Additional Configurations
This section contains information on two additional configurations for the
multimeter:
• selecting VME RAM, and
• disabling front-panel for stand-alone applications.
Selecting VME RAM Up to 12 Mbytes of VME RAM can be added to the B-size mainframe to
be used for multimeter reading storage. The following lists guidelines for
using VME RAM with the multimeter:
• Dynamic RAM must handle its own refresh, and not require any
command module activity.
• VME cards can never be a bus master.
– B-size mainframe does not have bus arbitration.
• VME cards must exclude the first and last 2 Mbytes of A24 space.
– B-size mainframe’s system ROM is located in the lower
2 Mbytes.
– B-size mainframe’s system RAM is located in the upper
2 Mbytes.
• VME RAM may not be used for IBASIC program memory.
The following lists guidelines in selecting a VME card:
A24 A24 address space
D16 16 bits of data at a time
3U A size slot
6U B size slot
Disabling
Front-panel for
Stand-alone
Applications
When using the HP E1326B Multimeter as a stand-alone instrument, the
HP E1301A front-panel keyboard can be disabled without disabling the
display. To disable the front-panel keyboard, use the following guidelines:
– send a "REMOTE" command to each instrument, and
– send a "LOCAL LOCKOUT" to the HP-IB interface.
This should allow the display to still work, but disable the keyboard and the
softkeys.
