New from Schaffner is a sophisticated EMI measuring receiver with a frequency range from 9kHz to 18GHz.
New from Schaffner is a sophisticated EMI measuring receiver with a frequency range from 9kHz to 18GHz.
The new SMR 4518 receiver can be used stand alone, or form the core of a fully compliant CISPR-16 emission test system.
For example, the versatile instrument is capable of being used for highly sensitive selective voltage measurement, calibration of other measuring tools and attenuation measurement of shielding effectiveness.
When using an open area test site (OATS), fully anechoic chamber or GTEM cell, it can be integrated with all parts of the system for simple, accurate testing.
Frequency preselection and autoranging from 9kHz to 2.75GHz reduce overranging effects on pulse measurement, and in the 2.75 to 18GHz range, reduce high image frequency suppression also.
A very low noise floor and wide dynamic range deliver high sensitivity without an external pre-amplifier.
The instrument offers accuracy to the tenth harmonic, essential for testing products with today's high clock frequencies.
Ergonomically designed, the SMR 4518 offers a wide range of new operator-friendly functions and an easy-read 8.5inch TFT display.
Operational menus are easier to negotiate with fewer sub-menus and help files are available, in any language.
The instrument offers simultaneous display of various detectors, graph, bargraph and digital measured value.
The unit can be configured from the front panel for semi-automatic testing.
Powerful firmware allows numerous storage functions for device pre-setting, measured data, frequency spectrum and tables, transducer correction factors and direct data generation.
Only one input is required for the full frequency range.
Flexible software offers an oscilloscope mode and remote control.
The new input attenuator accepts input power up to three times higher than conventional receivers.
A pre-amplifier, behind preselection, increases sensitivity.
Signals from -26 to +137dBuV can be accurately measured.
The instrument meets MIL standards, above 150kHz, and makes compliant measurements to CISPR-16-1/99, VDE, EN, ETS, FCC, ANSI and VCCI standards.
