Provided you have conditioned the signal to be Pi safe (low of 0V, high of 3V3) you can read it at any GPIO.
My piscope program will allow you to view and capture the signal.
Please be aware that the signal may or may not have the (38kHz approximately) carrier wave. It depends where you are tapping off the signal at the remote controller.
The OP wants to read the output voltage of the IR LED output of his CN1082 remote. So he connects one wire seemingly directly to one end of the IR LED (not sure anode or cathode, he says "+") to Rpi GPIO pin 18, another wire to Rpi Ground.
The OP had no luck. How to fix it?

Not sure if the OP's remote uses 1.5V x 2 = ...
Simplest way I can think of it to set the Pi to have a network connection via USB - note this is only available on some Pi computers such as the Zero, A, CM and Pi 4B via the USB C socket.
with one space between it and rootwait in /boot/cmdline.txt
The Pi will then connect to the Mac ...
If you are on Windows I suggest you to try out this script.
It is mostly based on the "arp -a" command, but it saves you some extra digging and helps you when your Raspberry is not already in the Arp table.
Create a text file with the following content and rename it as find_raspberry_pi.bat
:: This script, run from a Windows (10) machine, finds a ...
As previous contributors have said, if you start the process using nohup you will be able to disconnect and it should still run:
nohup <program name> &
If you have already started the program through PuTTY and have now want to be able to disconnect, you can use the disown command:
ctrl-Z to suspend the process
bg # run the process in the
