Tektronix 336 en Webster, Massachusetts, USA

The Tektronix 336 is a combination non-storage and digital storage, portable oscilloscope. Tektronix 336 has the capability of displaying analog and digital waveforms simultaneously. Tektronix 336 can store up to 16 digitized waveforms including RECALL and DISPLAY. The 336 is controlled by microprocessor. Most of the features and modes are chosen from a menu on the CRT. The dual channel, DC to 50 MHz Tektronix 663 possesses vertical deflection system for both nonstorage and equivalent time digitizing. It is not possible to digitize the NON STORE X-Y display but the STORE and VIEW digitized waveforms have a menu selectable X-Y display mode. To enable the STORE mode, the horizontal mode must be set to either A only or B delayed. The ROLL Mode is automatically set when the SEC/DIV switch is set to 0.5s per division or slower. The digital storage acquisition modes are NORMAL, ENVELOPE and AVERAGE.
