The PB-5 sets a new standard for precision pulse generators. It offers full digital controllability with a built-in ramp generator for linearity testing. It provides tail and flat top pulses with outstanding integral linearity and extremely low amplitude change with temperature. The PB-5 is capable of testing the stability, linearity and resolution of the most demanding spectroscopy circuits and instrumentation. It is the successor to the industry standard, PB-4 pulse generator.

Main Menu

The 4x16 LCD display, keypad, and a spinner knob provide a user interface that is easy to use. RS232 interface is also standard along with memory that will store and recall nine complete pulse setups.

Pulse Settings

The pulse repetition rates, which are variable over a broad range, go up to 0.5 MHz. The higher rates are required when testing for MCA and PHA linearity because of the high number of data points required for a statistically valid test.

Model PB-5

Trigger Mode

The Model PB-5 pulse generator provides unprecedented performance in a precision pulse generator. It includes a full-featured, highly flexible ramp generator and programmability. As a precision pulse generator, the PB-5 surpasses or equals all existing designs in the important performance areas of resolution, linearity and stability.

Model PB-5

Ramp Settings

The built-in ramp generator allows you to control ramp duration, the number of ramps and the ramp limits. Now you can test the entire range of your system or just a portion of that range. This ramp generator and precision pulse generator combination allows you to tackle the most demanding applications.
