Santec TSL-710 - Analog Signal Input

Tunable Semiconductor Laser TSL- 710
6-11
Analog Input LF Mod. RF Mod.
6-6 Analog Signal Input
A function used to ne-tune the wavelength according to the external input voltage.
Input the signal into the BNC connector labeled ”Analog Input” inside the cover at the
bottom of the front panel.
Analog input
Specications
Input voltage range: –1.5 to +1.5 V
Rate of wavelength change: -40pm/V(Typical)
CAUTION
Please cancel the closed-loop wavelength control when using analog input
function.
Refer to “6-1. Fine-tuning” to cancel closed-loop wavelength control.
NOTE
Never apply voltage out of the input level range. Doing so may damage the device.
Specications
Modulation bandwidth: 2 to 100 MHz
Input level: 5Vp-p
Modulation depth: >10% (Typ.)
Input impedance: 50 Ω
