DESCRIPTION
The Model 4402B is an ultra-pure sinewave,
stable amplitude oscillator designed to meet the needs of today’s high precision
16 to 18 bit A/D converter testing, and audio test and measurement technology.
Covering the frequency
range from 1Hz to 110kHz, with precise 3 digit frequency tuning, the 4402B
produces a virtually “distortion-free” (<0.0005%) sinewave for measuring A/D
converter accuracy, audio preamplifier and power amplifier harmonic distortion.
With its exceptionally flat response (0.02dB), the 4402B eliminates the need
to constantly monitor voltage levels, during frequency response testing.
OUTPUT
The 4402B
provides a 7Vrms sinewave output (balanced output, 14Vrms end-to-end), 3.5Vrms
into 50 ohms, and has no loss in performance when loaded with a linear 50
ohm load. A 3-position, push-button attenuator calibrated in 20dB steps, along
with a 30dB vernier, provides a total dynamic range of 90dB.
Simultaneous fixed
and quadrature (90º) outputs are provided. Each output is 7Vrms with a 600
ohm source impedance.
The 4402B is the
perfect addition to your present test and/or precision measurement set-up.
