Model 4121 B
Gated Integrator
- 1 ns minimum gate width
- 80 kHz max trigger rate
- Linear or Exponential averaging
- Input offset control
- Normal or Baselilne sampling modes
- Built-in trigger generator
- Pulsed laser experiments
- Phosphorescence decay time studies
- Precison signal sampling
This model is an ideal component for building boxcar averager systems. It includes a wide bandwidth variable gain AC/DC coupled input amplifier with offset adjustment and a high speed sampling gate with variable width and delay controls. It operates in normal or basline sampling mode and features a switch-selected choice of how many samples are included in the averaging process.
