Comb Generator for Radiated Signal Reference Source

Features

• ▸ Radiated reference signal source for OATS, SAC, and FAC — broadband EMC reference for fast pre-test validation of radiated emissions test sites between formal NSA calibrations.
• ▸ Frequency range: 5 MHz to 1.5 GHz — covers FCC Part 15, CISPR 32 / EN 55032, and most commercial radiated emissions test bands.
• ▸ Fixed 5 MHz step size for general-purpose verification — produces fundamental and harmonics every 5 MHz across the 1.5 GHz span. Two practical advantages of the larger step: (1) the output remains usable to at least 1.5 GHz, and (2) energy density per MHz is lower, so harmonics stand out cleanly on EMI receiver displays without crowding adjacent bins.
• ▸ Pen-style cylindrical chassis — compact 7″ × 1.2″ (17.8 × 3 cm) cylindrical body, 1.5 lbs (0.7 kg), easily mounted on tripods, antenna positioners, or turntables.
• ▸ Two interchangeable monopole antennas (5-inch and 12-inch) — supplied for optimized radiation across the lower- and higher-frequency portions of the 5 MHz to 1.5 GHz range.
• ▸ Battery operation, 18+ hours per charge — internal 6 V / 1 Ah NiMH battery eliminates external power cabling that could disturb the radiated signal pattern.
• ▸ Automatic low-battery shut-off — the battery monitoring circuit shuts the unit down before output level degrades, protecting baseline data integrity.
• ▸ Stable, repeatable RF output — 20 ppm frequency stability, ±0.1 dB amplitude stability, and <1 dB time stability over 12 months allow direct comparison of measurements taken months apart.
• ▸ External LED indicators — battery low and power on LEDs confirm operating status during chamber walk-throughs.
• ▸ Insertion loss / site comparison source — broadband output also serves as a reference for cable, attenuator, and filter insertion-loss measurements and inter-site comparisons.
• ▸ NIST-traceable calibration — calibration data and certificate ship with each unit; ISO 17025 accredited calibration available on request.
• ▸ Three-year standard warranty — backed by manufacturer support.
