QM1004A-2-18 Combined RF Upconverter/Downconverter

User Manual

4. POWEr Subsystem Command Reference

4.1 POWEr:CH1ATTEN <numeric value>

This command allows the user to set the attenuation level of the QM1004A-2-18 upconverter to a speci-
fied numeric value. The range of acceptable attenuation values is 0 - 31 dB in 1 dB steps.

Syntax

:

POWE

:

CH1ATTEN

Space

Numeric Value

?

Example

:POWE:CH1ATTEN 31

This command sets the upconverter attenuation to 31 dB

Default Condition

On power up, or when a

*RST

command is issued, the QM1004A-2-18 upconverter attenuation level

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

Query

:POWE:CH1ATTEN?

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 124.5, error

-222, "Data out of range"

occurs.
