How to Measure Current in a Hall Bar Device Using SR830 Lock-in Amplifier?

TL;DR

How can i use sr830 amplifier to measure current(I) of a hall device?

I want to measure the current of hall bar device using sr830 LIA. it is possible with sr830 to measure current but how ?

Welcome to PF.

What have you found in your research on this so far? How much have you used Lock-In amplifiers in the past, and for what tasks? What does your experiment look like so far for measuring the current of your Hall sensor (versus magnetic field?)?

The SR 830 has a current measurement mode shown in the user manual. However, most Hall devices provide an output voltage.
Do you want to measure a DC or AC magnetic field?

Thankyou all for the reply
actually what i want to do was put sin out at one voltage terminal and A at the gating electrode, From there measure the current. basically it will be acting as a capacitor. the resistance between the voltage terminal and gate electrode is in Mohm. So by using A(Current input 10^6 or 10^8) i think it is possible but it might show overload in X and Y

I'm sorry but I don't understand what you want to do. Could you post a diagram?
