Probes For Pmodia

[yangz3]

Hi,

 

I'm about to buy the PmodIA board. I'm wondering where can I get the probes for the board?

 

Thank you.

Hi yangz3,

 

Unfortunately, DIgilent does not stock any SMA cables that you could use with the PmodIA. You would have to get an appropriate cable (Coaxial RF cable) from a place like Digikey or Mouser, or some other electronics supplier.

 

If you're having trouble finding a cable that suits your needs, what you could do is get any sort of cable with a male SMA plug on one end and then strip the other end of the cable and attach your own clip to the (probably) red wire which is connected to the pin on the SMA plug. Alternatively, if you can secure a breadboard jumper wire into the hole on the SMA connectors on the PmodIA, you would be able to successfully measure any impedances because the outside "ring" on the SMA connectors are not actually used in the PmodIA design (as per their schematic).

 

Let me know if you have any more questions.

 

Thanks,

JColvin

Not sure if this helps,
The bag includes a few female wires for you to connect to the header pins:

It really depends on what you are connecting your cable to. 
If you are just looking to use that input (not for high speed, you could use a clip). 
However, if you are looking to do high speed, what you are connecting to will determine what your cable style will be.

... Although really ugly... and not high speed at all, someone suggested using a pin like this.
