The Type 1A1 plug-in has two channels and a -3dB point of 50MHz. Early production used a Nuvistor front-end, while later units have FETs. The 1A1 uses the "ALT SWEEP SLAVE PULSE" signal the is sent by scopes on pin 7 of the plug-in connector. This signal allows channel 1 to be displayed using the "A" timebase and channel 2 is to be displayed using the "B" timebase. This is useful, for example, to view the IF and AF of a radio receiver at the same time.
