3 Short-Range Comms & IoT Mode
3.6 Power Stat CCDF Measurement
frequency range lockout takes precedence
If the electronic/soft Attenuator is enabled, then the Stop Freq of the instrument is limited to 3.6GHz
and Internal Preamp is unavailable
If "LNA" on page 1658 is ON, 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. This coupling works in the following modes/measurements:
–
Channel Power, Occupied BW, ACP, SEM, Spurious Emissions, Power Stat CCDF measurements
in all Modes
–
Transmit On|Off Power measurement in 5GNR Mode
–
Power vs. Time and Transmit Power measurement in GSM/EDGE Mode
–
Burst Power measurement in Spectrum Analyzer Mode
The SCPI-only “soft” electronic attenuation for the single-attenuator configuration is not available in
all measurements; in particular, it is not available in the Swept SA measurement
Couplings Enabling and disabling the Electronic Attenuator affects the setting of the Mechanical Attenuator (in
Dual-Attenuator configurations). This is described in more detail below and in "Mechanical Attenuator
Transition Rules" on page 700
Preset 0dB
State Saved Saved in instrument state
Min 0dB
Max Dual-Attenuator configuration: 24dB
Single-Attenuator configuration: the total of ATT and EATT cannot exceed 50dB. So, if the EATT is set
to 24dB first, the main attenuation cannot be greater than 26dB and will be reduced accordingly; if
the main attenuator is set to 40dB first, EATT cannot be greater than 10dB

Preset OFF (Disabled) for Swept SA measurement
ON (Enabled) for all other measurements that support the electronic attenuator
NOTE
The maximum Center Frequency for Low Band can change based on the
selected IFBW for measurements that support IFBW (for example, Waveform
measurement across all Modes that support it). In certain models (such as
N9042B & N9032B), IFBW values <= 40MHz have a maximum Low Band
frequency of 3.6GHz, while 40MHz < IFBW <= 1GHz have a maximum of
3.3GHz, and 1GHz < IFBW <= 1.5GHz have a maximum of 3.5GHz. This
