Low output mode specification - Clean sine wave for precise RF testing: delivers a sine waveform with harmonics below -40 dB relative to the fundamental, reducing distortion and spurious signals in downstream equipment. - Wide frequency range: supports output from 100 kHz up to 350 MHz, covering LF to VHF test needs without changing sources. - Precise level control: output level can be set in 1 dB steps from -76 dBm to -6 dBm for fine-tuned stimulus and reference levels. - Reliable, measurement-friendly performance: designed to maintain signal integrity across the specified range for consistent calibration and testing results. Use scenarios - RF receiver and mixer calibration: inject a stable reference sine wave at a known level to verify gain, response, and calibration offsets with minimal harmonic interference. - Amplifier and system linearity tests: sweep frequency within 100 kHz to 350 MHz while adjusting level in 1 dB steps to assess gain linearity and distortion across operating points. - Lab bench signal source for test setups: provide a clean, controllable reference signal for measurement chains, spectrum analysis, and down-conversion experiments across the full specified band.
