The 185-2 Plug-In is used with the 445 Oscillator Mainframe. It covers the frequency range of 50 to 200MHz. The unit incorporates a direct reading frequency dial. The 185 has a coupling control that provides for optimization of power transfer to the load. The output power is continuously variable from full rated power down to 50 mW. A low power sample is available for use with an external counter or detector. - Output: 50 W - Accuracy: +/-1% at optimum coupling after 1/2-hour operation at maximum rated power
