Measurement with Agilent's High Frequency Probe 85024A

85024a

Hi,

Have anybody worked with Agilent's High Frequency Probe 85024A along with 10:1 voltage divider?

I am using this assembly to measure power at 2.4GHz in a 50 ohm system in parallel with antenna of 50 ohm impedance.
kindly help me in calulating the correction factor for the signal measured using probe with voltage divider.

Thanks,

It is impossible to know. It depends on if your hand is near the antenna, etc. You can replace the antenna with a 50 ohm connector and try to calibrate it.

If I had to know power levels for sure, I would use these test points instead. They disconnect the antenna when you insert the test connector.

Hi,

I have attached one bmp file to show the system.
Probe impedance is 94.7 ohm at 2.4GHz.
In the shown image at PC board stage, we have two type of data, one with SMA connector with antenna disconnected, this represents the actual power feed to the antenna.
Another is with probe + 10:1 divider assembly with antenna conected.
I need to have the relation between the two.

Thanks,
