Programming Examples
Analyzer System Setup Examples
• The elements from each calibration array are read in.
• The next calibration array is requested until all the arrays have been read.
• The calibration type is sent to the analyzer.
• Each calibration array is sent.
• The calibration is activated.
• The analyzer is released from remote control and the program ends.
Running the Program
Before executing the program, perform a calibration.
The program is able to detect which type of calibration is active. With that information, it
predicts how many arrays to read out. When all the arrays have been sent to the computer,
the program prompts the user. The operator then turns the calibration off or performs a
completely different calibration on the analyzer and continues the program. The computer
reloads the old calibration. The operator should not preset the analyzer because the
instrument settings must be the same as those that were present when the calibration was
taken.
NOTE The retransmitted calibration is associated with the current instrument
state: the instrument has no way of knowing the original state associated
with the calibration data. For this reason, it is recommended that the learn
string be used to store the instrument state whenever calibration data is
stored. The next example demonstrates how to reload the analyzer state with
both the learn string and the calibration arrays.
BASIC Program Listing
10 ! This program shows how to manipulate calibration data from the analyzer.
20 ! It demonstrates how to read calibration data from the analyzer, and
30 ! how to replace it. The type of calibration active is determined and
40 ! the program reads in the correct number of arrays. The number of points
50 ! in the trace, and in the cal array, is determined and used to dimension
60 ! storage arrays.
