 | PB-5 rep-rate accuracy |  |
 | The Model PB-5 uses an RC-Oscillator, a bistable multivibrator circuit, as a rep rate generator that is not crystal controlled. Consequently the display settings for frequency (and delay and width which use the same type of multi-vibrator circuit) are not |

| Random-rates using the PB-5's External Trigger | |
| The PB-5 can be externally triggered at random rates. Its internal rates are regular, repetitious intervals.
If you have our DB-2, random pulse generator, use its Trig Out as the trigger source. If you have another device that produces random rates, |

| Explaining the baseline clamp on the PB-5 | |
| The PB-5 provides a way to clamp the baseline to zero prior to the start of a pulse. In this way, the actual pulse amplitude will be equal to the value set, independent of the rate and decay time settings. If the rate or decay settings do not allow the |

| Can you obtain random rates with the PB-5? |  |
| The internal rates occur at regular intervals. The only way to obtain random rates with the PB-5 is to externally trigger at random rates.
If you have our DB-2, random pulse generator, use its Trig Out as the trigger source. Now the external trigger |

| Some differences between the PB-5 and PB-4 | |
| The PB-5 is completely programmable and the PB-4 is not programmable at all.
The programming of the PB-5 lets you select all operating conditions for the output pulses - both time and amplitude domain parameters. The PB-5 uses DAC's instead of potenti |

| “Dropped” Pulse in the PB-5 | |
| Because most pulse processing applications are random and not periodic, the design of the PB-5 is such that floating point calculations occur between each ramp step. The amount of time this calculation takes is non-deterministic since the time required to |
