scan list
a list of channels supplied to NI-SWITCH that indicates the order in which
channels will be scanned
SCANADVD
scanner advance signal—in handshake scanning this signal is generated by
the switching module to let the instrument or DMM know that the
switching module has finished settling at the current channel
scanner advanced
trigger
the trigger generated by the switch card when scanning. The trigger occurs
after the switch card has closed a switch and the switch has settled.
SCXI
Signal Conditioning eXtensions for Instrumentation—the National
Instruments product line for conditioning low-level signals within an
external chassis near sensors so only high-level signals are sent to
DAQ devices in the noisy PC environment
soft front panel
a graphical program included with NI-SWITCH that you can use to
interactively control the switch
T
terminal block
an accessory containing wire connection points, typically screw terminals
trigger
any event that causes or starts some form of data capture
V
V
volts
VDC
volts, direct current
VMC
voltmeter complete signal—during synchronous or handshake scanning
with an external DMM this signal advances the switching module to the
