12GHz Tracking Generator


SKU: TG12000 Category:


The new TG12000 REV9 (2021 version) is a generic RF Tracking Generator that can be used with many existing Spectrum Analyzers. It covers a range from DC to 12GHz in three bands via two front SMA outputs. It also functions as a standalone RF signal generator from 25 to 6000MHz.

The TG12000 can replace the Agilent HP 85640A external tracking generator and adds a Signal Generator function as well. In addition it covers the 2nd and 3rd band, which the 85640A does not, providing a TG signal to 12GHz. A very good troubleshooting and measuring tool to easily characterize filters and attenuators!

Note: The TG12000 is considered a specialty product and can take a few extra days to ship.

*Units without LO output option must be modified with a directional coupler. This should affect the internal LO by around 1.0dB. We recommend the ZADC-10-63+ inserted after the last power amp. We recommend finding the full service manual online for your equipment for reference on how to do this modification.
