For example, :CHANnel1:VERNier ON /*Turn on the fine adjustment function of CH1 vertical scale*/ :CHANnel1:VERNier? /*The query returns 1*/ :CURSor Command Subsystem :CURSor command is used to measure the X-axis value (such as time) and Y-axis value (such as voltage) of the screen waveform. :CURSor:MODE For example, :CURSor:MODE MANual /*Select manual cursor measurement mode*/ :CURSor:MODE? /*The query returns MAN*/ :CURSor:MANual :CURSor:MANual: TYPE 23 / 136 Description The trim setting is off by default. At this time, you can only set the vertical scale in 1-2-5 steps, that is, 500u, 1mV, 2mV, 5mV, 10mV ... 10V (probe ratio is 1X).
When the trim setting is on, you can further adjust the vertical scale within a smaller range to improve vertical resolution. If the amplitude of the input waveform is slightly larger than the full scale in the current scale, and the amplitude displayed by the waveform of the next gear is slightly lower, you can use fine adjustment to improve the waveform display amplitude to facilitate observation of signal details. Return format The query returns 1 or 0. Command format :CURSor:MODE :CURSor:MODE? Function description Set or query the cursor measurement mode. Parameter Name Type Range Default Discrete {OFF|MANual|TRACk } OFF Description OFF: Turn off the cursor measurement function. MANual:
Turn on the manual cursor measurement mode. TRACk: Turn on the cursor tracking measurement mode. Return format The query returns OFF, MAN, TRAC, AUTO, or XY. Command format :CURSor:MANual:TYPE :CURSor:MANual:TYPE? Function description Set or query the cursor type for manual cursor measurement. Parameter Name Type Range Default Discrete {X|Y } X Description ▷ X: Select X type cursor. The X-shaped cursor is a vertical solid line (Cursor A) and a vertical dotted line (Cursor B). It is usually used to measure time parameters. ▷ Y: Select the Y cursor. The Y cursor is a horizontal solid line (Cursor A) and a horizontal dotted line (Cursor B). It is usually used to measure voltage
