Type 1A1 has an External Trigger output for mainframes prior to the [[547]] that don't support plug-in triggering, and supplies the trigger system on [[500 Series plug-in interface|pins 4/5 of the mainframe interface]]. It also has a ×10 amplified output from channel 1 that can be cascaded into the channel 2 input for 500 μV/Div sensitivity at reduced bandwidth (15 MHz). | Type 1A1 has an External Trigger output for mainframes prior to the [[547]] that don't support plug-in triggering, and supplies the trigger system on [[500 Series plug-in interface|pins 4/5 of the mainframe interface]].
