Programming the Logic Analyzer
The following example program sets up the logic analyzer to make a simple
timing analyzer measurement.
Example
10
20
30
40
50
60
70
80
90
100
110

The three Xs (XXX) after the "OUTPUT" statements in the previous example
refer to the device address required for programming over either HP-IB or
RS-232-C. Refer to your controller manual and programming language
reference manual for information on initializing the interface.
Program Comments
Line 10 selects the logic analyzer in slot C.
Line 20 names machine (analyzer) 1 "TIMING".
Line 30 specifies machine 1 is a timing analyzer.
Line 40 assigns pods 1 and 2 to machine 1.
Line 50 sets up the Timing Format menu by assigning the label COUNT, and
assigning a polarity and channels to the label.
Line 60 selects the trigger pattern for the timing analyzer.
Line 70 sets the range to 100 ns (10 times s/div).
Line 80 changes the onscreen display to the Timing Waveforms menu.
Line 90 inserts the label "COUNT" in the Timing Waveform menu.
Line 100 specifies the Single run mode.
Line 110 starts data acquisition.
For more information on the specific logic analyzer commands, refer to
chapters 2 through 17.
