Line No.
10 to 170
Same as in Example 1 except for declaration of Esr_byte.
190 to 240
The new Wait_to_settle subroutine.
200
Start REPEAT loop.
210
Send the *ESR? command to the switch. This queries the
switch for the Event Status Register value.
220
Read the value of the Event Status Register.
230
If the LSB of the ESR is 1 (that is, the switch is settled),
exit the loop. If the LSB is 0 (that is, switch is moving),
then loop back to line 200.
240
Return from subroutine.
Example 4: Input/output multiplexers
This program illustrates how two Agilent 86060C-series switches may be used
to function as input and output multiplexers in an automated test system. For
this example, two 1 × 8 switches are used to test 8 optical devices under test.
The block diagram for this test system is shown below.
