Other Subsystems
In addition to the major functions (sub
-
systems), there are several other subsys
-
tems in the instrument model.
The different blocks have the following
functions.
n
CALibration
This subsystem controls the calibration of
the interpolators used to increase the res
-
olution of the CNT-8X counters.
n
DISPlay
Commands in this subsystem control
what data is to be present on the display
and whether the display is on or off.
n
FORMat
The FORMat block converts the internal
data representation to the data transferred
over the external GPIB interface. Com-
mands in this block control the data type
to be sent over the external interface.
n
MEMory
The MEMory block holds macro and in
-
strument state data inside the counter.
n
OUTPut
This subsystem controls the analog out
-
put available in the CNT-8X counters.
n
STATus
This subsystem can be used to get infor
-
mation about what is happening in the in
-
strument at the moment.
n
Synchronization
This subsystem can be used to synchro
-
nize the measurements with the control
-
ler.
n
SYSTem
This subsystem controls some system pa
-
rameters like timeout.
n
TEST
This subsystem tests the hardware and
software of the counter and reports errors.
n
TRIGger
The trigger block provides the counter
with synchronization capability with ex-
ternal events. Commands in this block
control the trigger and arming functions
of the Timer/ Counter.
Order of Execution
All commands in CNT-8X counters are se-
quential, i.e., they are executed in the same
order as they are received.
If a new measurement command is re
-
ceived when a measurement is already in
progress, the measurement in progress will
be aborted unless WAI is used before the
command.
