# Keysight E5061B-115 ENA Vector Network Analyzer, 100 kHz to 1.5 GHz, 50 Ω, Transmission/Reflection Test Set # Keysight E5061B-115 ENA Vector Network Analyzer, 100 kHz to 1.5 GHz, 50 Ω, Transmission/Reflection Test Set ## Key Features At A Glance - Vector network analyzer covering 5 Hz to 3 GHz across the series, with 50 Ω and 75 Ω system impedance options - Available as transmission/reflection or S-parameter test sets, plus LF-RF configurations with a built-in DC bias source - 10.4-inch multi-touch XGA (1024 x 768) LCD operated by hardkey, touchscreen, or mouse - Up to 4 independent measurement channels and 4 display windows, with 2 to 1601 points per trace - LAN (10/100/1000BaseT) and USB standard; GPIB (IEEE-488) and 24-bit handler I/O available as options - Type-N test ports with multiple calibration types including full 2-port, enhanced response, and one-port - Built-in VBA automation with SCPI and COM control for automated and ATE measurement systems - System dynamic range up to 130 dB at 10 Hz IF bandwidth The Keysight E5061B is an ENA-series vector network analyzer that characterizes the magnitude and phase of the reflection and transmission (S-parameter) response of components and networks. It spans 100 kHz to 1.5 GHz or 3 GHz in its RF network analyzer configurations, and from 5 Hz up to 500 MHz, 1.5 GHz, or 3 GHz in its LF-RF configurations, addressing both low-frequency and RF measurement needs in a single bench instrument. As a vector network analyzer, the E5061B measures S-parameters and converts them into related quantities including reflection and transmission impedance, reflection and transmission admittance, and 1/S. Beyond standard S-parameter work, the LF-RF configurations add gain-phase measurement, and option-based capabilities extend the instrument to impedance measurement and equivalent-circuit analysis (Option 005), wireless power transfer circuit evaluation with 2D/3D simulation (Option 006), and fault location with time-domain transformation (Option 010). ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Because instruments are held on our own shelves, we can confirm condition and configuration before an order goes out the door. ## Brand Heritage Keysight Technologies traces its test-and-measurement heritage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was then established as Keysight Technologies in 2014, the brand under which this analyzer is produced today. ## Compare Other Models in This Series The E5061B ENA vector network analyzer is offered in a range of test-set configurations that share a common platform but differ in frequency coverage, system impedance, and measurement capability. The RF network analyzer options provide 50 Ω or 75 Ω system impedance with coverage to 1.5 GHz or 3 GHz, available as transmission/reflection or S-parameter test sets. A separate group of LF-RF options (3L3, 3L4, and 3L5) extends measurement coverage down to 5 Hz and adds a built-in DC bias source and gain-phase measurement, reaching 500 MHz, 1.5 GHz, or 3 GHz at the upper end depending on the option chosen. Each new model linked below is its own dedicated product page with condition-matched pricing. Select the configuration whose frequency range, system impedance, and measurement set matches your application, and review its individual page for the specifications and pricing that apply to that new unit. The clearest differences across the family are frequency coverage and system impedance — the 1.5 GHz versus 3 GHz tiers, 50 Ω versus 75 Ω system impedance, and the LF-RF options that begin at 5 Hz. Measurement capability also varies by configuration: transmission/reflection test sets (Options 115, 135, 117, 137) measure S11, S21, and absolute power, while S-parameter test sets (Options 215, 235, 237) add S12 and S22. The LF-RF options (3L3, 3L4, 3L5) provide the full S-parameter set along with T/R, T, R, and absolute measurements, plus the DC bias source and gain-phase ports. See the comparison table for the per-option frequency ranges, system impedance, test-set type, and measurement parameters.
