Switch to the Keysight EXA Signal Analyzer for Better Noise Measurements

Three reasons why the Keysight EXA signal analyzer provides easier analysis of signals otherwise hidden in signal noise

Improved sensitivity

The EXA’s narrow resolution bandwidth settings, variable attenuation, an external USB smart preamplifier, noise floor extension and fast sweeping provide improved sensitivity.

Improved sweep rates

The EXA offers sweep rates up to 50 times faster than traditional methods without compromising measurement accuracy.

Improved noise figure uncertainty

The EXA’s external SNS Series smart noise source, an external USB smart preamplifier and an internal or web based noise figure calculator result in improved noise figure uncertainty.

Noise, a characteristic of all electronic circuits, can cause random disturbance of a useful information signal in a communication channel, and adversely affect your measurement. So making accurate measurements in noise, within time and budget constraints, is vital. The Keysight Technologies, Inc. N9010B EXA signal analyzer offers a streamlined 10.6 inch multi-touch user interface with flexible measurement displays, as well as industry- leading performance in sensitivity, fast spurious search, and noise figure uncertainty. Address your particular noise measurement needs with the largest suite of measurement applications that capture measurement expertise and deliver repeatable results.

Make faster and easier noise measurements, with a single tool

The EXA’s narrow resolution bandwidth settings, variable attenuation, an external USB preamplifier, noise floor extension and fast sweeping provide improved sensitivity.

The Keysight EXA offers internal preamplifier options to help boost low level signals near noise. A smart external preamplifier can be used to further increase instrument sensitivity, so you can see signals that were not visible before. Only Keysight offers noise floor extension technology – that lowers the analyzer’s noise floor (by up to 10 dB) with a single button push.

The EXA offers sweep rates up to 50 times faster than traditional methods without compromising measurement accuracy.

The fast sweep feature allows up to 50 times faster sweep speeds with low RBW, providing the fastest and most efficient way to look for low level spurs.

The EXA’s external SNS Series smart noise source, an external USB smart preamplifier and an internal or web based noise figure calculator result in improved noise figure uncertainty and lower design cost.

The Keysight EXA offers the best noise figure measurement uncertainty and the best ease of use when making noise figure measurements. The SNS Series smart noise source automatically transfers ENR data to the EXA, and offers the industry’s lowest overall ENR uncertainty. Additionally, the external USB smart preamplifier further improves the overall noise figure measurement uncertainty and ease of use. A time-saving feature, internal calibration with the noise floor extension (NFE) option, offers very good measurement uncertainty without the need to perform the Y-factor second stage calibration step.
