Comb Generator 1 and 5 MHz Stepsize

  • The CG-515 is a battery-operated radiated comb generator and EMC reference signal source covering 1 MHz to 1.5 GHz, recognized as an artifact for the Automotive EMC Laboratory Recognition Program (AEMCLRP).
  • User-selectable 1 MHz or 5 MHz step size — choose 1 MHz for high-resolution baseline data or 5 MHz for faster sweeps with cleaner spectral lines on the EMI receiver display.
  • Compact cubic chassis — just 2.9″ × 3.1″ × 3.1″ (7.4 × 7.9 × 7.9 cm) and 0.5 lbs (0.2 kg); the smallest, lightest comb generator in the lineup with two interchangeable monopoles (3-inch and 12-inch).
  • Daily site verification on OATS, SAC, and FAC — quick pre-test checks at a few reference frequencies catch broken cables, blown preamps, and oxidized connectors that would otherwise produce months of invalid compliance data.
  • Automotive EMC pre-compliance verification (CISPR 25) — the AEMCLRP-recognized artifact for inter-laboratory comparison and ongoing site validation in vehicle component test labs.
  • Cable, attenuator, and filter insertion-loss measurements — the broadband output also serves as a stable reference source for chamber-to-chamber comparisons and RF accessory characterization.
  • 18+ hours per charge internal NiMH battery eliminates external power cabling that could disturb the radiated pattern; automatic low-battery shut-off protects baseline integrity. 20 ppm frequency stability, ±0.1 dB amplitude stability.
  • Individually NIST-traceable calibrated; ISO 17025 calibration available on request. Three-year warranty.

Features

  • Radiated reference signal source for OATS, SAC, and FAC — broadband EMC reference source for quick verification of radiated emissions test sites between formal calibrations.
  • Wide frequency range: 1 MHz to 1.5 GHz — covers the principal radiated emissions band used by FCC Part 15, CISPR 32 / EN 55032, and most commercial EMC standards in a single instrument.
  • User-selectable 1 MHz or 5 MHz step size — choose 1 MHz for maximum spectral resolution near the lower limits, or 5 MHz for faster sweeps and easier identification at higher frequencies.
  • AEMCLRP-recognized artifact — used as a reference artifact for the Automotive EMC Laboratory Recognition Program, supporting laboratory-to-laboratory comparison and ongoing site validation.
  • Compact cubic chassis — (HxWxD) 2.9″ × 3.1″ × 3.1″ (7.4 × 7.9 × 7.9 cm), 0.5 lbs (0.2 kg); the smallest comb generator in the lineup, easy to position on turntables, calibration jigs, or tripods.
  • Two interchangeable monopole antennas — 3-inch and 12-inch monopoles supplied for optimized radiation across the lower and upper portions of the 1 MHz to 1.5 GHz range.
  • Battery operation, 18+ hours per charge — internal 6 V / 1 Ah NiMH battery eliminates external power cables that could disturb the radiated signal, ensuring repeatable measurements.
  • Automatic low-battery shut-off — battery monitoring circuit shuts the unit down before output level degrades, preventing invalid reference data being collected with low-amplitude signals.
  • Stable, repeatable RF output — 20 ppm frequency stability and ±0.1 dB amplitude stability ensure that day-to-day baseline comparisons reflect real changes in the test setup, not drift in the source.
  • External LED indicators — battery low and power on indicators on the front panel confirm operating state at a glance during chamber walk-throughs.
  • Use as signal source for insertion loss — broadband output also serves as a stable reference for cable, attenuator, and filter insertion loss measurements, plus chamber-to-chamber 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.
