Part 6: IEEE 488.2 Command Reference
ATTENUATION, ATTN
Description
The ATTENUATION command selects the vertical attenuation factor of the probe. Values up to 10000
can be specified.
The ATTENUATION? query returns the attenuation factor of the specified channel.
Command Syntax
<channel>:ATTENUATION <attenuation>
<channel>:= <C1 to Cn, EX, EX10>
<attenuation>:= {1, 2, 5, 10, 20, 25, 50, 100, 200, 500, 1000, 10000}
Query Syntax
<channel>:ATTENUATION?
Response Format
<channel>:ATTENUATION <attenuation>
Example (GPIB)
The following instruction sets the attenuation factor of C1to 100:
CMD$="C1:ATTN 100": CALL IBWRT(SCOPE%,CMD$)
6-17
