Keithley 2002 User Manual

HP3458A Emulation Mode
H-3
Unsupported queries
If an unsupported query is detected, a -1 will be returned as
the query response in most cases. These are queries support-
ed by the HP3458A but not supported by the Model 2002.
FIXED2 and EXTOUT will not return -1, however.
Sending the query form of commands not supported by the
HP3458A will result in an error.
Query format
The query format (set by the QFORMAT command) will
always be set to NUM.
Error checking
The following commands pertain to HP3458A emulation
mode error checking:
EERR ON|OFF Enable/disable emulation mode error
checking.
EERR? Query current state of emulation mode
error checking.
If EERR is ON, an error message will appear on the front
panel, as well as in the error queue, and bit 14 in the error
register will be set when an error occurs. To generate an SRQ
when an emulation mode error is detected, set EMASK to
16384 and RQS to 32.
