The '''Sony/Tektronix 326''' is an ultra-portable 10 MHz dual trace oscilloscope with a 300 ns delay line and a removable battery pack.


electrical ist very classic, but it´s not a classic tek.
The power supply and oscilloscope are separable.
326 has no Custom IC, but many transistor from sony.
The scope can be be operated without power supply.
His powersupply/charger is similar to 323, but 0,33ohms Resistor is in accu-pack.


[[list of manuals that are needed|Manual needed]].
Electrically, it is relatively classic, but it is not constructed like classic Tek scopes.


* [http://w140.com/tek_326_desc.pdf Tektronix 326 Specifications (PDF)]
The 326 has no Tek-made ICs. It uses many Sony transistors.


The 326's power supply/charger is conceptually similar to that of the [[323]],
but the 0.3 Ω resistor is in the battery pack.
