EMSCOPE EMI Receiver with LISN

EMSCOPE, 9kHz - 110MHz, 2 channel Receiver/LISN

Measure line and neutral conducted emissions with a two-channel FFT EMI receiver and built-in 16 A single-phase LISN. EMSCOPE supports common-mode and differential-mode analysis for filter development, with 30 MHz base coverage and an available 110 MHz upgrade. Add the optional CISPR 14-1 click meter license for discontinuous disturbance testing.

EMSCOPE EMI Receiver with Integrated LISN

An integrated single-phase conducted-emissions test system.

EMZER EMSCOPE two-channel EMI receiver with integrated single-phase LISN

EMSCOPE combines two receiver channels, transient limiters and a single-phase LISN. Specify socket configuration when ordering.

Conducted EMI testing and filter development

Test single-phase equipment, evaluate line and neutral noise, and identify whether common-mode or differential-mode emissions dominate. The integrated LISN provides a compact bench setup for development and verification within the selected socket’s electrical ratings.

Two-channel measurement	Observe line and neutral with peak, quasi-peak and average detectors.
Modal diagnosis	Separate common-mode and differential-mode contributions to guide filter design.
Integrated single-phase LISN	Reduce separate bench components for EUTs within the network’s ratings.
Browser operation	Use the embedded application through the optical-fiber connection; no separate measurement-software installation is required.

Measurement setup

1. Connect the EUT	Use the internal single-phase LISN where fitted and suitable, or a correctly rated external network.
2. Connect the receiver	Connect measurement outputs to the appropriate RF inputs using suitable coaxial cables.
3. Select the measurement	Choose EMI or modal mode, span, detectors, bandwidth, dwell time and the applicable limit line.
4. Compare and document	Review traces, identify dominant noise modes and export results. Add the click meter license for discontinuous disturbance testing.

Practical questions

Can I connect any 16 A appliance?

Check the fitted socket, voltage, current, grounding and test requirements. The 16 A rating is socket dependent; specify the appropriate North American outlet.

Is the click meter included?

No. It is an optional license for discontinuous disturbance testing. Normal EMI and modal software is included.

Do I need to install measurement software?

The application is embedded in the instrument and accessed in a browser. A browser-equipped device and suitable optical/network connection are still required.

Is 110 MHz standard?

The model table lists 30 MHz base coverage and UPGR-110 as an available upgrade. Specify the required coverage in the quotation.
