Description

The HP E1488A instrument memory module is a
C-size, 1-slot, register-based VXI device. It offers a
convenient way to extend the memory of an instrument
in 2 MB increments (Opt 1B2) up to 16 MB.

Several HP VXI instruments that make use of the local
bus may use the HP E1488A for high-speed data
transfers. Compatible products include: HP E1429B,
HP E1430A, HP E1437A, HP E1431A, E1432A Digitizers,
and HP E1485C Digital Signal Processor. A common
data transfer protocol was designed to ensure data
integrity during high-speed transfers. It implements a
full handshake for each byte of data, even with the
high-speed digitizers. The HP E1488A memory is single
ported, not FIFO. It can either store or send data, but
not both simultaneously.

HP E1488A

The HP E1488A offers a configurable memory size by
mounting the memory chips on plug-in circuit boards.
The memory size can be increased in the field simply by
plugging in additional memory boards and setting the
configuration switches. Multiple memory cards may be
placed in adjacent slots to form a larger memory
system.

Refer to the HP Website for instrument driver
availability and downloading instructions, as well as for
recent product updates, if applicable.

Multiple Memory Modules

If your application requires more memory than a single
module offers, multiple memory cards may be placed in
adjacent slots to form a larger memory system. For
example, if the HP E1429B digitizer is used as a
waveform recorder that requires 32 MB of data storage,
two HP E1488As can be installed in the next two slots.
This gives the HP E1429B a 32 MB memory that takes
data at full speed. If an additional 4 MB are needed,
simply install another HP E1488A in the next slot. The
number of modules is limited only by the number of
slots available in your VXI mainframe.

Battery-backed Static RAM

An on-board battery can be switched in to preserve the
data in case of power failure. By using the internal
battery, the module can even be removed from the
mainframe and still retain its data. For longer data
retention, other standby power sources available are
the VXI +5 V standby line and the faceplate BNC
connector.
