means that none of the positive transitions of the condition-type register will be
forwarded to the event-type register.
Syntax :STAT:OPERation:MEASuring:NTRansition <int1>
Parameters int1
is an integer. The minimum value for
int1
is
0
, the maximum value is
32767
. The default value is
0
.
Description
Sets the NTR mask of the “Measuring operation register group” . This mask will be
AND ed with the up to 16 bits of the NTR filter of the measuring operation condition
register to allow a reset (negative transition) of any bit (i.e. a transition from logic '1'
to '0') to reach the measuring operation
event register.
Note: The default of this mask is 0 – that means that the mask will not allow any
negative transition of the 16 bits of the condition-type register to reach the event-
type register of this group.
Query
There is no query form of this command available.
Example :STATus:OPERation:MEASuring:NTRansition 0
This means that none of the negative transitions of the condition-type register will be
forwarded to the event-type register.
Syntax :STATus:QUEStionable[:EVENt]?
Parameters
There are no parameters.
Description
Reads out the current contents of the general questionable status 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 general questionable status events that have
occurred since the last query of this register. As with any event-type register, the sin-
gle bits will remain set even when the reason for the bits to be set is no longer valid.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. Con-
sequently, condition-type registers will be updated continuously.
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:QUEStionable:EVENt?
Value returned: "
256
".
This means that bit 8 has been set, indicating that the calibration of the Willtek 4400
is out of range. If you want to know whether the Willtek 4400 calibration is still out
of range, read out the related condition-type register (see command explained
below).
