1. Introduction  
 These Technical Requirements are an integral part of the Procurement 
Documentation and constitutes the complete set of r equirements on the basis of which 
the Technical Proposal is to be prepared by each tenderer. 
 The requirements set forth shall be considered min imum and mandatory. In this 
regard, any submitted offer that deviates from the provisions of the Technical 
Requirements will only be considered to the extent that the Technical Proposal ensures a 
qualitative level superior to the minimum requireme nts specified herein. Any offer 
containing product characteristics inferior to thos e stipulated in these Technical 
Requirements will be deemed non-compliant and will be rejected. 
 The subject matter of the procurement procedure is  the supply of one portable 
spectrum analyzer together with all necessary accessories. 
2. Purpose of procurement 
 The purpose of procuring the portable spectrum ana lyzer is to modernize the 
National Spectrum Monitoring System operated by the  National Regulatory Agency for 
Communications (ARCOM), by replacing existing porta ble spectrum analyzers that are 
outdated and have a high degree of wear. 
 The portable spectrum analyzer is intended to be u sed in the process of verifying 
and measuring the technical emission parameters of radio communication stations, 
particularly base stations within mobile cellular communication networks, including 5G NR.
