Model 1018B a direct reading peak power meter, measures power on a single pulse, repeating pulses, or CW. Three trigger modes (Internal, External, and Free Run) plus an adjustable measurement gate, which can be placed at the desired point by use of trigger delay circuitry, add to its versatility. The 1018B measures and digitizes its readings in only 1 ms and readings can be made at rates up to 500/s. Single pulses down to 200 ns can be sampled and displayed in either dBm, mW, or on the 1018B’s three digit readout. Three fixed “Coupler-dB” ranges can be used with external couplers or attenuators to extend the measurement range for high power applications. A GPIB option (05) can be specified, which will provide an isolated data output, as well as bus control for the trigger and trigger delay.
