True Dual Channel 30 MHz Sampling Rate (60 MHz in Single Channel Mode) 10-Bit Resolution 2048 Word Memory Per Channel (4096 Single Channel Mode) Cursor-Based Measurements Sample-Rate Switching Direct Plotter Output Capabilty Used for low-to-medium-speed signals, the 390AD Programmable Waveform Digitizer provides crystal-controlled, 30-MHz sampling on two channels. Or, a single channel of data may be digitized at up to 60 megasamples per second. Features include 10 bit vertical resolution, dualchannel synchronized digitizing, pretriggering and posttriggering, sample-rate switching during acquisition, internal cursors for two-point time or voltage measurements and 2048 words of memory per channel. 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. To ensure reliable operation the 390AD includes built-in self calibration and self-test features that are automatically employed at power-on and may be activated during operation by the user.
