Hi folks. I have this power amplifier that I would like to hook up to a function generator and send a 125 khz signal. I've been reading the doc's and I can't understand what exactly I need to do to communicate with it through the db9 port or maybe the front balanced input port. https://aetechron.com/IND-RESEARCH-7114.shtml#download Here is everything I can find on the device. My function generator will be a Digilent Discovery 2 that has 2 channel BNC out. Is it as simple as getting a bnc to db9 adapter and sending the wave normally or does more need to be done than that? Thank you for taking the time to look at this.

I had a talk with Jacob at Techron and he said it's okay to just send a continuous 125khz sine wave just normal through the unbalanced bnc in the front of the box. I don't know a whole lot about the voltages yet but my analog discovery can only do a max of +/- 5v but the amplifier can take up to +/- 10v but I might not need that much. I also just discovered from a colleague that you can't use the BNC adapter board on the Analog Discovery 2 to send out a wave, it is only for reading so I hooked up a break out cable for all the pins and what I have to do is wire individual pins to an aligator clip to bnc cable and route the signal that way. In this case it would be W1 pin which is the yellow cable.

Did you look at section 6 of the owners manual. It looks like everything you need is right there. There are a few pins that you would need to worry about. Mostly there are two pins that you need for controlling the min to max setting using 0-10VDC signal. This should be very easy to do. You would need something to control the signal voltage.

Would anyone know how I might communicate with an AE TECHRON 7114 through the db9 port?

Solved!

Thank you very much. I'll give the LabJack a go as well. I will probably need it for another part of this project as well a bit later on.
