Having a bit of trouble getting TTL modulation from the flexmod n2. I applied 5 volts from a regulated ps to the driver and adjusted the bias and gain currents. Using my function generator I set a 0-5v square wave signal and applied it to the mod+ and mod- terminals. I hooked up the output terminals to an oscilloscope and observed that there was no square wave modulation at the output (i used a single regular diode as a test load). The output is just a regular DC signal.
I tried searching for an answer but came up with nothing. Maybe you guys can help.
