Rohde & Schwarz SMHU High Accuracy Signal Generator

Overview

The Rohde & Schwarz SMHU is a high-performance RF signal generator designed for demanding test and measurement applications. With frequency coverage to 4.32 GHz and exceptional spectral purity, the SMHU is ideal for receiver testing, local oscillator applications, and noise measurement systems where signal integrity is critical.

Key Features

• Frequency range: 100 kHz to 4320 MHz with 0.1 Hz resolution
• Frequency setting time: below 10 ms
• Fast sweep mode: up to 200 user-defined frequencies in less than 1 ms per setting
• Exceptional spectral purity for adjacent-channel and out-of-channel measurements
• FM modulation: DC to 1 MHz with minimal frequency offset in FM DC mode
• AM modulation: DC to full modulation frequency range with flat frequency response for VOR/ILS receiver testing
• Pulse modulation: 20 ns rise/fall times (typical <10 ns for frequencies >200 MHz) with 80 dB on/off ratio
• Phase offset: adjustable in 1° steps

Applications

• Receiver selectivity and sensitivity testing
• Low-noise local oscillator reference applications
• Reference signal for noise measurement systems
• Telemetry and satellite communications testing
• Radar and microwave link system testing
