Digital Oscilloscope Series

CHANNEL
ATTENUATION | ATTN
Command /Query
DESCRIPTION
The ATTENUATION command specifies the
probe attenuation factor for the selected channel.
The probe attenuation factor may be 0.1 to
10000.This command does not change the actual
input sensitivity of the oscilloscope. It changes
the reference constants for scaling the display
factors, for making automatic measurements,
and for setting trigger levels.
The ATTENUATION? query returns the current
probe attenuation factor for the selected channel.
COMMAND SYNTAX
<channel>:ATTENUATION <attenuation>
<channel>:={C1,C2,C3,C4}
<attenuation>:={0.1,0.2,0.5,1,2,5,10,20,50,100,2
00,500,1000,2000,5000,10000}
QUERY SYNTAX
<channel>:ATTENUATION?
RESPONSE FORMAT
<channel>:ATTENUATION <attenuation>
EXAMPLE
The following command sets the attenuation
factor of Channel 1 to 100:1. To ensure the data
matches the true signal voltage values, the
physical probe attenuation must match the scope
attenuation values for that input channel.
Command message:
C1:ATTN 100
