7A13
The Tektronix 7A13 is a "differential comparator" vertical plug-in for 7000-series scopes, i.e. a fast differential amplifier with adjustable DC offset.
Older versions display the comparison (offset) voltage through a mechanical dial, newer versions through an LED panel meter. in addition, this voltage is brought out through a front panel connector so it can be measured externally.
Specifications
- Deflection factor 1 mV/Div – 5 V/Div (1–2–5 sequence)
- Common Mode range: at least +10V / -10V from 1 mV/Div to 50 mV/Div;
- Overdrive Recovery: to within 2 mV in 1µs (at 1 mV/Div)
- CMRR: at least 10,000:1 for 10 Vpp or less, 100 kHz to 1 MHz, decreasing to 500:1 at 10 MHz with 1 Vp-p, 200:1 at 20 MHz with 1 Vp-p.
- Input impedance: 1 MΩ || 20 pF
- Comparison voltage range: 0V – +/-10V
