DC power supply with DE-9 connection

AI Thread Summary
A user seeks a cost-effective solution to power a photodiode/amplifier module with a DE-9 connection, as the manufacturer's power supply is too expensive. The lab only has standard laboratory power supplies with positive, negative, and ground outputs. Suggestions include wiring a DB-9 connector to the lab power supply, as many electronics suppliers offer the necessary components to create custom cables. The discussion emphasizes the feasibility of using standard supplies to power the module. Overall, users are encouraged to explore DIY solutions for compatibility.

I have a photodiode/amplifier module, which has a D-sub connection for the power supply. The manufacturer sells a power supply, but it is out of my budget range, and the lab only has standard laboratory PSU's (+V,-V, gnd). Is there any connections so that I can use this module with my power supply? The DE-9 connection only uses 4 prongs (+,-,gnd, case gnd).

Thanks for any suggestions.

Do you mean that you just want to wire up a DB-9 (not DE-9) connector to your lab power supply? Lots of electronics supply places carry DB-9 shells and pins so you can make your own cables up. Is this what you mean?

thats it, thanks berkeman
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
