PICOSECOND PULSE LABS 4500D FEATURES;

The Picosceond Pulse Labs 4500D is a picosecond step generator. The 4500D Picosecond Step Generator produces extremely fast, high amplitude step function pulses. They are completely solid-state using avalanche transistors and step-recovery diodes. These generators were originally designed for use in measuring the step response of wide-band networks and instruments such as coaxial cables and traveling wave oscilloscopes. Reach out to Select-Test.com for further assistance. The design goal was to build an extremely stable pulse generator which produced a very clean step function. The duration of the step is 10ns which is usually sufficient for the characterization of very broad-band systems. It is not intended that the step be used for measurement times longer than 10ns. After 10ns, the output pulse has a ragged falling edge waveform with a slow 2ed transition duration of 35ns. These generators are complete instruments including regulated power supplies, internal rep. rate clock, trigger and step output circuits. They can be operated at repetition rates from single shot up to 100 kHz and also driven by an external TTL sync pulse. A trigger output pulse is provided in addition to the step pulse output. The delay between the trigger and the step output is fixed at 100ns. It features a timing jitter of less than 10ps.

FEATURES :

·       Rise time (10%–90%): ~ 100 ps (125 ps max)

·       Output amplitude (into 50 Ω): 35 V typical, 30 V minimum

·       Amplitude adjustment: 35 V down to ~ 3.5 mV in 1 dB steps

·       Timing jitter: ~ 1.5 ps rms

·       Step / pulse duration: 20 ns with internal 50 Ω charge line; external charge lines allow 1 ns to 250 ns durations

·       Fall time (trailing edge): ~ 1 ns

·       Overshoot / topline perturbation: ≤ 2% typical

·       Polarity: Positive output (standard)

·       Repetition rate: 1 Hz up to 100 kHz

·       Trigger output: ~ 10 V into 50 Ω, exponential waveform, ~ 1 ns rise

·       Trigger delay: ~ 100 ns fixed; adjustable from 0 to 110 ns in 10 ns increments

·       Connectors:

o   Pulse out: SMA

o   Trigger in/out: BNC

o   Charge line in/out: SMA
