STATus subsystem

:STATus:QUEStionable:RF:CONDition?
:STATus:QUEStionable:RF:ENABLe
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 RF questionable status 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will remain set even when the reason for the bits to be set is no longer valid.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 regis-
ters. Condition-type registers reflect the current state of the Willtek 4400. Conse-
quently, 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 229.
– In case, a certain event shall be trapped in a loop within a program, always query
the event-type register.
Example
:STATus:QUEStionable:RF:EVENt?
Value returned: "1".
This means that bit 1 has been set, indicating an RF input overload. If you want to
know whether this RF input overload still persists, read out the related condition-type
register (see command explained below).
Syntax
:STATus:QUEStionable:RF:CONDition?
Parameters
There are no parameters.
Description
This command reads out the current contents of the RF questionable status condition
register. This register reflects the current questionable state of the Willtek 4400
regarding RF and will be updated continuously.
Note: This register is nondestructive. This means that it will keep its contents after
any query.
Query
There is only a query form of this command available. The query will return a string,
containing one integer. The integer will express all bits currently set in the 16 bit RF
questionable status condition register.
Notes
– For further details regarding the basic functions of the STATus subsystem, please
refer to section “Understanding the STATus subsystem” on page 229.
– Bits 4 to 15 (the MSB) of this register are not used. Therefore, the maximum value
returned will be "15"
Example
:STATus:QUEStionable:RF:CONDition?
Value returned: "8".
This means that bit 3 has been set, indicating that the frequency currently received is
out of range of the Willtek 4400 receiver.
Syntax
:STATus:QUEStionable:RF:ENABLe <int1>
Parameters
int1 is an integer. The minimum value for int1 is 0, the maximum value is
32767. The default value is 0.
Description
This command sets the enable filter of the “RF questionable status register group”.
This mask will be ANDed with the RF questionable status event register and thus
decide what kind of events will be forwarded to bit 9 of the “General questionable
status register group”.
