The Model PB-5 replaces the BL-2. Along with a suite of features and modes, the PB-5 is widely respected for its 155 uV amplitude resolution
- Fast, Linear, Stable
- 5 ns Minimum Width
- 3 ns Minimum Rise Time
- Double Pulse Capability
- Adjustable Rise and Decay Times
- Repetition Rates up to 50 MHz
The Model BL-2 is a versatile, tail pulse generator capable of simulating the outputs from a wide range of detectors, photomultiplier tubes, and related electronics. It offers good linearity and stability, and fast, narrow pulse capability. Having a broad range of rise and decay times, the Model BL-2 can simulate the shorter pulses of plastic scintillators and lead glass as well as the longer pulses of NaI, many liquid scintillators, and amplifier outputs. The Model BL-2 enables the user to check electronics for linearity, resolution, rise time effects, count rate effects, and overload effects. Of particular interest to those that wish to check pulse pair resolution and count rate effects is that the BL-2 can operate in a double-pulse mode, with a pair of pulses having an adjustable separation that can be as low as 10 ns. Since repetition rates are variable to 50 MHz, a 100 MHz repetition rate is possible by double pulsing. The high repetition rates enable the user to quickly accumulate the large number of counts needed for good statistics.
Other features include an:
- External Reference input, where an incoming signal controls the output pulse amplitude
- External Trigger mode, where an incoming pulse triggers an output pulse
- External Drive mode, where an incoming pulse controls both output pulse width and timing.
