The ANK-310 is a portable commercial EMC antenna kit covering 30 MHz to 1 GHz in a single rolling carrying case. This is the most-tested frequency band in commercial EMC — covering FCC Part 15, CISPR 22 / CISPR 32 / EN 55032 for ITE and multimedia, CISPR 11 / EN 55011 for industrial, CISPR 14 / EN 55014 for household appliances, and many other commercial radiated emissions standards. The kit bundles a collapsible biconical antenna, a compact log-periodic antenna, a low-noise preamplifier, a near-field probe set, a comb generator for site verification, and all required cables for pre-compliance or qualification-level testing at offsite or secondary locations.

Optional: AT-812 or AT-120 tripod (with or without ATC-812/ATC-120 tripod case)
3. Which EMC standards and test bands does the ANK-310 support?
• FCC Part 15 Subpart B (unintentional radiators) — the most common U.S. commercial EMC requirement
• FCC Part 15 Subpart C (intentional radiators up to 1 GHz)
• CISPR 22 / CISPR 32 / EN 55032 (IT equipment and multimedia)
• CISPR 11 / EN 55011 (industrial, scientific, medical)

• ANSI C63.4 U.S. methods for unintentional radiators
• VCCI (Japan), CNS (Taiwan), AS/NZS CISPR 32 (Australia/NZ) — all effectively identical to CISPR 32
• Site validation per CISPR 16-1-4 (normalized site attenuation)
4. Why does the ANK-310 use two antennas (biconical + log-periodic) instead of one?
Covering 30 MHz to 1 GHz with a single antenna means trading off gain, VSWR, or physical size. The ANK-310 uses two complementary antennas:
• Biconical (ABF-900A) works best at low VHF frequencies (30–300 MHz) where wavelengths are large (1–10 meters). Biconicals give near-omnidirectional response perpendicular to the antenna axis and reasonable gain across this octave
• Log-periodic (ALC-100) works best at UHF (300 MHz – 1 GHz) where wavelengths are short (0.3–1 m). Log-periodics are directional (higher gain), which increases sensitivity and reduces ambient pickup
This two-antenna approach matches the CISPR 16-1-1 and ANSI C63.4 recommendations used by virtually all commercial compliance labs. A 30-second antenna swap at 300 MHz is a standard part of every CISPR compliance sweep.
5. Why is the ABF-900A biconical antenna collapsible?
A standard biconical antenna at 30 MHz must be physically large — typically 1–1.5 meters tip-to-tip — to match the long wavelengths at the low end. For a portable kit intended for airline luggage transport, a rigid fixed-element biconical is impractical. The ABF-900A uses collapsible / folding elements that stow compactly inside the ANK-310 carrying case and deploy to full dimensions for measurement. Compliance performance is preserved because the element geometry when deployed matches a standard biconical, and each unit is calibrated in its deployed configuration with individual antenna factor data.
6. Why is the ALC-100 called a "compact" log-periodic?
Traditional log-periodic dipole arrays for 300 MHz–1 GHz are large (1.5–2 meters end-to-end) with many element pairs. The ALC-100 is engineered for portability with a physically smaller boom and element count while preserving the log-periodic pass band across 300 MHz – 1 GHz. It sacrifices some directivity vs. a full-sized lab log-periodic in exchange for fitting into a rolling case alongside the other kit components. Calibration data corrects the reduced size so measurement accuracy is preserved for pre-compliance and many qualification-level tests.
7. Why is the PAM-103 preamplifier included?
At commercial EMC test distances (typically 3 meters for pre-compliance or 10 meters for formal compliance), received signal levels can be very low — often only 10–30 dB above a typical receiver’s noise floor. Placing the PAM-103 low-noise preamplifier immediately after the antenna, before the long coaxial run to the receiver, boosts the signal before cable losses reduce it. This effectively lowers the system noise floor by 15–25 dB, making the difference between detecting a barely-compliant emission and missing it. The PAM-103 covers the full 30 MHz – 1 GHz band that both the biconical and log-periodic operate in.
8. What are the CGO-501 and CGO-505 comb generators, and which one do I get?
The ANK-310 ships with either the CGO-501 or the CGO-505 (customer option):
• CGO-501: 1 MHz – 1 GHz, 1 MHz step size. Denser comb gives more spectral coverage but lower amplitude per line
• CGO-505: 5 MHz – 1 GHz (usable to 1.5 GHz), 5 MHz step size. Wider spacing gives higher amplitude per line (energy concentrated in fewer tones), useful where signal-to-noise-floor is important
Both are battery-powered (rechargeable NiMH), have circular chassis for uniform omni-directional radiation in the horizontal plane, and operate 18+ hours per charge. Both serve the same purpose: quick verification of the entire measurement chain before or during a test session to catch bad cables, drifted calibration, or failing components before they corrupt an EUT measurement.
9. What is the PS-500 Near-Field Probe Set used for?
The PS-500 contains small H-field and E-field probes used to locate the source of EMI emissions on a circuit board, cable, enclosure, or harness. When the ANK-310 biconical or log-periodic detects an over-limit emission in the chamber, the PS-500 lets the engineer "sniff" the product up close to find exactly which trace, component, cable, seam, or vent is the radiator. Near-field probing is essential for EMI debug: far-field measurements tell you that the product is radiating, but near-field probes tell you where so you can apply corrective measures — filtering, shielding, layout changes, common-mode chokes, cable routing.
10. Who uses the ANK-310 and what real-world products does it test?
• Consumer electronics OEMs: PCs, laptops, tablets, game consoles, smart TVs, set-top boxes, audio/video receivers
• IT equipment vendors: servers, networking gear, storage arrays, switches, routers, power-over-Ethernet equipment
• Appliance manufacturers: kitchen appliances, laundry equipment, HVAC, power tools, personal care products
• Industrial automation: PLCs, motor drives, safety relays, sensors, factory-floor gateways
• Medical devices: patient monitors, diagnostic equipment, IEC 60601-1-2 pre-screening
• Lighting products: LED drivers, fixtures, smart lighting (above the CISPR 15 band or for 100+ MHz work)
• Wireless consumer products: Bluetooth, Wi-Fi, Zigbee, Z-Wave devices in their fundamental and harmonic bands
• EMC test labs: portable capability for customer-site work, temporary setups, or backup
• Consulting EMC engineers: offsite pre-compliance at client facilities
• Academic and research: university EMC labs, industry training courses
11. How does the ANK-310 compare with other Com-Power antenna kits?
• vs. ANK-140 (1–40 GHz): complementary upper-band kit for microwave/mmWave. ANK-310 is below 1 GHz; ANK-140 is above 1 GHz
• vs. ANK-318 (25 MHz – 18 GHz): ANK-318 extends the ANK-310 with an AH-118 horn antenna + PAM-118A preamp for 1–18 GHz coverage, and adds a second comb generator. ANK-318 = ANK-310 content + microwave capability
• vs. ANK-910L (9 kHz – 1 GHz, active loop): ANK-910L adds an AL-130R active loop for 9 kHz – 30 MHz H-field coverage at the low end but otherwise similar 30 MHz – 1 GHz capability
• vs. ANK-910M (9 kHz – 1 GHz, monopole): ANK-910M adds an AM-741R active monopole for 9 kHz – 30 MHz E-field (DO-160, MIL-STD)
For complete 9 kHz – 40 GHz coverage, pair ANK-140 + ANK-910L/M (overlap at 30 MHz – 1 GHz is intentional redundancy).
12. Is the ANK-310 sufficient for FCC and CE compliance filings?
The ANK-310 is sold primarily for pre-compliance and qualification-level testing — not necessarily for the final certification test that goes on the FCC/CE filing. For formal compliance testing, most products require ISO 17025 accredited testing at a 10-meter distance (CISPR) or 3-meter FAR (FCC). The ANK-310 enables labs to:
• Pre-compliance screening to find and fix problems before expensive formal testing
• Troubleshooting failures after a formal test reveals a marginal issue
• Qualification-level testing where the accreditation scheme allows portable equipment use
• Site validation and ongoing QA of a larger permanent chamber
That said, properly calibrated antenna kits with their individual NIST-traceable certificates are usable as-is in many commercial and industrial EMC scenarios where formal ISO 17025 accreditation isn’t the specific requirement.
13. What calibration and documentation comes with the ANK-310?
Each component is individually calibrated:
• Biconical antenna (ABF-900A) — calibrated antenna factor vs. frequency
• Log-periodic antenna (ALC-100) — calibrated antenna factor vs. frequency
• Preamplifier (PAM-103) — calibrated gain and noise figure
• Comb generator (CGO-501 or CGO-505) — calibrated output levels at each harmonic
• Near-field probes (PS-500) — calibration data where applicable
All calibrations are NIST-traceable per ANSI C63.5 and related methods. ISO 17025 accredited calibration is available on request when your organization’s compliance program requires an externally audited certificate. Annual recalibration is recommended for maintained traceability. Every item in the kit is also available individually for replacement.
14. What real-world scenarios benefit from the ANK-310?
• Scenario 1 — CISPR 32 pre-compliance: A small IoT product developer runs nightly scans with the ANK-310 in an unshielded conference room; finds an emission peak at 150 MHz, uses PS-500 probes to localize to a specific power supply harmonic, applies a common-mode choke
• Scenario 2 — On-site customer troubleshooting: A networking equipment vendor’s product fails at a customer site after installation; EMC consultant brings ANK-310 to the customer location, reproduces the issue with portable setup, identifies rack-level grounding problem
• Scenario 3 — Site validation: A 3-meter SAC chamber needs daily QA; a technician runs a CGO-501 scan with the ANK-310 setup at 30 MHz, 230 MHz, 500 MHz, and 900 MHz; 2 dB deviation from baseline triggers investigation before a $15,000 formal test is run
• Scenario 4 — Consultant pre-compliance service: An EMC consulting firm travels between client facilities with the ANK-310 as airline luggage; performs FCC/CE pre-compliance testing at each client before formal accredited testing
• Scenario 5 — University lab: An engineering program teaches EMC measurement techniques with the ANK-310 as a complete hands-on instrument set

16. When should engineers select the ANK-310 over other options?
Select the ANK-310 when any of the following applies:
• You need to perform FCC Part 15, CISPR 22/32, CISPR 11, CISPR 14, or similar commercial EMC pre-compliance or qualification-level radiated emissions testing
• Your products do not require testing above 1 GHz (or you have separate coverage for higher frequencies)
• You are a consultant, contract engineer, or mobile test technician needing portable commercial EMC capability at client sites
• You operate a lab that needs site validation QA equipment or backup capability beyond the main chamber
• You run academic EMC instruction or industry training requiring a complete, calibrated, hands-on antenna set
• You need airline-transportable equipment for customer demos, audits, or international work
Choose the ANK-318 if you also need 1–18 GHz (ANK-310 content plus horn antenna). Choose the ANK-140 for the 1–40 GHz microwave/mmWave range. Choose the ANK-910L or ANK-910M if you also need 9 kHz – 30 MHz (active loop H-field or monopole E-field).
