AMPTD Y Scale
a single attenuator with combined mechanical and electronic sections thatcontrols all the attenuation
functions. Different models in the X-Series come with different configurations.
See “Dual Attenuator Configurations” on page 851.
See “Single Attenuator Configuration:” on page 852
Most Attenuation settings are the same for all measurements – they do not change as you change
measurements. Settings like these are called “Meas Global” and are unaffected by Meas Preset.
Dual Attenuator Configurations
Configuration 1: Mechanical attenuator + optional electronic attenuator
Configuration 2: Mechanical attenuator, no optional electronic attenuator
Key Path: AMPTD Y Scale
Scope: Meas Global
Dependencies: In measurements that support the I/Q inputs, this key is unavailable when I/Q
is the selected input, and is replaced by the Range key in that case.
Attenuator controls and settings are not available on the E6607C. If any
attenuator commands are sent to the E6607C the following error will be
generated: –241;Hardware missing; not available for this model number
Readback Line: Contains a summary in [ ] brackets of the current total attenuation. See the
descriptions of the “(Mech) Atten ” on page 852, “Enable Elec Atten” on
page 854, and “Elec Atten” on page 857 keys for more detail on the
contributors to the total attenuation.
Note that when "Pre-Adjust for Min Clip" is on, this value can change at the
start of every measurement.
