GW Instek USG-LF44 - RF Signal Generator

GW Instek debuts the brand new USG-Series RF signal generator, which comes with five models to meet users’ requirements and is a pocket-sized, and USB interface compatible RF signal generator with the frequency range from 35MHz to 4400MHz. The USG-Series provides continuous wave (CW) signal outputs without any signal modulation function. The built-in electronic attenuator of the USG-Series allows an adjustable power range from -30dBm to 0dBm. The USG-Series has several operational modes including fixed frequency, frequency sweep, frequency hopping, and power sweep. The USB-Series RF signal generator, with the frequency bandwidth limitation, provides lower harmonic output performance.

Figure 1 shows the test result of USG-LF44 simultaneous power sweep and frequency sweep. The test result covers the frequency range from 35MHz to 4400MHz and the power range from -30dBm to 0dBm. The yellow trace illustrates the test result of maximum hold and the pink trace shows the test result Figure 1 of signal output.

•  The USG-Series RF signal generator, with the excellent performance, is a valuable and economical choice to meet users’ test requirements.
• 
  The USG-Series features the spectral purity of 107dBc/Hz, dwell time of 1ms, frequency offset setting of ±50kHz, and frequency resolution of 10kHz.
• 
  Utilizing the PC USB interface to supply power and to control USG yields the convenience of rapid installment for all electronic products under a plug-in and use basis.
• 
  The clearly explained application software helps users quickly familiarize the operational method that greatly reduces learning time.
• 
  The USG program compatibility has been enhanced by the PC application program supporting different operating systems such as Windows 2000/XP/Vista/7/8, Linux, Android & Mac OS X.

Target Markets and Applications

USG-Series signal generator has a very wide application range. Educational institutions and electronic component manufacturers use signal generator for the following applications:

• As the reference signal source for phase-locked loop and analog-to-digital converter.
• 
  As the local oscillator for frequency converter and IQ modulator.
• 
  Using two or more USGs for amplifier inter-modulation distortion test.
• Connecting with an external amplifier to produce an interference signal source.
• Connecting with an external attenuator to produce a feeble signal to test the sensitivity of a receiver.
• Connecting with a USB power sensor to test insertion loss for RF components such as cable, filter, and
  attenuator, etc.
• As the tracking generator for spectrum analyzer to conduct measurement functions of scalar network
  analyzer.

		A USG CD-ROM provides dedicated PC application programs, which were developed under JAVA software* structure. Users must install JAVA software to use USG PC application programs, which support operating systems such as Windows 2000/XP/Vista/7/8, Linux & Mac OS X through the USB interface.
		Users can download USG APP to smart phone or tablet with Android 4.0 or above. To operate USG, use USB-OTG connecting cable to connect tablet (or smart phone) and USG. The Android APP application software for the USG signal generator is available on Google Play Store. https://play.google.com/store/apps/details?id=com.gw.usg
		The USG signal generator can be designated as the tracking generator for GSP-730 spectrum analyzer to conduct measurement functions of scalar network analyzer. A USG CD-ROM provides PC application programs for the Primary RF software. Users can, using a Windows OS computer, control USG and GSP-730 via the Primary RF software. The NI-488.2 software** must be installed first before installing Primary RF software.
