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 solid retentions like many other Tek handles, it is friction-based instead through rubber washers clamped by the handle. When using the handle to hold the scope at an angle there is only one relatively stable position where the handlebar rests flat on the supporting surface. But even then it shouldn't be carelessly nudged...
There is a removable accessory pouch screwed to 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.
