VNA Master™ User Guide Model MS20xxC Vector Network Analyzer with Spectrum Analyzer : General Information : Instrument Description
 
Instrument Description
The Anritsu VNA Master instruments are portable handheld vector network analyzers (VNAs) featuring precise performance and essential RF capabilities. These VNA Master instruments are designed to conduct accurate vector‑corrected 1‑port magnitude, phase, and fault location measurements and 2‑port magnitude, phase, and group delay measurements from 5 kHz to 20 GHz. The MS203xC models add Spectrum Analyzer capabilities that provide quick and accurate measurement results for monitoring, measuring, and analyzing signal environments. The Spectrum Analyzer offers broad spectrum analysis with frequency coverage to 20 GHz, impressive dynamic range, and excellent phase noise performance. Standard measurements include field strength, occupied bandwidth (OBW), channel power, adjacent channel power ratio (ACPR), and carrier to interference (C/I) ratio.
Trace Storage
Time and date stamping of measurement data is automatic. The internal memory provides for the storage and recall of more than 4000 measurement setups and traces. External storage can be used for bulk measurement storage. Measurements and setups can be stored in a USB flash drive or transferred to a PC by using the included USB cable. Use Line Sweep Tools (LST) for certain VNA measurements and Master Software Tools (MST) for spectral analysis measurements.
Note 
Not all after‑market USB drives are compatible with the VNA Master. Many drives come with a second partition that contains proprietary firmware. This partition must be removed. Only one partition is allowed. Refer to the individual manufacturer for instructions on how to remove it. You may also try reformatting a drive that contains a single partition using FAT32 format.
