12 General Information
The HP E1328A DAC is an "instrument" in the slots of a VXIbus
mainframe. As such, it is assigned an error queue, input and output buffers,
status registers, and is allocated a portion of mainframe memory for reading
storage.
Instruments are based on the logical addresses of the plug-in modules. See
the HP 75000 Series B Installation and Getting Started Guide to set the
addresses to create an instrument.
There are two E1328A DAC functions (see Table 1-1):
Isolated Voltage DACs
Isolated Current DACs

DAC specifications are listed in Appendix A of the HP E1328A Users
Manual. These specificaitions are the performance standards or limits
against which the instrument may be tested.
Description
Output DC voltage up to
10.92 V independently on
each channel. Can use remote voltage sensing with
"no-fault" operation. Connect multiple channels in
series to increase the output to
module. All four channels are independently isolated
and may be floated up to 350 Vdc from ground. Each
channel can be calibrated electronically to 24-hour
specifications.
Output DC current up to
21.8 mA independently on
each channel. Connect multiple channels in parallel
to increase the output to
96 mA for a single module.
All four channels are independently isolated and may
be floated up to 350 Vdc from ground. Each channel
can be calibrated electronically to 24-hour
specifications.
48 Vdc for a single
