TECHNICAL DESCRIPTION:

Circuit Information
The input circuit consists of a shielded transformer. This is followed by an audio-amplifier, and the indicating meter. A thermal relay shorts out the meter for 20 seconds after power is applied to the built-in regulated supply to avoid damage due to surge voltages.
Power Supply
115 volts ±10%, ac, 50 to 60 cycles per second, single-phase, 15 watts ;Frequency Range:
30 to 15,000 cps
Audio Level Indicating Range
As a bridging type instrument: -20 to +20 db with a total range including meter scale of -40 to +23 db
As a terminating type instrument: -40 to +20 db with a total range including meter scale of -60 to +23 db
Meter Scale
-20 to +3 dbm
Reference Level
0 VU (1 mw into 600 ohms)
Input Impedance
Terminating Connection: 600 ohms
Bridging Connection: 12,500 ohms
Frequency Response
±0.1 db from 200 to 10,000 cps
±0.5 db from 30 to 15,000 cps
Accuracy
Overall: ±5%
From-15 to +10 db from 200 to 10,000 cps. ±1%
Temperature Range
-15° C. (+5° F.) to +55°C. (+131° F.)
Humidity Range
Up to 90%
Major Unit
TS429A/U 5 1/4" x 19" x 11"; 20 lbs
