The Diamond SX-1100 is an insertion type meter measuring SWR or output power. Peak envelope power (PEP) can be monitored in the SSB mode. This meter covers these four bands selected on the front of the meter: Sensor 1: 1.8-160 MHz, Sensor 2: 430-450, 800-930 and 1240-1300 MHz. The sensor switch is on the back panel. Continuous power capacity is 1.8-100 MHz 100 watts, 100-160 MHz 70 watts and 430-1300 MHz 100 watts. 200 watts is supported, but only for intermittent use. A power range switch selects 5, 20 and 200 watt scales. Minimum power for an SWR measurement is 1 watt below 160 MHz and 2 watts about 430 MHz. Sensor 1 features UHF (SO239) jacks and Sensor 2 features low-loss N jacks. Insertion loss is less than 0.2 dB below 160 MHz and less than 0.15 dB above 430 MHz. 12 VDC at 50 mA is required for illuminated display and band indicator. A DC power cable is supplied.
