Chapter 2, Methods For Reading Measurement Results

HP BASIC ‘ON TIMEOUT’ Example Program

360

Exit the Measure function and return the result value.

370

The following lines of code handle the case where the request for a measurement
result has timed out.

380

Set up a timeout for any I/O activity on the HP-IB while the control program is
trying to regain control of the Test Set. This will allow the function to gracefully
stop program execution if the control program cannot regain control of the Test
Set. This timeout should only occur if there is some type of hardware failure,
either in the Test Set or the external controller, which prevents them from
communicating via HP-IB.

390

Send a Selected Device Clear (SDC) to the Test Set to put the HP-IB subsystem
into a known state. This allows the control program to regain programmatic
control of the Test Set.

400

Command the Test Set to abort the currently executing measurement cycle. Set
the trigger mode back to repetitive retriggering. Setting the Test Set back to
repetitive retriggering will be implementation dependent.

410

Re-enable event initiated branching. If any event initiated branches were logged
while the Measure function was executing they will be executed when system
priority permits.

420

Exit the Measure function and return a result value of 9.E+99.

430

The following lines of code handle the case where the control program cannot
regain control of the Test Set. The actions taken in this section of the code will be
implementation dependent. For the example case a message is displayed to the
operator and the program is stopped.

440

Display a message to the operator that the control program cannot regain control
of the Test Set.

450

Stop execution of the control program.
