BNC/Berkeley Nucleonics PB-4 Precision Pulse Generator NIM Module/Card

Description: BNC/Berkeley Nucleonics PB-4 Precision Pulse Generator NIM Module/Card Comes with what you see in the pictures. If you don't see it, you probably won't get it. Specifications are from BNC and may vary slightly due to upgrades, options, or revisions this unit may or may not have. This unit is fully tested and ready to ship! It is guaranteed to work for 30-days, parts and labor, excluding freight. The Unit's Serial Number Tag Reads: Model Number: PB-4 Serial Number: 12456 Typical Applications: Use as a reference peak for spectrum stabilization Testing base line shifts up to 250 kHz Measuring differential and integral linearity of pulse height analyzers Measuring noise contributions from pre-amplifiers Description: The Model PB-4 is a precision pulse generator designed to test stability, linearity, and resolution of nuclear instruments employed in high resolution spectroscopy. An unusual feature of the Model PB-4, hitherto unavailable in high rep rate precision pulse generators, is the capability of driving 50 Ω loads without affecting the stability, linearity, or pulse shape. Specifications: Repetition Rate: 2.5 Hz to 250 kHz, continuously variable. External Trigger: 0 to 250 kHz. Requires 1 V, posititive pulse, with a rise time of less than 1 ms. Single Cycle: Front panel pushbutton provides one output pulse each time the button is pressed. Delay: 0.25 µs to 10 ms, continuously variable. (Delay is time between trigger out and pulse out.) Pulse Shape: Tall or Flat Top Pulse (by front panel toggle). Tail Pulse: Rise Time (10% - 90%): 0.05 µs to 10 µs, in 8 steps. Decay Time Constant (100% - 37%): 0.5 µs to 1 ms, in 9 steps. Note: Rise and Decay Time independently adjustable for Decay Time/Rise Time < 10. Flat Top Pulse: Width: 0.5 µs to 25 µs, continuously adjustable. Pulse Top Droop: Less than 0.02% with 10 µs pulse width. Rise and Decay Time: Same as Tail Pulse. Pulse Top: Stability: ±5 ppm/°C of full scale or 20 µV/°C, whichever is greater. This specification holds for unattenuated output. When attenuation is switched in, the ±5 ppm/°C is constant, while 20 µV/°C is reduced by the attenuation factor. Integral Nonlinearity: ±0.005% (50 ppm). Differential Nonlinearity: ±0.03%. Amplitude Jitter (Resolution): 0.001% rms (10 ppm). Setability of Pulse Amplitude: 5 ppm Line Voltage Coefficient: Less than 0.5 ppm/V when used with a NIM power supply or BNC Portanim Models AP-1 and AP-2. Amplitude: 0 to 10 V Normalize: Fine and coarse front panel trimmers vary output amplitude by 20%. Polarity: Positive or negative. Attenuators: Four toggles with X2, X5, X10, X10 attenuation, 50 Ω impedance. Output Impedance: 50 Ω ±2%. Amplitude Shift with Duty Factor: Less than 0.03% change up to 50% duty factor. Repetition Rate and Delay Jitter: Less than 0.05%. Trigger Output: 2 V positive pulse, 30 ns rise time, 0.1 µs width, 50 Ω output impedance. External Reference Input: ±11 V maximum. Input impedance 1 K. Primary function is to connect with an external ramp generator to provide a sliding pulse train. Power Requirements: ±24 V at 240 mA. Mechanical Dimensions: Triple-width AEC module 4.05" W x 8.70" H in accordance with TID-20893 (Rev. 3). Weight: 6.5 lbs.
