Appendix A SCPI Command Reference
STATus subsystem
276 WCDMA Options Version 6.20
:STATus:OPERation:CONDition?
:STATus:OPERation: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 general 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remain set even when the reason for the bits to be set is no longer valid.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.
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:OPERation:EVENt?
Value returned: "32".
This means that bit 5 (the 'waiting for a trigger' bit) has been set. This indicates that
a 'waiting for a trigger' event did occur. If you want to know whether the Willtek
4400 is still waiting for the trigger to occur, read out the related condition-type reg-
ister (see command explained below).
Syntax
:STATus:OPERation:CONDition?
Parameters
There are no parameters.
Description
This command reads out the current contents of the General Operation Condition
Register. This register reflects the current operational state of the Willtek 4400 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 gen-
eral operation 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.
– Bit 15 (the MSB) of this register is not used. Therefore, the maximum value
returned will be "32767".
Example
:STATus:OPERation:CONDition?
Value returned: "512".
This means that bit 9 (the MEASure summary bit) has been set, indicating that some
measurement is currently in progress. Bit 9 will be reset as soon as the measurement
has been completed.
Syntax
:STATus:OPERation:ENABLe <int1>
Parameters
int1 is an integer. The minimum value for int1 is 0, the maximum value is
32767. The default value is 0.
