Vector Voltmeter (Option 15)
A phased array system relies on phase matched cables for nominal performance. For this class of application, the LMR Master offers this special software
mode to simplify phase matching cables at a single frequency. The similarity between the popular vector voltmeter and this software mode ensures
minimal training is required to phase match cables. Operation is as simple as configuring the display for absolute or relative measurements. The
easy-to-read large fonts show either reflection or transmission measurements using impedance, magnitude, or VSWR readouts. For instrument landing
system (ILS) or VHF Omni-directional Range (VOR) applications, a table view improves operator efficiency when phase matching up to twelve cables. The
S412E solution is superior because the signal source is included internally, precluding the need for an external signal generator.

Distance Domain
Distance-to-Fault Analysis is a powerful field test tool to analyze cables for faults, including minor discontinuities that may occur due to a loose
connection, corrosion, or other aging effects. By using Frequency Domain Reflectometry (FDR), the VNA’s DTF mode exploits a user-specified band of full
power operational frequencies (instead of DC pulses from TDR approaches) to more precisely identify discontinuities. The VNA converts S-parameters
from frequency domain into distance domain on the horizontal display axis, using a mathematical computation called Inverse Fourier Transform.
Connect a reflection at the opposite end of the cable and the discontinuities appear versus distance to reveal any potential maintenance issues. When
access to both ends of the cable is convenient, a similar distance domain analysis is available on transmission measurements.
Distance Domain will improve your productivity with displays of the cable in terms of discontinuities versus distance. This readout can then be compared
against previous measurements (from stored data) to determine whether any degradations have occurred since installation (or the last maintenance
activity). More importantly, you will know precisely where to go to fix the problem and minimize or prevent downtime of the system.
