Module Description
The HP E1313/E1413 is a 64-channel high-speed scanning Analog-to-Digital
Converter with optional per-channel signal conditioning in a single width
VXIbus module. It scans up to 100,000 channels per second, while
autoranging and converting the readings into Engineering Units (EU). The
reading stream is routed to a 65,024 reading FIFO buffer, while the latest
reading from each of the 64 channels can be quickly accessed from a Current
Value Table (CVT). All readings are returned to the FIFO and CVT in IEEE
754, 32-bit floating point format either with EU conversion or as input voltage.
Channel selection is controlled by four scan lists which can contain up to
1,024 channel assignments each. Another list called the “ List of Lists” can
reference each of the scan lists (1 through 4) up to 1,024 times. The HP E1313/
E1413 also provides on-board calibration sources to allow on-line, single
command, all-channel calibration. The module can also compensate for system
wiring offsets. The HP E1313/E1413 can accept any mix of up to eight Signal
Conditioning Plug-ons (SCPs). All of these features can be accessed with the
SCPI and Compiled SCPI instrument languages. The following sections
describe step-by-step how to program the module.
