The PC-2X is a handheld RF signal generator. It generates two CW carriers that are extremely clean and stable. Compared to the PC-2, this unit has a brand new design, easy to use, rechargeable battery, and switchable software frequency. 
 
The PC-2X is popular with CATV installers and service technicians who align and test the return path. It is also handy for measuring the insertion loss of cable, splitters, taps, and more when used in conjunction with a signal level meter or spectrum analyzer.
