Through an internal jumper, the front-panel variable control (red knob) can be selected to vary either the main sweep, the delayed sweep or the main sweep hold-off. | Through an internal jumper, the front-panel variable control (red knob) can be selected to vary either the main sweep, | ||

The 7B53 supports X-Y mode by selecting the "Ampl" position on the Time/Div switch. | The 7B53 supports X-Y mode by selecting the "Ampl" position on the Time/Div switch. | ||
The X signal can be picked up from a vertical plug-in via the internal trigger path or applied via the "Main Trig In or Amp In" input, | |||
as determined by the Trigger Source switch setting. Sensitivity on the external input is 100 mV/Div, | |||
which can be increased to 10 mV/DIv by selecting the x10 magnifier, or decreased to 1 V/Div by pushing the EXT÷10 button. | |||

When the delayed timebase trigger source switch is set to INT (pushed in) and the internal connector P613 is in the active position, the DLY'D TRIG IN connector becomes a Delayed Sweep Gate output. This is useful e.g. to connect to a [[7D15]]'s arming inputs, or a [[7D12]]/[[M2]]'s external trigger input. | When the delayed timebase trigger source switch is set to INT (pushed in) and the internal connector P613 is in the active position, | ||
