All values relate to a one-hour warm-up period.
Software limits of range. Actual range possible depends on the physical load,
thermistor type, and TE module used.
Accuracy gures are quoted for a typical 10k thermistor and 100µA current setting.
Accuracy gures are relative to the calibration standard. Both resolution and accuracy
are dependent upon the user-dened conguration of the instrument.
Accuracy depends upon the sensor model selected, the calibration standard,
and the user-dened conguration of the instrument.
Over any one-hour period, half-scale output, controlling an LDM-4412 mount at 25°C,
with 10k thermistor on 100µA setting.
Over any 24-hour period, half-scale output, controlling an LDM-4412 mount at 25°C,
with 10k thermistor on 100µA setting.
Into a 1 load.
Measured at 1A output over a bandwidth of 10Hz to 10MHz.
To use RTD sensors with model 39034, order TSC-599 Temperature Sensor Converter
accessory.
Nominal temperature coefcients, It and Vt, apply over the rated IC temperature
sensor range.

Software limits of display range.
Using a 100k thermistor, controlling an LDM-4412 mount over –30°C to 25°C.
Using a 10k thermistor, controlling an LDM-4412 mount over 0°C to 90°C.
Model 39034 has TEC Voltage measurement through GPIB only.
Voltage measurement accuracy while driving calibration load. Accuracy is dependent
upon load used.

IC and RTD temperature sensors
Standard GPIB IEEE interface
The LDC-3900 Modular Laser Diode Controller features
four channels with eight isolated outputs for controlling
multiple laser diodes. Modules include current sources with
maximum outputs from 200mA to 8A, TE (thermoelectric)
controller modules with up to 32W of power and voltage
measurement, and controller modules with laser control
from 200mA to 2A and integrated 12W TE control.
An independent power supply powers each channel,
providing protection and stability for your laser diode. Every
module incorporates low noise, high stability performance,
and ILX Lightwave’s unmatched laser diode protection
topologies including independent current limits and laser
diode shorting relays.
Remote communication through an IEEE/GPIB interface
simplies testing and control of multiple devices. LabVIEW®
drivers are also available for any combination of mainframe
and module.
