The F-120-2 can be used for coupling large CW currents as well as pulse transients. For CW Bulk Current Injection, the useable frequency range is 10 KHz-230 MHz with the insertion loss of less than 10 dB from 500 KHz-230 MHz. The input power rating is 125 watts CW for 30 minutes. Because of the broad bandwidth the F-120 can also be used for coupling transients with 2 nanosecond rise times and 30 nanosecond pulse widths onto lines under test.
