Model BH-1 | NIM Tail Pulse Generator (Obsolete)

The Model BH-1 is obsolete , please inquire about our Model 670C as a direct replacement The Model BH-1 is a tail pulse generator which simulates the broad range of pulses encountered in the nuclear field. Typical applications of the Model BH-1 include: determining the proper timing of linear gates and coincidence units, linearity measurements of amplifiers, threshold setting of discriminators and single channel analyzers, and measuring resolution flow noise amplifiers.

Specifications

Frequency

10 Hz to 1 MHz, continuously adjustable.

External Trigger

Requires 1 volt, positive pulse.

Single Cycle

One pulse occurs each time the push button is pressed.

Single/Double Pulse

This toggle provides for a pulse pair whose separation is varied by the delay controls.
Minimum separation is 50 ns.

Rise Time of Output (10-90%)

20 ns to 50 us (in 11 steps), exponential shape and independent of decay time.

Decay Time Constant of Output(100-37%)

50 ns to 1000 us (in 11 steps), exponential shape and independent of risetime for decay/rise time >10.

Trigger Out

Positive 3 volt pulse, 10 ns rise time, 0.2 us witdh, 50 ohms output impedance.

Delay

-50 ns advance to 10 ms delay (between Trigger Out and leading edge of output pulse).

Output Amplitude

Zero to 9.99 volts maximum. Adjustable by ten-turn potentiometer.
