Description
The 1313-C30M Comb Generator is a conducted reference signal source for verification of conducted emissions measurementsystems. The Comb generator output has the harmonics of the fundamental frequency. It has two user selectable frequency stepsizes of 50 kHz and 250 kHz.
This Comb Generator simulates an EUT generating conducted EMI noise. The 1313-C series Comb Generators have a standard NEMA 15-P threeô€€€prong or CEE 7/7 schuko connector that can plug directly into any LISN with a compatible power socket. It can be attached to any othersocket type using a suitable adapter. The 1313-C30M has high impedance to the external line voltage, AC or DC up to 230V. This feature allows the Comb Generator to be used while the LISNs are connected to an external power source.
The 1313-C30M is powered by rechargeable internal Li-on batteries. The battery power eliminates the need for any external cabling. When fully charged,the battery allows continuous use of the Comb Generator for up to 18 hours. The Comb Generator and the charger are shipped with a custom storage/carrying case.
Application
The main application of the 1313-C30M Comb Generators is to quickly verify conducted emissions test setups. It is designed to plug directly into the EUT powersocket of an LISN. The conducted noise output level of the Comb Generators are close to or above the CISPR 22 limits. Typical output plots are shown on the next page.
Most EMI labs typically calibrate LISNs and other equipment (spectrum analyzers, cables, connectors, etc.) in the conducted emissions test setup at regular intervals. However, test equipment malfunctions may occur between any calibration interval and may go undetected until the next calibration. In the meantime, these malfunctions may produce erroneous test results. The time and resources lost due to these unforeseen errors can be avoided with the help of a Comb Generator. Using a Comb Generator, the test engineer will be able to quickly verify the conducted measurement system prior to each test to assure accurate test results.
Other possible applications of the 1313-C30M Comb Generator could include production evaluation of components, such as cable shields and filters.
