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. | |||
