DSA815 Spectrum Analyzer Employs Digital IF Technology

April 17, 2012. Rigol Technologies Inc. has introduced its DSA815 spectrum analyzer, featuring all-digital IF technology. The DSA815 covers a frequency range of 9 kHz to 1.5 GHz and features a compact design and easy-to-use interface.

The spectrum analyzer has a typical displayed average noise level (DANL) of -135 dBm, offset phase noise of -80 dBc/Hz at 10 kHz, and a total amplitude uncertainty of <1.5 dB, making it suitable for bench top or field applications in RF and wireless testing and production. The DSA815 spectrum analyzers include a range of standard functions, including AM/FM demodulation and a preamplifier, plus a variety of optional enhancements such as an EMI filter and quasi-peak detector kit and a 1.5-GHz tracking generator.

Rigol's digital IF design technology offers users the ability to measure smaller signals by enabling smaller bandwidth settings, thereby greatly reducing the displayed average noise level. With a minimum resolution bandwidth (RBW) of 100 Hz, Rigol's digital IF filter also facilitates the ability to distinguish between small signals close in frequency.

The DSA815 also features precise amplitude readings, virtually eliminating errors that occur when using traditional analog IF designs. Starting price is $1,295.
