3.3 Channel Power Measurement

[:SENSe]:POWer[:RF]:ATTenuation:STEP[:INCRement]?

Example

:POW:ATT:STEP 2

:POW:ATT:STEP?

Notes Has a toggle control on the front panel, but takes a specific value (in dB) when used remotely. The only

valid values are 2 and 10

Dependencies Blanked in EXA, CXA and CXA-m if option FSA (2dB steps) is not present. If blanked, attempts to set it

via SCPI yield an error

Couplings When the attenuation step size changes, the current mechanical attenuation value is adjusted (if

necessary) to be quantized to the new step size. That is, if step is set to 10dB, mech atten is increased

if necessary so it is a multiple of 10dB

Preset EXA, CXA and CXA-m: 10dB (2dB with option FSA)

All other models: 2dB

Max Mixer Level

Allows you to set the maximum level to be applied to the mixer for a signal at the top

of the screen. By setting this value up or down you can allow more or less signal

through the system.

The major impact of changes to Max Mixer Level is seen in changes to the value to

which Reference Level is limited. Max Ref Level depends on Max Mixer Level and

Attenuation, and therefore a higher Max Mixer Level may let you set Ref Level

higher. However, changing this value can impact your TOI, compression, or dynamic

range. The preset value of this function is best for most measurements.
