HP 8711C User Manual page 105

The markers provide numerical readout of trace data. Markers have a
stimulus value (the x-axis value) and a response value (the y-axis value).
When you switch on a marker, and no other function is active, the analyzer
shows the marker stimulus value in the active entry area.
You can control markers with the front panel knob, the step keys, or the front
panel numeric keypad. The markers are activated by pressing the C-1
key. See Figure 4- 1.
