The EMI Receiver System from Lisun Electronics Co., Ltd. is a laboratory-grade instrument designed for electromagnetic interference testing, available in two models: KH3961 (9 kHz to 30 MHz) and KH3962 (9 kHz to 300 MHz). It measures signal amplitude from 20 dBµV to 140 dBµV using peak, quasi-peak, and average detection methods. The system connects to a PC via USB and runs on Windows 7 and 8, generating standardized test reports compliant with CISPR 16-1, GB 17743, FCC, and EN 55022.
The KH3962 model features a fully enclosed metal housing with high electromagnetic shielding to prevent internal self-interference, a known issue in older EMI receivers. Frequency resolution is 30 Hz below 150 kHz and 1 kHz above, with a frequency stability of ±1×10⁻⁶. Sweep bandwidth options include 200 Hz, 9 kHz, and 120 kHz, matching standard EMC test requirements. No internal calibration source is mentioned; external reference signals must be provided.
This system is purchased by electronics manufacturers, compliance testing labs, and product certification agencies in North America, Europe, and Southeast Asia for pre-compliance and diagnostic testing. Users typically operate it in controlled lab environments. The unit requires a Windows-based PC and licensed software. Packaging includes a protective case and USB cable. Lead time, warranty, and calibration certificates are not stated and must be confirmed with the supplier.

Before ordering, confirm whether the EMI receiver includes the required software license and if it supports your Windows version. Request a list of supported test standards and sample reports to verify compliance. Ensure the USB interface is compatible with your lab computers and that the software can export data in your required format.
Lead time, Incoterms, and payment terms are not disclosed. Buyers should confirm whether the unit is shipped FOB Shanghai or EXW, and if shipping includes insurance for sensitive electronics. Confirm if the unit is pre-calibrated and whether a calibration certificate is provided. Payment is typically via T/T, but L/C may be negotiable for large orders.
Upon receipt, verify the unit’s serial number matches the documentation. Test the USB connection and software launch before installation. Perform a basic signal sweep using a known reference source to validate accuracy. Retain all packaging and documentation for warranty claims. Calibration should be scheduled annually by an accredited lab if used for compliance testing.
