Template:Plugin Sidebar 2 The Tektronix 7A26 is a 200 MHz dual-trace vertical plug-in for 7000-series scopes. It was the most successful 7000 series plug-ins, with over 120,000 units produced.

The 75 MHz 7A18 and 400 MHz 7A24 share the same front panel layout and operation.

Key Specifications

Bandwidth	200 MHz
Input impedance	1 MΩ
Deflection factor	5 mV/Div – 5 V/Div in 1–2–5 sequence
Features	Bandwidth limiting switch (20 MHz)

Internals

Controls layout and internal construction is very similar to the 75 MHz 7A18. Whereas the 7A18 is a discrete design, the 7A26 uses Tek-made differential amplifier ICs 155-0078-xx.

The 7A26 does not use the ±50 V supplies provided by the mainframe.
