4·3 0. HP·IB Check (Optional)
Up to this point the 3585A has been checked only as a bench operated instrument. If the in­
strument is to be used with a controller, the HP-IB interface should be checked. The pro­
gram shown in Figure 4-7 will check the HP-IB operation of the instrument to a high level of
confidence. This program is flow charted using controller independent language so that it
may be adapted to your controller. If you have a -hp- 9825A calculator, a listing of this pro­
gram appears in Table 4-3 . the program is also contained on File 26, Track
Automatic Performance Test tape (P.N. 03585-1000 1 ). If an error is detected in the HP-IB
interface of the 3585A, an error number will be printed out. The error definitions are con­
tained in Table 4-2 and may be used to help locate problems on the 3585A HP-IB board.

mance Test tape in the calculator tape slot and press the following keys:
