The T346 is a compact 4-channel, 32 MHz waveform generator. It incorporates four DDS waveform synthesizers that may be used independently or synchronously to produce coherent signals. Waveforms include sine, triangle, sawtooth, Gaussian noise, and precision pulse/PWM outputs. User-loaded arbitrary waveforms may be generated.

Four additional waveform generators are provided internally as modulation/summing sources. Channel-channel modulation capability allows generation of sweeps, chirps, I/Q and constellations, and calibrated jitter, and simulation of a wide range of radar, communications, power, encoders, and electro-mechanical systems.
The T34x family of generators includes the T340 and T344.
The T346 can be an ideal system replacement for the HP models 3314A, 3325A, 3325B, 3326A, 8111A, 8116A, 8165A, 8175A,
and 8904A. |
