Mech Atten also appears with no switch, as above, in configurations that include

an Electronic Attenuator but when the Electronic Attenuator is enabled.

Elec Atten

Controls the Electronic Attenuator in Dual-Attenuator configurations. Does not

appear in Single-Attenuator configurations, because the control of both the

mechanical and electronic stages of the Single-Attenuator is integrated into the

single Atten control.

This control includes an Enable/Disable toggle switch; it is only possible to enter a

value for the Electronic Attenuator when this switch is in the Enable position.

For more details of the Electronic Attenuator, see "More Information" on page 700

Remote Command

[:SENSe]:POWer[:RF]:EATTenuation?

Example

:POW:EATT 10

:POW:EATT?

Notes Electronic Attenuation’s specification is defined only when Mech Atten is 6dB

Dependencies Only appears in Dual-Attenuator models with an Electronic Attenuator installed and licensed. Does

not appear in models with the Single-Attenuator configuration, because in the Single-Attenuator

configuration there is no “electronic attenuator”; there is only a single integrated attenuator (which

has both a mechanical and electronic stage). However, in the Single-Attenuator configuration, EATT

SCPI commands are accepted for compatibility with other X-series instruments, and set a “soft”

attenuation. The “soft” attenuation is treated as an addition to the “main” attenuation value set by the

Attenuation control or :POW:ATT, and affects the total attenuation displayed on the Attenuation

control and the Meas Bar

The electronic attenuator, and the “soft” attenuation function provided in Single-Attenuator config-

urations, are unavailable above the low band (0-3.6GHz, 0-3.4GHz, 0-3GHz, depending on the

model). If the low band range is from 0-3.6GHz, and Stop Frequency of the instrument is > 3.6GHz,

then the Enabled/Disabled section of the Elec Atten control will be OFF and grayed-out

If "Internal Preamp" on page 1657 is ON (that is, set to Low Band or Full), the electronic attenuator

(and the “soft” attenuation function provided in Single-Attenuator configurations) is unavailable. In this

case the Enabled/Disabled section of the Elec Atten control will be OFF and grayed-out

If either of the above is true, and the SCPI command is sent, an error indicating that the electronic

attenuator is unavailable is returned

If both the above are true, pressing the control generates error message -221, in other words, the
