The J0SSAG13 from SAF Tehnika is a mmWave Handheld RF Signal Generator with a frequency range from 17 to 24.3 GHz. It has a frequency resolution of 1 MHz and delivers an output power from -3 to 10 dBm which can be adjusted in 1 dBm increments. This CW signal generator has an accuracy of ±10 ppm and a phase noise of -80 dBc/Hz.
These CW sources have an intuitive, interactive GUI with instant on/off functionality, and the resistive touchscreen allows for operation even with gloved hands. The built-in LiPo battery allows continuous use for three hours or more. The module measures 5.04 x 3.2 x 0.94 Inches and is lightweight ideal for field use.
The extremely portable signal generator is a valuable tool for indoor benchtop use, or outdoor for antenna testing, alignment, and line-of-sight verification. The output signal can be fed into a directional antenna for subsequent detection at a far point microwave dish, for instance, when paired with a SAF Spectrum Compact signal analyzer. For precision fieldwork, external low-pass filters may also be attached to the SMA output connector.
