I got from my drawer last night a vintage Brainmaster 2E I bought late 1990s that I used only a few times during that period. It has serial port at back. I don't know if it will work using a USB to serial port adapter connected to my laptop. Do you think it will work?
My question concerns the gain of the amplifier and the noise. It says above:
Notch Filtering: 40 Hz cutoff
Common Mode Rejection >100 dB
Gain 20,000
Sampling 8 Bit
Input Impedance 10 M ohms
How does it compare say to your voltmeter? What is the gain of a regular voltmeter? It has this chip.
Familiar with it?
I just want to know how it compares to modern amplifier and whether it's worth taking the trouble to maybe buy an old pc to run it. Is it very ancient and maybe the gain of regular voltmeter is double it? Or still much less?
