The Precision Integrating Sound Level Meter Type 2236A
is a Type 1 instrument, designed to meet stringent standards in environmental- and occupational-noise measurement.
Measurements are displayed on a large (4 lines, 16 characters/line) LCD screen. The SPL (RMS) is continuously monitored on a quasi-analogue display. The digital output allows interfacing with personal computers and printers, for further data processing/presentation and printing.
The linearly-weighted AC output allows for a direct calibrated recording (on Digital Audio Tape, for example), enabling later analysis.
A unique feature of the 2236A is that RMS and Peak detection occurs in parallel.
