The Workhorse Radiated Reference for Commercial EMC Labs
Broadband radiated EMC reference for fast pre-test validation of OATS, SAC, and FAC test sites between formal NSA calibrations — the most widely used step size for daily site checks in FCC Part 15 and CISPR 32 compliance labs.
Radiated Reference Signal Source for OATS, SAC, and FAC
Broadband EMC reference source for quick verification of radiated emissions test sites between formal calibrations — catches failing preamps, broken cables, and oxidized connectors before they produce months of invalid compliance data.
Wide Frequency Range: 5 MHz to 1.5 GHz
Covers the full commercial radiated test band used by FCC Part 15, CISPR 32 / EN 55032, and most commercial EMC standards in a single instrument.
Fixed 5 MHz Step Size — General-Purpose Verification
Harmonics every 5 MHz keep the output usable across the full 1.5 GHz span while reducing energy density per MHz — individual spectral lines 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 for both horizontal and vertical polarization checks.
Two Interchangeable Monopole Antennas (5-inch and 12-inch)
Both monopoles are supplied — use the 12-inch for the lower portion of the band and the 5-inch for optimized radiation toward the upper end 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. Charger output: 6 VDC (unregulated) at 500 mA.
Automatic Low-Battery Shut-Off
Battery monitoring circuit shuts the unit down before output level degrades — protects baseline data integrity by preventing reference measurements from being collected at reduced amplitude.
Stable, Repeatable RF Output
20 ppm frequency stability, ±0.1 dB amplitude stability, and less than 1 dB time stability over 12 months — ensures 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 LEDs confirm operating status at a glance during chamber walk-throughs — no need to interrupt a test session to verify the unit is active.
Insertion Loss and Inter-Site Comparison Source
Broadband output also serves as a stable reference for cable, attenuator, and filter insertion loss measurements, inter-site comparisons, and shielding effectiveness tests.
NIST-Traceable Calibration
Individually NIST-traceable calibrated; calibration data and certificate ship with each unit. ISO 17025 accredited calibration available on request for laboratories requiring full accreditation chain documentation.
Three-Year Standard Warranty
Three-year standard warranty backed by manufacturer support.
