RAM

Random Access Memory.

register-based VXI device

Register-based devices communicate with the VXI Bus by way of registers. They must be programmed with low-level binary commands but they can communicate faster than message-based devices. The HP E1432A and HP E1433A are register-based VXI devices.

registers

Memory locations in the hardware of a VXI module which can be used to program the module at a low level.

RPM

SCA

Signal Conditioning Assembly. An example is the 4-channel input assemblies used in the HP E1432A (also called Vibrato).

sample rate

The rate at which the measurement data is sampled. For the HP E1432A, the sample rate is 2.56 times the frequency span. Sample rate is abbreviated “Fs” (for “sample Frequency”).

settling

When settling, the digital filter waits a designated number samples before outputting any data.

SFP

see Soft Front Panel

shared memory

Memory locations in both a VXI module and in a host or controller which are shared and can be used to transmit data between the host and module.
