LEDs increases. Up to 5 watts of drive is required to produce the POWER (W) full 100 watts output from the KXPA100. If more than 5 watts is applied, enable the input attenuator (3 dB ATTEN) {17} by sliding its switch to the ON position. -
Page 8: Monitoring
Standing wave ratio (SWR) of the load and output power are displayed on LED bar graphs. Excessive levels may trigger a fault and either bypass the KXPA100 or shut the power off (see Fault Conditions below). Also two green LEDs indicate whether the amplifier is in standby (STBY) or operating (OPER) mode. -
