width=\"1600\" height=\"447\" \/><\/a><figcaption class=\"wp-caption-text\">Keysight Pro XG7 SG6311A analog signal generator \u2013 front panel, two RF channels<\/figcaption><\/figure>\n<p class=\"lead\"><strong>The Keysight Pro XG7 analog signal generator (model SG6311A)<\/strong> produces metrology-grade RF signals from 9 kHz to 20 GHz, with 1 or 2 fully independent RF channels in a single 2U chassis, ultra-low phase noise and clean, calibrated output power up to +22 dBm.<\/p>\n<p>When source noise approaches the quantity you are trying to measure, the source eats into your measurement margin and masks the low-level response of the device under test (DUT). Keysight designed the Pro XG7 for exactly that situation: it reduces the phase noise, AM noise, broadband noise, harmonics and non-harmonics contributed by the source, so engineers see the true performance of the DUT in radar receiver tests, satellite payload work, high-speed converter characterisation and calibration labs.<\/p>\n<p>Pro XG7 is Keysight&#8217;s new product-line name; the front panel reads <strong>SG6311A PSG Signal Generator 9 kHz \u2013 20 GHz<\/strong>, so Pro XG7 and SG6311A refer to the same model. It refreshes the <a href=\"https:\/\/techmaster.com.vn\/en\/keysight-e8257d-psg-analog-signal-generator\/\">Keysight E8257D PSG analog signal generator<\/a> for applications up to 20 GHz and is distributed in Vietnam by Techmaster.<\/p>\n<h3>Hybrid YIG\/DDS architecture<\/h3>\n<p>Each channel combines a YIG-based RF synthesis path \u2014 the low-noise foundation for spectral purity \u2014 with direct digital synthesis (DDS) for very wide FM and PM deviation. Operating modes are selected in software according to whether purity, power or the type of test matters most, so engineers do not have to manage the underlying RF path. Each channel has its own conditioning and leveling and a step attenuator before the output.<\/p>\n<h3>Two independent channels, less rack space<\/h3>\n<p>For tests that need two independent RF stimuli \u2014 two-path measurements, direction finding, LO substitution with a test signal \u2014 one two-channel SG6311A replaces two separate signal generators, reducing system complexity and freeing rack space for other instruments.<\/p>\n<\/div>\n<div class=\"block\">\n<div class=\"eyebrow\">Specifications<\/div>\n<h2 id=\"sg6311a-specifications\">Keysight SG6311A Pro XG7 specifications<\/h2>\n<table>\n<caption>Key specifications<\/caption>\n<tbody>\n<tr>\n<th>Frequency range<\/th>\n<td>9 kHz \u2013 20 GHz<\/td>\n<\/tr>\n<tr>\n<th>RF channels<\/th>\n<td>1 or 2 fully independent channels<\/td>\n<\/tr>\n<tr>\n<th>Form factor<\/th>\n<td>2U, compact<\/td>\n<\/tr>\n<tr>\n<th>Output power<\/th>\n<td>Up to +22 dBm, clean and calibrated (+21 dBm at 10 GHz with option 1EB)<\/td>\n<\/tr>\n<tr>\n<th>Level accuracy<\/th>\n<td>\u00b10.3 dB at 10 GHz, 0 dBm<\/td>\n<\/tr>\n<tr>\n<th>Phase noise (10 GHz)<\/th>\n<td>\u2212135 dBc\/Hz (typical) at 10 kHz offset; \u2212169 dBc\/Hz (typical) at 10 MHz offset \u2014 option EP6<\/td>\n<\/tr>\n<tr>\n<th>AM noise<\/th>\n<td>\u2212150 dBc\/Hz (measured) at 10 GHz, 10 kHz offset \u2014 option EP6<\/td>\n<\/tr>\n<tr>\n<th>Broadband noise<\/th>\n<td>\u2212166 dBc\/Hz (typical) at 10 GHz, 30 MHz offset \u2014 option EP6<\/td>\n<\/tr>\n<tr>\n<th>Harmonics<\/th>\n<td>&lt; \u221255 dBc at 10 GHz<\/td>\n<\/tr>\n<tr>\n<th>Non-harmonics<\/th>\n<td>\u221282 dBc at 10 GHz<\/td>\n<\/tr>\n<tr>\n<th>Maximum FM deviation<\/th>\n<td>500 MHz (nominal) at 20 GHz \u2014 option UNT<\/td>\n<\/tr>\n<tr>\n<th>Modulation<\/th>\n<td>AM, FM, PM and pulse modulation<\/td>\n<\/tr>\n<tr>\n<th>RF architecture<\/th>\n<td>Hybrid YIG \/ DDS (direct digital synthesis), software-selected modes<\/td>\n<\/tr>\n<tr>\n<th>Reference<\/th>\n<td>10 MHz and 2.4 GHz reference in\/out<\/td>\n<\/tr>\n<tr>\n<th>Control<\/th>\n<td>SCPI over LAN and USB; rear-panel ports and default settings aligned with the PSG family<\/td>\n<\/tr>\n<tr>\n<th>Naming<\/th>\n<td>Keysight Pro XG7 Analog Signal Generator \u2014 model SG6311A (nameplate: SG6311A PSG)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"font-size:13px;color:#5b6b80\">Source: eBook \u201cThe Keysight Pro XG7 Analog Signal Generator\u201d, Keysight Technologies, 7126-1249.EN, 07\/10\/2026.
