PSPL10300B Datasheet

The PSPL10300B Pulse Generator provides high amplitude positive or negative pulses with convenient front panel or computer control. It has an adjustable baseline to provide up to ±5 V DC offset, or allows for external control of the baseline up to ±50 V. The output has fast edge rates, smooth transitions and minimal overshoot & ringing. Adjustable output levels are obtained using internal step attenuators, ensuring consistent signal shape at all settings. The outputs are designed for a 50 Ω impedance, but can safely drive any load from a short circuit to an open.

The performance parameters listed here are typical values, parameters are guaranteed only when maximum and/or minimum limits are given.

Parameter Value
Polarity Positive or negative
Amplitude into 50 Ω (See Notes) 4.5 mV to 50 V positive, -4 mV to -45 V negative, adjustable in 1 dB steps
Amplitude accuracy, into 50 Ω (full output amplitude) ±2 V positive, ±3 V negative
Baseline Adjustable from -5 V to +5 V in 1.25 mV steps, external input provided for user-supplied offset of ±50 V
Transition time, leading edge (10 – 90%) 300 ps, 325 ps max.
Transition time, trailing edge (10 – 90%) 750 ps, 1 ns max.
Reflection coefficient 30% during pulse, +50% after pulse, improves with increasing attenuation
Source impedance (nominal) 50 Ω
Duration (FWHM) (See Notes)
Baseline precursor
Topline overshoot 2%
Topline perturbations ±1% for t
Topline flatness ±0.5% for t > 3 ns (±2% for negative pulse)
Spurious pulse at 120 ns +6% with pulse duration ≤ 20 ns, +30% for pulse duration = 100 ns


The duration and delay values displayed on the front panel LCD and programmed over GPIB are only to be considered “nominal” values and not absolute values. The duration and delay parameters exhibit some thermal drift, rep rate dependency and interaction. There will be some loss in amplitude at minimum pulse durations. The amplitude tolerance of ±2 V holds only for > 10 ns durations. The amplitude has a minor rep rate dependency. Always use an oscilloscope as an independent check of these pulse parameters. The instrument is adjusted and calibrated at the factory in an ambient temperature of 23 °C (±3 °C) at a rep. rate of 100 kHz. The instrument will operate over a temperature range of 0 to 50 °C but will not meet all specifications over this range.
