The 6062A Synthesized RF Signal Generators covers the frequency range of 100kHz to 2.1GHz in 20Hz steps (10Hz steps below 1050MHz). Specified amplitude accuracy is ±1.5 dB from -127 dBm to +13 dBm. The unit has amplitude and frequency modulation as well as phase and fast-rise pulse modulation. The instruments gallium arsenide pulse modulator generates fast, high quality pulses for testing of pulsed communication and navigation circuits. It employs a design that can generate very narrow pulses, limited only by the modulator's 15 ns rise and fall time.
