GW Instek USG-LF44 — USB RF Signal Generator
The GW Instek USG-LF44 is a USB-powered RF signal generator with continuous wave (CW) output. The instrument delivers a single, stable signal in the frequency range of 34.5 MHz to 4400 MHz and is controlled via USB from a PC or mobile devices with supported software.
Features and Operation
The USG-LF44 generates CW signals without built-in modulation and features an integrated electronic attenuator for adjusting output power. The device supports multiple operating modes, providing flexibility in measurement and test setups. Control is via USB 2.0 (Mini B) and includes/available PC and mobile applications for various operating systems.
- Frequency range: 34.5 MHz – 4400 MHz
- Output: continuous wave (CW)
- Output power range: -30 dBm to 0 dBm (in 1 dB steps)
- Frequency resolution: 10 kHz
- Phase noise: -107 dBc/Hz at 100 kHz offset (as stated in manufacturer's specifications)
Use a USB connection to control the USG-LF44 from a PC or via the manufacturer's Android app on devices with USB-OTG. The software package for the manufacturer's Primary RF and USG applications is stated as supported for Windows, Linux, Mac OS X, and Android.
Typical Applications
The applications explicitly mentioned by the manufacturer are as follows:
- Reference source for PLL and ADC
