QM1004-2-18 Combined RF Upconverter/Downconverter

User Manual

3. POWEr Subsystem Command Reference

3.1 POWEr:CH1:ATTENuation <numeric value>

Note:

This v6 command replaces the POWE:CH1ATTEN command available in previous hardware ver-

sions. The GUI currently supporting v4, v5, and v6 hardware uses both commands to maintain support,
while v6 hardware only uses this latest command.

This command allows the user to set the RF attenuation level of the QM1004-2-18 upconverter to a spec-
ified numeric value. The range of acceptable attenuation values is 0 - 31 dB in 1 dB steps.

Syntax

POWE

CH1

ATTEN

Space

Numeric Value

Example

:POWE:CH1:ATTEN 31

This command sets the upconverter attenuation to 31 dB

Default Condition

On power up, or when a

*RST

command is issued, the QM1004-2-18 upconverter attenuation level returns

to the boot state’s setting. The Combined RF Upconverter/Downconverter default setting is 0.

Query

:POWE:CH1:ATTEN?

This query returns the current upconverter attenuation level

Error Message

If the parameter is not in the recognized format, error

-102, "Syntax error"

occurs.

If the parameter is less than 0 or greater than 31.5, error

-222, "Data out of range"

occurs.
