Commands in Alphabetical Order

The following pages give details for each API command. Listed in alphabetical order, each section has a

table that summarizes the main features of the command (C, Visual BASIC, and Delphi language prototypes

and their related parameters). An explanation follows with related information and in some cases a

programming example. Typographic note: Commands, parameters, values, and code use a bold, mono-

spaced

Courier

font to help distinguish characters that can be ambiguous in other fonts.

Used With

All devices

daqAdcArm

allows you to arm an ADC acquisition by enabling the currently defined ADC

configuration for acquisition. ADC acquisition will occur when the trigger event (as specified by

daqAdcSetTrig

)

is satisfied. All ADC acquisition configuration information must be specified

prior to the

daqAdcArm

command. For a previously configured acquisition, the

daqAdcArm

command will use the specified parameters. If no previous configuration was given, or it is

desirable to change any or all acquisition parameters, then those commands relating to the desired

ADC acquisition configuration must be issued prior to calling

daqAdcArm
