For example :CHANnel1:SCALe 1 /*Set the vertical scale of CH1 to 1V*/ :CHANnel1:SCALe? /*The query returns 1.000e + 00*/ :CHANnel :PROBe For example, :CHANnel1:PROBe 10 /*Set the probe attenuation ratio of CH1 to 10X*/ :CHANnel1:PROBe? /*The query returns 1.000000e + 01*/ :CHANnel :VERNier 22 / 136 Discrete {1|2|3|4} —— Real type Related to probe ratio Probe ratio is 1X: 500uV to 10V 1V (probe ratio is 10X) Description ▷The settable range of the vertical scale is related to the currently set probe ratio (set by the: CHANnel : PROBe command). ▷You can use the: CHANnel : VERNier command to turn on or off the fine-tuning setting for the vertical scale of the specified channel.
The trim setting is turned off by default. At this time, you can only set the vertical scale in 1-2-5 steps, that is, 500uV, 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 the vertical scale value in scientific notation.
Command format :CHANnel :PROBe :CHANnel :PROBe? Function description Set or query the probe ratio of the specified channel. Parameter Name Type Range Default Discrete {1|2|3|4} —— Discrete {1|10|100|1000} 1 Description ▷Set the probe ratio, which is displayed after multiplying the acquired signal by a specified multiple (does not affect the actual amplitude of the signal). ▷Setting the probe ratio affects the settable range of the current vertical scale. Return format The query returns the probe attenuation ratio in scientific notation. Command format :CHANnel :VERNier :CHANnel :VERNier?
Function description Turn the fine adjustment function of the vertical scale of the specified channel on or off, or query the status of the fine adjustment function of the vertical scale of the specified channel. Parameter Name Type Range Default Discrete {1|2|3|4} —— Bool {{1|ON}|{0|OFF}} 0|OFF
