Sets or queries the vertical displacement of the specified channel. The default unit is V.
Parameters
:<offset> ::= Vertical offset value in NR3 format
:<suffix> ::= {V | mV}
:<n>::= {1 | 2 | 3 | 4}
State
?The set vertical displacement value is affected by the vertical gear and probe ratio.
?The range of legal values varies with the vertical scale and probe ratio. If 21 / 136 you set an offset outside the legal range, the offset value will be automatically set to the closest legal value.
Return
The query returns the vertical displacement value in scientific notation.
Example
:CHANnel1:OFFSet 1V /*Set the vertical offset of CH1 to 1V*/
:CHANnel1:OFFSet? /*The query returns 1*/
1.6 CHANnel<n>:SCALe
Command
:CHANnel<n>:SCALe <scale> [<suffix>]
:CHANnel<n>:SCALe?
Description
Sets or queries the vertical scale of the specified channel. The default unit is V.
Parameters
:<scale> ::=vertical units per division in NR3 format
:<suffix> ::= {V | mV}
:<n>::= {1 | 2 | 3 | 4}
State
?CHANnel<n>:SCALe command to setup each channel’s vertical scale.The settable range of the vertical scale is related to the currently set probe ratio (set by the:
?CHANnel : PROBe command).
Return
The query returns the vertical scale value in scientific notation.
Example
:CHANnel1:SCALe 1V /*Set the vertical scale to 1V*/
Set or query the probe factor of the specified channel.
Parameters
:<atten> ::= {1 | 10 | 100 | 1000}
:<n>::= {1 | 2 | 3 | 4}
State
?Set the probe factor, 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
The query returns the probe attenuation ratio in scientific notation.
Example
:CHANnel1: PROBe 10 /*Set the probe attenuation ratio to 10X*/
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.
Parameters
:<bool> ::= {{1 | ON} | {0 | OFF}}
:<n>::= {1 | 2 | 3 | 4}
State
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
The query returns 1 or 0.
Example
:CHANnel1:VERNier ON /*Turn on the fine adjustment function of CH1 vertical scale*/
Set or query horizontal position of the zoomed view of the main scan[size=10.5000pt].
Parameters
:<pos value> ::= The value of the horizontal position (in seconds)
State
The main scan range and the horizontal position of the main scan determine the range of this command. The value of this command must keep the zoomed view window within the main scan range.
Return
Returns the position of the current horizontal window in the zoomed view in scientific notation.
Example
:TIMebase:WINDow: POSition 0.001 /*Set the horizontal position to 0.001s*/
