Picosecond 6110D reference flat pulse generator
. Settling Time Calibration Standard to < 0.02% in 10 ns
The Model 6110D Reference Flat Pulse Generator (RFPG) produces a known, clean, Reference Flat Pulse (RFP). This pulse switches from 500 mV (into 50 W) to 0 V with a 90% - 10% falltime of 425 ps. The settling time is 3 ns to within 0.2% and 10 ns to 0.02%. The 6110D RFPG can be used as a calibration standard for determining the settling time, transient response of oscilloscopes, waveform recorders, A to D converters, etc. The RFP waveform shown below, including the precursor, undershoot, perturbations, and settling time, is mathematically predictable. The design of the 6110D RFPG is based upon a National Bureau of Standards (now NIST) RFP generator [Ref 1,2]. Due to the
use of a much lower capacitance Schottky diodes in the PSPL design, the settling time of the 6110D is considerably faster than the original NBS generator. The 6110D circuit is built into a remote pulse head module. A one-meter cable is provided to connect the 6110D to a driver pulse generator. This allows the RFPG to be connected directly to the circuit or instrument under test. Do not use any coaxial cables between the RFPG and the test point. The pulse response of even short cables will drastically affect the settling time of the RFP.
