The ESA family is designed to deliver proven and guaranteed performance with the flexibility to select the right level of functionality for a given test need, and is offered in three express configurations — Basic, Standard, and Communications Test — to match the instrument to the application. The datasheet positions the ESA Series for general-purpose RF and microwave spectrum measurement, with the E4407B specifically covering frequencies through K-band. Custom configuration with the low frequency extension (Option UKB) extends the lower frequency limit to 100 Hz, and external mixing (Option AYZ) extends coverage from 18 GHz up to 325 GHz, enabling measurements well into the millimeter-wave range for harmonic mixing applications. ValueTronics has specialized in test and measurement equipment since 1992. Every {{CONDITION}} ESA-E Series analyzer in our inventory is processed through our 20,000 square foot facility at 1675 Cambridge Drive in Elgin, Illinois, where instruments are catalogued, inspected, and verified before shipping. Working through ValueTronics — rather than a drop-shipper or pass-through broker — means the analyzer you order has been physically handled and confirmed by our team prior to leaving the warehouse. ## Brand Heritage Agilent Technologies was spun off from Hewlett-Packard in 1999 as the dedicated test and measurement company; in 2014, Agilent's electronic measurement business was further separated to form Keysight Technologies, which is the current corporate home for the ESA Series product line and its associated support, calibration, and documentation infrastructure. ## Compare Other Models in This Series The ESA-E Series is offered in five frequency models — E4402B (3 GHz), E4404B (6.7 GHz), E4405B (13.2 GHz), E4407B (26.5 GHz), and the basic E4411B/E4403B/E4408B variants — covering general-purpose spectrum measurement from 9 kHz through K-band. The datasheet groups these into three express configurations: Basic Analyzer (Option BAS), Standard Analyzer (Option STD), and Communications Test Analyzer (Option COM), with custom configuration available to add narrow RBW, precision frequency reference, tracking generator, EMI bandwidths, and external mixing capabilities. Within the standard and communications test configurations, the primary differentiation across models is upper frequency limit. The E4407B at 26.5 GHz provides the widest coverage of any single ESA-E model and is the only member that supports the 18 GHz to 325 GHz external mixing extension through Option AYZ. All standard/COM models share the same RBW range, amplitude range, trace memory, and connectivity baseline. Each pre-owned ESA-E model is listed as its own product page with condition-matched pricing. The links below take you to the specific frequency variant for direct comparison of inventory and current availability. The E4407B is the 26.5 GHz model in the standard and communications test analyzer configurations of the ESA-E Series. It is the only ESA-E model where Option AYZ external mixing extends the usable frequency range from 18 GHz to 325 GHz, making it the appropriate choice in the family when measurement requirements approach or exceed K-band, or when harmonic mixing into the millimeter-wave region is required. The ESA-E Series models differ primarily in upper frequency coverage. The E4402B covers to 3 GHz, E4404B to 6.7 GHz, E4405B to 13.2 GHz, and E4407B to 26.5 GHz, with all four sharing the same core architecture, RBW range, trace memory, sweep capabilities, and rear-panel I/O. Within the basic analyzer line, the E4411B covers to 1.5 GHz, the E4403B to 3 GHz, and the E4408B to 26.5 GHz. Specific amplitude and phase noise performance varies by frequency band — for example, displayed average noise level on the E4407B is typical -132 dBm at 22 to 26.5 GHz versus typical -140 dBm at 1.5 to 2 GHz — reflecting the higher mixing harmonics required to reach upper-band coverage. The comparison table that follows shows the specific frequency, configuration, and option differences across the family at a glance.
