шт.

Генераторы импульсов Tektronix обеспечивают сочетание короткого времени нарастания и высокой амплитуды с невероятной целостностью сигнала. Приборы имеют регулируемую длительность импульсов и доступны в исполнениях с ручным управлением или с управлением от ЭВМ.

Описание Характеристики Файлы

The PSPL10000 Series Pulse Generators offer premium signal integrity with convenient front panel or computer control. The high voltage outputs have 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.

Notes:

The duration and delay values displayed on the front panel LCD and programmed over the GPIB are only to be considered “nominal” values and not absolute values. The duration and delay parameters do exhibit some thermal drift, rep rate dependency and interaction. There will be some loss in amplitude at minimum pulse durations. The amplitude tolerance of ±0.2 V holds only for > 2 ns durations. 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.
