age1439_status_get
Reads status register information for the module.
VXIplug&play Syntax
ViStatus age1439_status_get(ViSession id, ViPInt16 statusPtr);
Parameters
id
is the VXI instrument session pointer returned by the age1439_init function.
statusPtr
points to the status word. The bits are defined below:

Description
These two bits indicate the current state of the
measurement loop. See
"The measurement loop" in
and
"age1439_meas_status_get" on page 156

for more information about these states
Passed: This bit is always set to 1
This bit is set when the module is ready after power-on. See
the VXIbus Specifications for more information.
This bit is set internally whenever any data has been written
to the receive FIFO, or read from the transmit FIFO of the
fiber interface within the past 500 milliseconds,
approximately. The bit is cleared automatically when activity
ceases on the fiber interface
This bit is set internally whenever an error condition occurs
on the fiber interface. Reading the status register does not
clear this bit. To do this, the
age1439_fiber_error_clear
function must be used explicitly. The function
fiber_error_get
can be used to read the contents of the fiber
error register. If the error is continuously present, the bit will
not be cleared.
Setup error: An invalid parameter value was requested. If an
invalid block size was requested, the closest valid block size
is used until a change to an interrelated parameter makes the
requested block size valid. If a data resolution, data type,
filter bandwidth, trigger delay, or filter decimation parameter
was requested which would result in an inability to make a
measurement, the previous valid parameter is used until a
change to an interrelated parameter makes the requested
parameter valid
Sync/Idle Complete: This bit is set when the most recent
user-initiated Sync or Idle change has propagated through to
all modules in a system. The change is a result of asserting
Sync or forcing Idle via the Control Register or issuing a
meas_control command or function
