Notes The TEKTRONIX 7912AD Programmable Digitizer is a wide-bandwidth waveform acquisition instrument with both analog and digital outputs. Programming is accomplished over the bus specified in IEEE Standard 488.
Two operating modes are provided. In the digital mode, the 7912AD digitizes either a single-shot or repetitive waveform and stores it for internal processing or for output on the IEEE 488 bus. Analog outputs are also provided to display the waveform data on an X-Y-Z monitor. In the TV mode, the 7912AD converts a waveform to a composite Video output. This allows the input waveform to be displayed on a TV monitor such as the TEKTRONIX 634 Monitor, one of the 650- and 670-series of color Picture Monitors.
In either the TV or digital mode, the 7912AD can acquire waveforms with high bandwidth: up to 500 MHz with the TEKTRONIX 7A19 Amplifier plug-in, for instance, or 1 GHz with the TEKTRONIX 7A21N Direct Access plug-in. The time window can be selected between 10 milliseconds and 5 nanoseconds using a TEKTRONIX 7000-series time base plug-in. This is equivalent to sampling rates (in digital mode) from 50 kHz to 100 GHz.
Remote control and data output via the IEEE 488 bus simplified by two microprocessor systems in the 7912AD. The firmware operating systems for these microprocessor is designed to let the programmer talk to the 7912AD in as simple and obvious manner as possible.
Design of the firmware that controls the IEEE 488 interface is consistent with the IEEE 488-1975 standard. Extended addresses are used so that the 7912AD can act as a transparent Interface for programmable plug-ins (if installed). These plug-ins include the 7A16P Programmable Amplifier and the 7B90P Programmable Time Base.
The 7912AD operates in many respects like an oscilloscope such as those in the TEKTRONIX 7000-series. The Input signal is connected to a vertical plug-in to drive the vertical deflection amplifier. A number of 7000-series plug-ins are available to tailor the 7912AD for bandwidth, input impedance, differential or single-ended input, and input voltage. On most vertical plug-ins, a wide range of deflection factors (amplification) can be selected on the front Panel. A number of 7000 - series time base plug-ins are available to drive the horizontal deflection amplifier at calibrated sweep rates.
Although the vertical and horizontal deflection systems of the 7912AD are similar to those of an oscilloscope, the similarity ends there. In place of the oscilloscope CRT, there is a scan converter tube. Instead of displaying the input waveform as a trace an the phosphor coated face of a CRT, the input waveform is written an a silicon diode matrix and read from this target as in a vidicon TV camera.
