 The {{Title|General Radio 1900-A Wave Analyzer}} was introduced in {{Catalog R}} and remained available through {{Catalog 1973}}.
-The Type 1900-A Wave Analyzer is designed to measure and analyze electrical signals between 20 Hz and 54 KHz at bandwidths as narrow as 3 Hz.  When coupled with the recorder Type [[1521-B]] a permanent record of the spectrum of interest is produced. The 1900-A has a built in tracking generator whose frequency is synchronized with the analyzer frequency. This generator can be used as a source for bridges or networks, the output can be measured using its high selectivity to reduce noise and harmonics. Applications include analyzing filters and frequency response of amplifiers or networks.

-The 1900-A is complex instrument but major components are housed in their respective shielded enclosures.  These subassemblies are connected using RCA and Jones type connectors simplifying service.  The 1900-A and the [[1521-B]] combination make up the Type [[1910-A]] Recording Wave Analyzer.
