‘Device Clear’
Either of the commands DCL or SDC will force the following instrument states:
•
all IEEE 488 input and output buffers cleared;
•
with 'IFC' (Interface Clear), any device-dependent message bus holdoffs cleared.
•
the status byte is changed by clearing the MAV bit.
These commands will not:
•
change any settings or stored data within the device except as listed above;
•
interrupt analog output;
•
interrupt or affect any functions of the device not associated with the IEEE 488
system;
6.4.2.5
Levels of Reset
Three levels of reset are defined for IEEE 488.2 application programs, a complete system
reset being accomplished by resetting at all three levels, in order, to every device. In other
circumstances they may be used individually or in combination:
IFC
Bus initialization;
DCL Message exchange initialization;
∗
RST Device initialization.
The effects of the
∗
RST command are described in Appendix C to this section.
