LabVIEW program for TLB-6300-LN Velocity Tunable Laser Controller

[KarenZL]

Hello,

I have a photodetector (avalanche photodiode--APD) connected to my computer via a NI-USB 6251 and I also have a velocity tunable diode laser controller (TLB-6300-LN) with GPIB which I controll with a LabView vi. I'd like to aquire a program that can obtain the readout from the voltage NI-USB 6251 for APD and at the same time record the spectrum when APD receives a signal.

Could you give me any suggetions for the program? Any help will be really appreciated.

As i understood, you want to obtain the signal from your Photodetector and ur Laser, Here i have some equation, u are using the laser as a source so, are u have Monochromator or u just adjust the wavelength using the tunable Laser? If u just using detector and Laser , i think it's easy to put detector VI and Laser Vi to be as one VI. Make sure u should make it as as sequence, i means that select the wavelength (Laser) then get the detector signal.
it will be good if u attached ur VIs here.
thanks
