LinearX LT360
The LinearX LT360 turntable uses an USB or COM connection, please refer to the
manufacturer documentation to the setup of the device. In the option dialog it is
needed to input the communication port to be used.
Some turntables settings, such as the rotation speed and the velocity profile must
be managed using the software supplied with the turntable. For correct
operations with CLIO software the “Display Readout Polarity” setting of
the LT360 turntable must be set on “Unipolar”.
Note: In order to work properly the lt360lib.dll file must be present into the CLIO
installation directory.
The delay parameter (in milliseconds) put the software in a wait state after the
completion of the turntable rotation, this can be useful in a non anechoic space to
let the energy in the room to decay between measurements.
TTL pulse control
Selecting TTL pulse it is possible to control a turntable using a TTL signal from the
PC parallel port. This is valid only for the polar angle and with this selection
it is not possible to use two computer controlled turntables. In this case the
second turntable can be only selected as “Manual”.
The TTL pulse control uses the parallel port or the output port of a QCBox model V.
The information given here apply to the control of the Outline ET/ST Turntable;
