:CHANnel<n>:SCALe
Syntax :CHANnel<n>:SCALe <scale>
:CHANnel<n>:SCALe?
Description
Set or query the vertical scale of the specified channel. The default unit is V.
Parameter
Name
Type
Range
Default
<n> Discrete {1|2|3|4} --
<scale> Real Related to the current probe ratio.
probe ratio = 1: 1mV to 10V
probe ratio = 10 (default): 10mV to 100V
1V (the probe
ratio is 10)
Explanation  The range of the vertical scale is related to the current probr ratio (set by
the
:CHANnel<n>:PROBe command). As the default probe ratio of DS1000Z is 10,
the default value of <scale> is the value when the probe ratio is 10.
 You can use the
:CHANnel<n>:VERNier command to enable or disable the fine
adjustment of the vertical scale. By default, the fine adjustment is off. At this point,
you can only set the vertical scale in 1-2-5 step, namely 1mV, 2mV, 5mV, 10mV, …,
10V. When the fine adjustment is on, you can further adjust the vertical scale within
a relatively smaller range to improve the vertical resolution. If the amplitude of the
input waveform is a little bit greater than the full scale under the current scale and
the amplitude would be a little bit lower if the next scale is used, fine adjustment can
be used to improve the display amplitude of the waveform to view the signal details.
Return
Format
The query returns the vertical scale in scientific notation.
Example
:CHANnel1:SCALe 1 /*Set the vertical scale of CH1 to 1V*/
:CHANnel1:SCALe? /*The query returns 1.000000e+00*/

Description
Set or query the probe ratio of the specified channel.

Default
<n> Discrete {1|2|3|4} --
<atten> Discrete {0.01|0.02|0.05|0.1|0.2|0.5|1|2|5|10|20|50|1

10
Explanation  Setting the probe ratio refers to multiply the signal sampled with the specified ratio
and then display the result (the actual amplitude of the signal will be not affected).
 Setting the probe ratio will affect the range of the vertical scale.
Return
Format
The query returns the probe ratio in scientific notation.
Example
:CHANnel1:PROBe 10 /*Set the probe ratio to 10*/
:CHANnel1:PROBe? /*The query returns 1.000000e+01*/
