Tektronix 390AD. PROGRAMMABLE WAVEFORM DIGITIZER
The Tektronix 390AD is a Programmable Digitizers.
The 390AD has a built in self calibration and a self test feature that is automatically employed at power on and can be activated during operation by the user.
True dual channel 30 MHz sampling rate (60 MHz in single channel mode)
Cursor-based measurements, sample rating switch
Auto Cal (Self-Calibration)
2048 word memory per channel (4096 single channel mode)
direct plotter output capability.
The following applications are via extracting information from signals containing components from DC to 15 MHz : Ultrasonic/stress/strain, mechanical/vibration, audio, ATE, laser spectroscopy, biomedical research, LIDAR, geo seismic, dual channel synchronized digitizing, post/pre triggering.
Excellent dynamic accuracy is achieved using a two stage flash conversion process.
The X versus Y display mode coupled with the shift mode function provides a powerful tool for visual comparison of related phenomena.
Sensitivity: +/- 100mV TO +/-50V full scale (200mV p-p TO 100V p-p) 9 steps, 1-2-5 sequence.
Input R & C: 1M OHM +/-2%; 24pF. IEEE standard 488 interface (488-1978).
Interface functions: SH1, AH1, T6, L4, SR1, RL1, PP0, DC1, C0, DT1.
Interface control message: GTL, LLO, SDC-DCL, GET, SPE-SPD, IFC.
All instrument setting and operating modes are programable, except power switch, vertical / horizontal position, horizontal MAG, and external clock switch.
5-digit LED readout display reads voltage difference on the same waveform or between CH 1 and CH 2, absolute voltage. time interval, and 1/T.
