LDS1000 Controller for Laser Diode Sensors
4.1.4 Environment
The performances of an optical sensor greatly depend on the conditions in
which it is used.
The contractual characteristics are specified in the manual that goes with
each sensor of the LDS series.
The operating limits of the LDS1000 Controller are the following:
Operating temperature +15 °C to +25 °C
Humidity 10% to 80%
Storage temperature -10 °C to + 50 °C
Refer to the paragraph entitled “Specification Validity” in each user’s
manual for the performances of the sensors according to the conditions of
use.
4.1.5 RS-232-C and IEEE-488 Interfaces
RS-232-C interface
Baud rate 300 to 19200
IEEE-488 interface
Mode SRQ management
4.1.6 Analog Outputs
Analog outputs are only available if the option has been chosen.
Refresh frequency 2000 Hz
Digital low-pass filter 1 to 2000 Hz
Output range ±10 V
Scale factor 5 mV/incr to 1000 mV/incr
Resolution 0.5 increment
Electronic noise 1 mV rms
Distortion 0.5% (electronic)
Maximum Offset 50 mV typical
Output impedance 10
Discrepancy equivalent to a pure delay of 1.1 msec (without integration).
Attenuation equivalent to the one of an order 1 low-pass filter with
600Hz cutoff frequency.
WARNING: SPECTRAL WITHDRAWAL
The analog outputs use an intermediary calculation stage that is based
on a sample at 2000 Hz. This will limit the use of the LDS sensor for stu-
dying signals that do not have a significant spectral component over
1000 Hz (this sort of component would find themselves “withdrawn” and
would appear for lower frequencies).
4.2 Validity of Specifications
Refer also to the paragraph entitled “Specification Validity” in each user’s
manual for the performances of the sensors according to the conditions of
use.
