Turn your EMSCOPE receiver into a click meter for discontinuous conducted disturbances. The optional software license supports simultaneous line/neutral testing, four measurement frequencies, click statistics and automated PDF reports. Available for EMSCOPE, EMSCOPE-RX2, EMSCOPE-RX4 and EMSCOPE-RX4LZ2.

EMZER | CONDUCTED EMISSIONS & EMC DIAGNOSTICS
Measure discontinuous disturbances, review click statistics and document the result.
Add discontinuous conducted disturbance analysis to an existing EMSCOPE receiver or specify the license with a new system. The click meter evaluates intermittent disturbances from switching operations, helping laboratories and developers assess equipment against applicable CISPR 14-1 requirements.
| Four simultaneous frequency displays | 150 kHz, 500 kHz, 1.4 MHz and 30 MHz. |
|---|---|
| Line and neutral | Measure both paths simultaneously with the supported click meter configuration. |
| Peak and quasi-peak | Compare disturbances with selected CISPR 14-1 or user-defined limits. |
| Modal information | Use common/differential-mode information to help diagnose the noise source. |
| Automatic analysis | Review click rate, count, exceedances, duration groups and rule conditions. |
| PDF reporting | Combine plots, summary data and channel measurement-sequence flowcharts. |
Typical investigations include thermostatically controlled appliances, motor-driven equipment, relays, triacs and repetitive switching controls. Determine whether CISPR 14-1 applies to the product and configuration; the click meter does not replace correct product-standard and test-method selection.
| 1. Select host and LISN | Choose one of the four models below. EMSCOPE/RX4LZ2 include a single-phase LISN; RX2/RX4 require an external network. |
|---|---|
| 2. Activate the license | Open the instrument in a browser and select click meter mode. |
| 3. Configure the test | Set traces, observation duration, click-rate settings and applicable limits. |
| 4. Review results | Inspect four-frequency plots and statistics; investigate noise with modal information. |
| 5. Generate the report | Export plots, tables and sequence information to PDF. |
Four-frequency display. Example limits and traces illustrate the interface; choose the correct limits for the EUT.

It is a licensed EMSCOPE function. A compatible receiver and suitable LISN/test setup are required. Order it with a new system or for an existing instrument.
The current family technical sheet lists the click meter license for EMSCOPE, EMSCOPE-RX2, EMSCOPE-RX4 and EMSCOPE-RX4LZ2.
No. The four click frequencies are distinct from the receiver-channel count in the model comparison.
The four listed click frequencies are at or below 30 MHz. Wider receiver coverage is not required solely to reach those frequencies.
Yes, with correct product scope, EUT conditions, limits, network and laboratory procedure. The software supports measurement and reporting; it does not itself certify the product.
