Agilent/Keysight 1727A

The Keysight 1727A is a 275 MHz analog oscilloscope engineered for signal visualization and waveform analysis across laboratory and field environments. This dual-channel instrument delivers flexible input impedance selection (50-ohm or 1-Mohm) to accommodate diverse signal sources. The vertical deflection range spans 10 mV/div to 5 V/div at full bandwidth, while the timebase provides 24 sweep ranges from 10 ns/div to 0.5 Sec/div for detailed transient and low-repetition-rate signal capture.

Technical Specifications

• Bandwidth: 275 MHz


• Channels: 2


• Vertical Deflection Factors: 10 mV/div to 5 V/div (full bandwidth)


• Sweep Ranges: 10 ns/div to 0.5 Sec/div (24 ranges)


• Input Impedance: Selectable 50-ohm or 1-Mohm

Key Features

• Single marker delayed sweep with delta time measurement capability


• Variable persistence and storage modes for transient signal analysis


• Multiple display configurations: CH A, CH B, ALT, CHOP, A+B, and A vs. B


• Reference amplitude markings at 0%, 10%, 20%, 80%, 90%, and 100% for rapid transition time assessment


• Dual reference lines positioned five divisions apart at 0% and 100% amplitude

Typical Applications The 1727A supports precision timing measurements, pulse characterization, and multi-channel waveform comparison in development, troubleshooting, and field service environments. The selectable input impedance enables measurement flexibility across high-impedance circuits and low-impedance transmission line systems.
