Applications

The MS2713E provides essential diagnostics for diverse wireless environments:

Wireless Network Deployment: Installation and commissioning of 2G, 3G, 4G, and LTE base stations.
Interference Hunting: Identifying and locating external radio frequency (RF) interference.
Spectrum Monitoring: Monitoring signal power, occupancy, and spectral purity.
LMR/Public Safety: Testing Land Mobile Radio systems for compliance and coverage.
Signal Analysis: Analyzing signal quality, occupied bandwidth, and channel power.

Key Features Explained

Advanced Measurement Suite: Includes channel power, occupied bandwidth, adjacent channel power ratio (ACPR), and field strength measurements.
GPS Integration: Built-in GPS allows for location-tagged measurements, which is critical for mapping interference sources.
Rugged Design: Field-proven design that can withstand the physical rigors of cell tower climbs and harsh outdoor environments.
Ease of Use: An intuitive menu structure and dedicated buttons for common measurements speed up field analysis.

Usage Instructions

Calibration: Always perform a “Cal” (if using cable/antenna analysis options) or ensure the unit is warmed up for at least 5–10 minutes for optimal frequency stability.
Frequency Setup: Set the Center Frequency and Span to capture the specific band or channel you are interested in.
Reference Level: Adjust the Ref Level to ensure the signal is clearly visible on the screen without saturating the input stages of the analyzer.
Resolution Bandwidth (RBW): Use a narrower RBW to better resolve closely spaced signals or a wider RBW for faster sweep times.
Data Export: Use the USB port or Ethernet connection to export trace data to Anritsu’s Master Software Tools (MST) for post-processing and report generation.

Frequently Asked Questions (Q&A)

Q: Can the MS2713E perform distance-to-fault (DTF) measurements?

A: The MS2713E is primarily a spectrum analyzer. While it has optional features, true DTF measurements usually require the Site Master (S331 series) functionality. Check if your specific unit has the cable and antenna analyzer option enabled.

Q: How often should the unit be factory calibrated?

A: Anritsu recommends annual factory calibration to ensure measurements remain within specified accuracy limits for regulatory and technical compliance.

Q: What do I do if I see a signal I don’t recognize?

A: Use the Spectrogram view mode to monitor signals over time; this helps distinguish between constant carriers, intermittent noise, and transient interference.
