In the T

TRIGGER
SETTINGS
area you can configure the pulse length and the pause length
for the test trigger.
Here …
the pulse length defines the length between the start of triggering and the stop of
triggering.
the pause length defines the pause between two triggers.
Using the test trigger you can trigger the gate and the laser control to perform the test
measurements.
How to configure the test trigger settings:

Internal gate
Note
The I
NTERNAL
GATE
device page is only displayed if you have activated the application Level
Control (see
).
If you use an internal gate, the G
ATE
ON
parameter defines the length of the columns and the
G
ATE
OFF
parameter defines the gap between two columns.
The columns can be “generated” continuously by the internal gate or instead limited by an
external gate (see
If you use an external gate, the start and end of the gate define the start and end of column
generation. Between start and end the internal gate defines the length of the columns.
How to configure an internal gate:

Encoder and synchronization
3.8.1
Master/slave configuration (synchronization)
If you use two LMS400 as master and slave over the “System” connection, then you must
configure one device as master and the other one as slave.
Notes
On master/slave operation, master and slave must be configured to the same scanning
frequency and angular resolution (see
Once the mirrors have run up, master and slave must synchronise with each other. This
can take up to 120 seconds. Note that until synchronisation is complete, the measured
values supplied by the two devices are not synchronised.
Phase
On the use of two LMS400 in a master/slave system it may occur that one LMS400 received
the beams from the other LMS400 and is affected by the beams.
