Service pulse commands have reserved names and typically used for
internal purposes of spectrometer. Pulse engine treated them in a
special way. The syntax of pulse commands definitions is the same
with ordinary commands. Defining of service pulse commands is not
obligatory. Including of the definitions into configuration file
causing pulse engine to incorporate corresponding action into full
pulse sequence. Using of service pulse command in the pulse
program (except detect) is not welcomed.
Full pulse sequence consists of pulse sequence produced from PPL
and number of service sequences produced by service pulse commands
(see Fig.1). Pulse, reptime and eos sequences are repeated according
to amount of repetitions specified. Eor sequence finishing the full
sequence.

Description
|
|
scope
|
Scope trigger. Generate trigger synchronously with the chosen
pulse of the pulse sequence.. All channels of this command have to be of up
or down type. Length have to be specified.
Part of sequence.
|
|
detect
|
Acquisition trigger. All channels of this command have to be
of up or down type. Length have to be
specified. Part of sequence.
|
|
reptime
|
Command to be executed to specify sequence repetition time.
See also reptype key in CFP
file overview. Channels can be of arbitrary type. If no
pulses needed channel type 'space' have to be specified. The
length of pulse is calculated as a difference between repetition
time and lengths of pulse sequence and eos sequence.
|
|
bos
|
Begin of sequence command. Appears before the sequence. All
channels of this command have to be of up, down
or space type. Length have to be specified.
|
|
eos
|
End of sequence command. Depending on the eos key
(see Pulse Configuration) can appear
before or after reptime pulse. All channels
of this command have to be of up, down
or space type. Length have to be specified.
|
|
eor
|
End of run command. Appears after all repetitions are done and
finishing a full pulse sequence. All channels of this command
have to be of up or down type.
