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

The power supply and oscilloscope are separable. The scope can be be operated without power supply.

Electrically, it is relatively classic, but it is not constructed like classic Tek scopes.

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.
