Content is AI-generated. Verify critical details with manufacturer-provided resources.
What is the frequency range of the Anritsu S361E Cable and Antenna Analyzer?
The Anritsu S361E covers 2 MHz to 6 GHz for cable and antenna analysis. This extended frequency range makes it ideal for testing modern wireless infrastructure including 5G deployments, Wi-Fi 6, and CBRS band equipment. The analyzer provides precise measurements across the entire range with 1 kHz frequency resolution when RF immunity is set to low.
Can the S361E perform both reflection and transmission measurements?
Yes, the S361E performs comprehensive 1-port reflection measurements including return loss, VSWR, cable loss, and distance-to-fault analysis. With optional 2-port transmission measurement capability, it can also characterize insertion loss and gain through devices. The 2-port option provides high dynamic range of 95 dB typical from 2 MHz to 4 GHz, and 85 dB typical from 4 to 6 GHz.
How fast can the S361E complete measurements for field testing?
The S361E delivers exceptional sweep speed of 1.00 ms per data point for return loss measurements and 1.25 ms per data point for distance-to-fault measurements when RF immunity is set to low. This rapid measurement capability allows technicians to quickly troubleshoot antenna systems and identify faults in transmission lines without sacrificing accuracy.
What distance-to-fault resolution can I achieve with the S361E?
The DTF resolution is calculated as (1.5 x 10^8 x vp) divided by the frequency span, where vp is the cable's velocity propagation constant. With selectable data points from 137 to 2204 and multiple windowing options, you can optimize resolution based on your cable type and test requirements. The analyzer can display faults up to 1500 meters or 4921 feet with precise fault location accuracy.
Does the S361E include built-in bias tee capability?
Yes, the S361E features an internal bias tee option that supplies +12V to +32V at up to 450 mA for powering tower-mounted amplifiers and active antenna systems. The bias tee function requires the optional 2-port transmission measurement capability for the S361E model. Voltage is adjustable in 0.1V steps with current monitoring in low and high ranges.
What calibration methods does the S361E support for measurement accuracy?
The S361E supports multiple calibration methods including traditional OSL calibration for maximum directivity of 42 dB, and Anritsu's InstaCal one-step calibration providing 38 dB directivity. The analyzer also offers FlexCal for custom calibration scenarios. All calibration data includes temperature range information, and the system displays valid calibration temperature windows to ensure measurement integrity.
How many data points can the S361E capture in a single sweep?
The S361E offers five selectable data point settings: 137, 275, 551, 1102, and 2204 points per sweep. Higher data point counts provide finer frequency resolution and more detailed fault characterization in DTF mode, while lower counts enable faster sweep speeds for quick go/no-go testing. The data point selection is independent of frequency span, allowing flexible measurement optimization.
What is the return loss measurement range and accuracy of the S361E?
The S361E measures return loss from 0 dB to 60 dB with 0.01 dB resolution. After proper calibration using OSL or InstaCal methods, the corrected directivity specification ensures high accuracy across the frequency range. The analyzer provides separate uncertainty specifications for frequencies below 4 GHz and from 4 to 6 GHz, with magnitude and phase uncertainty curves documented for various return loss levels.
