IEEE-488 Option -05 7

Performance Testing

7-10. Installing the IEEE-488 Option

1.Place the IEEE-488 PCA into position so that the edge of the pca fits in the chassis guide. Then line up connecting pins with the matching connector on the Main PCA, and slide the pca into position.

2.Install the single 6-32, 1/4-inch panhead Phillips head screw in the corner of the IEEE-488 PCA.

3.If necessary, attach the rear panel connector using 7 mm nut driver.

4.At the pca, attach the ribbon cable leading from the rear panel connector.

7-11. Performance Testing

Use the following performance test program to verify operation of the IEEE-488 Interface. This program is written for use with the Fluke 1722A Instrument Controller and its interpreted BASIC language. The program may be adapted to the language of any IEEE-488 controller.

This performance test communicates to an instrument that has been configured for IEEE- 488 operation at address 0. Lines 170 and 180 initialize the IEEE-488 bus and send a selective device clear to the instrument. A multiple byte command is sent to the instrument (by line 190) to clear the instrument status. Another command sequence (including a query) is sent to the instrument by line 210; the instrument asserts Service Request (SRQ) to signal that a response is available. Lines 530 through 560 first poll the instrument for status, then input the response from the instrument. Lines 230 through 270 test for proper operation and print the results.
