Amplifier Research SM400K Complex Signal Analyzer DC-400kHz

The SM400K is a high performance handheld analyzer designed for measuring complex or pulsed electric and magnetic fields up to 400kHz, and broadband measurements up to 40GHz.

By selecting the appropriate sensor heads for the desired field types, frequency ranges, and power levels, a single meter with removable sensor heads can replace multiple fixed-head dedicated field measuring meters. Refer to the SH-series sensor head specification sheets for the available sensor heads.

The Real Time operating mode function provides a quick view of the main indexes and the trend of the field in the time and frequency domains through repeated acquisitions generating up to 65,536 samples. These acquisitions may be triggered manually or automatically.

The Monitoring operation mode function allows for the signals to be recorded to the non-volatile internal memory of the instrument from the sensor head. This allows the user to download the data to the PC and extract the relevant information such as signal amplitude/frequency and indexes acquired during the monitoring period. This feature, together with the instrument’s battery autonomy allow it to perform monitoring tasks with a span of 1kHz bandwidth for over 24 hours.

ARwavewARe Software

The ARwavewARe software application allows the user to analyze the recorded data in both time domain and frequency domain and provides real time processing and post processing capabilities.

During the real-time processing, the oscilloscope function captures the signal in automatic or manual mode using a special trigger. The signals displayed can then be controlled or managed by way of a pan/zoom control.

The measurements are more easily interpreted by the use of a marker function which simultaneously provides the value of the level and frequency/time.

The same concept applies in the frequency domain where the user can insert the various masks of the curves required by the safety standards for the purpose of comparison.

The ARwavewARe software allows the selection of four indexes: the weighted peak WP10, the index IB50, II98 and IRSS.

The readings always reported include: The average RMS, the RMS average normalized with respect to the frequency limit predominant (IRMS), the maximum and minimum value, the frequency with the highest spectral content. (Fmax).

A special command allows the user to filter spectral content in the frequency domain, eliminating those that have a value of less than 10%, which is indicated below the red threshold line. This function is specifically requested by CEl EN 50500.

All information displayed can be exported either as images or as tabulated data. The ARwavewARe software application can be installed on systems running Microsoft Windows XP, Windows Vista, Windows 7 and Windows 8, both 32 and 64 bit.
