Making Measurements

The benefit of non- sequential commands is that, in some situations, they can reduce the overall execution times of programs. For example, you can set the peak excursion, peak threshold, and elevation and use a *WAI command at the end to save time. However, non- sequential commands can also be a source of annoying errors. Always use the *OPC query or *WAI command with the non- sequential commands to ensure that your programs execute properly.

For example, suppose that you wanted to set the elevation correction value and then send an :INIT:IMM command. The following program- ming fragment results in an error “–213 Init ignored”. This occurs because the :ELEVation command causes the recalculation of the data which is like sending the :INIT:IMM command. When the actual :INIT:IMM is sent, the error occurs because the command is already in progress.

OUTPUT 720;”:INIT:IMM”

OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”

OUTPUT 720;”:INIT:IMM”

Use an *OPC? query to ensure that the :ELEVation command has com- pleted as shown in the following lines:

OUTPUT 720;”:INIT:IMM”

OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”

OUTPUT 720;”*OPC?”

ENTER 720;Response$

OUTPUT 720;”:INIT:IMM”

Or, the *WAI command could be used:

OUTPUT 720;”:INIT:IMM”

OUTPUT 720;”:SENSe:CORRection:ELEVation 1000”

OUTPUT 720;”*WAI?”

OUTPUT 720;”:INIT:IMM”
