The Sony/Tektronix 336 is a 50 MHz dual-trace dual-timebase portable digital storage scope with a full-bandwith analog mode. It represents the highest end model of the 300 series of portable scopes.

The carrying handle doesn't have fixed detents like many other Tek handles. Instead, it is friction-based. The friction between handle and case may be adjusted by screws hidden underneath the plastic side caps. With correctly adjusted friction, the handle can be rotated and will stay in any position, allowing positioning the 'scope at a convenient angle.

A removable accessory pouch is screwed onto the top for probes and cables.

GPIB is an option (01) and brings extra waveform memory as well. Standard and extended memory are volatile and (presumably) capacitor or battery backed SRAM ("Data retention: At least 3 days after 8 hours of operation").

Waveform acquisition is frame-based. Additional memory allows to store more frames, but not longer waveforms. The digitizer works at 1 MS/s with approx 140 kHz of real-time bandwidth. Equivalent time sampling is supported, extending digital storage bandwidth to 50 MHz. Analog bandwidth is always 50 MHz.

X-Y mode with 1 MHz bandwidth. Phase difference is less than 3° to 50 kHz.

The 336A successor has an increased sampling rate of 20 MS/s, autosetup for time and voltage (i.e. horizontal and vertical), more memory and 8 setup storage locations. It was offered at the same catalog price as the 336.
