326
The Sony/Tektronix 326 is an ultra-portable 10 MHz dual trace oscilloscope with 300 ns delay line and a removable battery pack.
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.
The power supply and oscilloscope are separable. The scope can be be operated without power supply.
