– Key Features
Split-screen display enables simultaneous viewing of multiple traces and measurement windows. One-button measurement routines simplify operation for common tasks. Dual interfaces provide versatile connectivity options.
Option 041 (GPIB and Parallel Printer Interface): Enables remote control and automated test system integration through digital communication and data printing capabilities.
Option 101 (Fast Time Domain Sweeps and Analog+ Display): Accelerates time-domain sweep speeds for transient signal analysis. Analog+ mode facilitates intermodulation product viewing and residual carrier level adjustment. Required for TV sync trigger capability when paired with Option 102.
Option 105 (Time-Gated Spectrum Analysis): Provides external trigger-based selective data acquisition with gate delay from 1 µs to 65.535 ms, enabling analysis of time-variant signals within defined temporal windows.
– Typical Applications
Downloadable measurement personalities support cable TV/broadcast analysis, component testing, electromagnetic compatibility (EMC) assessment, lightwave measurements, and wireless communications evaluation.
