6 Input/Output
6.9 Calibration
The attenuation set by this control cannot be decreased below 6dB with the knob or step keys. To get
to a value below 6dB it must be directly entered from the keypad or via SCPI. This protects from
adjusting the attenuation to a dangerously small value, which can put the instrument at risk of damage
to input circuitry. However, if the current mechanical attenuation is below 6dB it can be increased
with the knob and step keys, but not decreased
Max CXA Option 503 or 507: 50 dB
EXA: 60dB
All other models: 70dB
Note that, in the single attenuator configuration, the total of ATT and EATT cannot exceed 50 dB, so if
the EATT is set to 24 dB first, the main attenuation cannot be greater than 26 dB and is reduced
accordingly; if the main attenuator is set to 40 dB first, EATT cannot be greater than 10 dB
6.9.1.33 Mech Atten Stop
Determines the last Mechanical Attenuator to be used in the Calibration
Remote Command
:SYSTem:CALibration:ROW[1]|2|…|100:ATTenuation:STOP <rel_ampl>
:SYSTem:CALibration:ROW[1]|2|…|100:ATTenuation:STOP?
Example
:SYST:CAL:ROW3:ATT:STOP 30
Dependencies Disabled unless "Mech Atten Type" on page 2499 is STEP
The SCPI command applies to the currently selected Cal Group
If the subopcode does not reference an existing Cal row in the Cal Group, the error message “-
221,Settings conflict; Subopcode does not reference an existing Cal row” is generated
Couplings Coupled to "Mech Atten Start" on page 2499. Mech Atten Start must be <= Mech Atten Stop. If Mech
Atten Start > Mech Atten Stop, then Mech Atten Stop = Mech Atten Start
Preset 10dB
