Santec TSL-210 - 9-8 Wavelength Calibration

TUNABLE LD LIGHT SOURCE TSL-210
9-15
TSL-210 has the current control mode and the power control mode. In either case, feed
back loop control to stabilize optical output power inside is conducted. In the case to
use low frequency modulation, if feed back loop is not removed, external input voltage
is handled as uctuation, so preferable modulation is not available. Remove the feed
back loop in the above procedures before use.
Specications:
Tuning band range :0-10KHz
Input level :±1V
Modulation efciency :100mA/V
Input impedance :4.7k
Ω
NOTE
9-8 Wavelength Calibration
This product is equipped with wavelength calibration function to calibrate difference in wave-
length with other measuring device and calibrate the wavelength monitor of the TSL-210.
Press SHIFT key. (This key toggles ON/OFF the SHIFT function.)
When the key is pressed, SHIFT LED is lit, and the next key entry is ready.
When the SHIFT LED is lit, press the wavelength calibration key.
When the key is pressed, all the displays in the optical output power display panels change into
“-”, to show that the unit is in wavelength calibration condition. Make sure that the rotary
encoder change key is set at wavelength selection. Using the rotary encoder, select the wave-
length to be calibrated.
