SYNTAX
DESCRIPTION
MNEMONIC
TRI,s,a/n1,C1/n2,C2/.../n20,C20
TRIgger sequence
TRI,+,1
s
The direction of displacement : + or -
a
The absolute position of the start (1st
trigger): -231 to 231-1.
ni
The number of integration intervals of the
"i" subsequence (ni = 1 to 65535 or ni=*;
the sign “*” stands for “infinity”).
Ci
The number of events received before the
sending of a trigger to the integrator. The
integration intervals of the "i" sub-
sequence is given in number of input
events (1 to 4095).
The maximum number of sub-sequences
is 20.
Default
Note:
An integration interval is defined by two
consecutive trigger signals. The second
signal also starts the next interval,
meaning that there is no dead time
between each integration interval.
TRI,?
Returns a string containing the current
values of the sequence.
SGA,i,d..d
Sets the Gain of the module, channel "i"
Set GAin
i = A, B or * (* means: both channels)
d..d is the value of the Gain; the leading
zeroes can be omitted.
SGA,10
Default
The default Gain at power on is 10.
Note:
If the channel designation is omitted, the
Gain is set on the active channel (or
channels).
ADJ,i,1
Performs a measurement immediately to
compensate the offset.
Note :
The input will not be short-circuited. It is
therefore up to the user to either externally
short the input or send the ISC command
before this operation. Failing to ensure
clean initial conditions may lead to poor
measurement results and high drift.
When the selected integrator channel
enters
the
Offset
Adjust
Mode,
it
automatically performs an average of the
input signal during 2 seconds. This
averaged measurement is used to zero the
offset.
Once the mean is achieved, the instrument
