"In the lamdascan function for HP816X instrument driver how do you set the range mode of the power meter (pwm) channel.It sets itself to 0dbm according to the laser power . I have tried using the setinitialrange subvi and also the setpwm parameter subvi.But the program makes no change but sets the range to 0dbm and setting manual of the pwm. So you can't measure power beoynd -40dbm."
