State Storage
State Storage
The 3499A/B/C provides the capability to store setups, and then recall
them to put the instrument back into a known configuration.
Information that can be stored includes:
•
Status of all relay channels (open or closed)
•
Status of digital I/O ports (input or output, flow control, etc.)
•
Remote interface settings (address, baud, etc.)
Additionally, you can include a stored state in a scan list as a channel.
Firmware Revision Differences
State storage behavior differs depending upon the firmware revision of
your 3499A/B/C (see page 55).
•
Firmware revision 1.0 must be upgraded. Please contact your nearest
Agilent Technologies Office for details.
•
Firmware revisions 2.0 and 3.0 allow up to 10 states to be stored.
Firmware revision 4.0 allows up to 40 stored states.
•
Stored states are lost if power is removed for firware revisions 2.0 or
3.0. Stored states are preserved when power is removed for firmware
revision 4.0.
•
Storage memory locations are numbered 01 to 10 for Firmware
revision 2.0 and 3.0. Memory locations are number 01 to 40 for
Firmware revision 4.0.
•
Before recalling a stored setup, the instrument verifies that all
module types and slot assignment match the setup. If a mismatch is
detected, an error ("RECALL FAILED") will occur.
