1.6 CHANnel<n>:SCALe
1.7 CHANnel<n>:PROBe
1.8 CHANnel<n>:VERNier
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*/
:CHANnel1:SCALe?/*The query returns 1.000e + 00*/
Command
:CHANnel<n>:PROBe <atten>
:CHANnel<n>:PROBe?
Description
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*/
:CHANnel1:PROBe? /*The query returns 1.000000e + 01*/
Command
:CHANnel<n>:VERNier <bool>
:CHANnel<n>:VERNier?
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.
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
