Anritsu S331E Spec Sheet
Anritsu Site Master S3xxE User Manual
Content is AI-generated. Verify critical details with manufacturer-provided resources.
What is the frequency range of the Anritsu S331E Site Master Cable and Antenna Analyzer?
The S331E covers 2 MHz to 4.0 GHz for Cable and Antenna Analysis with measurements including Return Loss, VSWR, Cable Loss, Distance-to-Fault, and 1-Port Phase. The frequency accuracy is plus or minus 2.5 ppm at 25 degrees Celsius, with resolution of 1 kHz in RF immunity low mode and 100 kHz in RF immunity high mode. It provides excellent interference immunity with 0 dBm tolerance within plus or minus 10 kHz of the carrier frequency, making it suitable for testing in live RF environments.
What directivity and measurement accuracy does the S331E achieve?
The S331E achieves 42 dB directivity with OSL (Open-Short-Load) calibration and 38 dB with InstaCal calibration. The high directivity ensures accurate measurements of Return Loss from 0 to 60 dB and VSWR from 1:1 to 65:1 with 0.01 resolution. The analyzer features fast measurement speed of 1.00 ms per data point for Return Loss and 1.25 ms per data point for Distance-to-Fault in RF immunity low mode.
How many data points can the S331E collect for DTF measurements?
The S331E offers selectable data point settings of 137, 275, 551, 1102, or 2204 points per trace. The fault resolution in meters is calculated as (1.5 x 10 to the 8th x vp) / F, where vp is the velocity propagation constant and F is the frequency span. The horizontal range extends up to a maximum of 1500 meters (4921 feet), providing detailed resolution for accurately locating cable faults and verifying installations.
Does the S331E support 2-port transmission measurements?
Yes, with Option 21, the S331E supports 2-port transmission measurements from 2 MHz to 4 GHz with high and low output power settings. The high dynamic range mode achieves 80 dB from 2 MHz to 4 GHz (95 dB typical). This capability is essential for measuring insertion loss of filters, amplifiers, and complete antenna systems. The analyzer also supports 50 ohm and 75 ohm impedance settings.
What display and user interface features does the S331E offer?
The S331E features an 8.4 inch daylight viewable touchscreen with single or dual measurement display capability and independent markers on each display. This allows simultaneous viewing of different measurement types such as Return Loss and Distance-to-Fault side by side. The touchscreen keyboard and Quick Name Matrix simplify data management, and the instrument stores up to 2000 traces internally.
Can the S331E be used for automated or remote testing applications?
Yes, the S331E supports both Web Remote Control and programmable remote control via SCPI commands through Ethernet (Option 413) or USB connections. This enables automation of repetitive or operator-intensive tasks, increasing throughput in production or lab environments. The Ethernet connectivity option provides 10 Mbps data transfer in static or DHCP mode, and the easyTest Tools application can further streamline common measurement workflows.
What battery life does the S331E provide for field testing?
The S331E provides 4.5 hours of battery operation time on its 12 VDC Li-ion battery, allowing extended field testing without AC power. The instrument reaches full operating specifications in less than 5 minutes of warm-up time. At only 273 mm x 199 mm x 91 mm and 2.71 kg (6.0 lb), its compact size and lightweight design make it highly portable for tower climbs and site visits.
What calibration options are available on the S331E?
The S331E supports three calibration methods: Standard OSL (Open-Short-Load) calibration for maximum accuracy at 42 dB directivity, InstaCal for quick single-connection calibration at 38 dB directivity, and FlexCal for flexible calibration setups. The instrument can display the valid calibration temperature range and store calibration data alongside measurement files. The recommended calibration cycle is 12 months for maintaining specified performance.
