GW-INSTEK USG-LF44 RF signal generator
The GW-INSTEK USG-LF44 is a USB-powered RF signal generator for tasks requiring a stable signal in the range of 34.5 MHz to 4400 MHz. It is used to create a CW signal, i.e., a pure carrier signal without modulation, making it suitable for testing or adjusting RF equipment under controlled conditions.
It can operate in several modes, so you are not limited to a single fixed frequency. You can use fixed frequency, frequency sweep, frequency hopping, and power sweep. The output power can be set from -30 dBm to 0 dBm in 1 dB steps, allowing the signal level to be adjusted for specific measurement tasks.
Control is via USB 2.0 Mini B, and the unit is powered via USB. GW-INSTEK also provides PC software and an Android app for operation, allowing it to be flexibly integrated into both laboratory and development work.
The RF output uses a 50-ohm N-type male connector. A phase noise of -107 dBc/Hz at 100 kHz offset is specified, which is a relevant characteristic when the signal needs to be stable and useful for precision measurements.
A datasheet and product video from the manufacturer are included, which can be used to review technical details and practical operation.
