The Tektronix ADA400 Differential Preamplifier allows direct oscilloscope measurements of very low amplitude voltages and signals which are not ground referenced. It attaches to a scope or 1103 power supply through a Tekprobe BNC connector.
- 10 µV/div sensitivity
- Typically 100 dB CMRR from DC to 10 kHz
- Selectable bandwidth limiting
- Adjustable differential offset
- "Infinite impedance" mode in the two highest gain ranges
