Model 6485 Picoammeter Instruction Manual
H. Although there is not a 'Busy' event in the Model 6485 Status Model, there is an
Operation Complete event (the compliment of 'Busy'). This example refers to the
use of the Operation Complete SRQ (rather than 'Busy').
I. The DDC errors do not map one-to-one mapping with SCPI errors. There are two
SCPI errors that cover all of the 6485 Error Events (EE). This will be fairly equiv-
alent to using the M39 DDC command. After getting an SRQ on an Error Event, to
clear the event, read the Standard Event Register (*ESR?, then talk the instrument).
There may also be an Error Available event set in the status byte (serial poll).
NDS: Not Directly Supported in Model 6485.
NEW: Commands added to 6485 that were not available in the 485 command set.
