:CHANnel<n>:PROBe 
 
Syntax 
:CHANnel<n>:PROBe <atten> 
:CHANnel<n>:PROBe? 
 
Description 
Set or query the probe attenuation ratio of the specified analog channel. 
 
Parameter 
Name  Type  Range  Default 
<n>  Discrete  {1|2}  -- 
<atten>  Discrete 
{0.01|0.02|0.05|0.1|0.2|0.5|1|2|5|10|20 
|50|100|200|500|1000} 
1 
 
Explanation 
  After setting the probe ratio, multiply the sampled signal by the specified multiple and then display 
the result (the actual amplitude of the signal will not be affected).   
  Setting the probe ratio affects the range of the vertical scale.  
 
Return Format 
The query returns the attenuation ratio currently set. 
 
 
:CHANnel<n>:UNITs 
 
Syntax 
:CHANnel<n>:UNITs <units> 
:CHANnel<n>:UNITs? 
 
Description 
Set or query the amplitude display unit of the specified analog channel. 
 
Parameter 
Name  Type  Range  Default 
<n>  Discrete  {1|2}  -- 
<units>  Discrete  {VOLTage|WATT|AMPere|UNKNown}  VOLTage 
 
Return Format 
The query returns VOLT, WATT, AMP or UNKN.
