2.1.3.2 Ref Level
Sets the maximum power or voltage to be displayed at the upper left of the display
grid.
Key Points:
 This value is affected by a combination of maximum mixing level, input
attenuation, and preamplifier. When you adjust it, the input attenuation is
adjusted under a constant max mixing level, meeting:

denotes the reference level, the input attenuation,
the preamplifier (For DSA1030/DSA1030-TG), and the max mixing level,
respectively.
 You can modify this parameter using the numeric keys, knob, or direction keys.
For more details, please refer to “Parameter Input”.

Parameter Explanation
Default 0 dBm
Range -100 dBm to 30 dBm
Unit dBm, -dBm, mV, uV
Knob Step in Log scale mode, step = Scale/10
in Lin scale mode, step = 0.1 dB
Direction Key Step in Log scale mode, step = Scale
in Lin scale mode, step = 1 dBm
2.1.3.3 Input Atten
Sets the front attenuator of the RF input in order to permit big signals (or small signals)
to pass from the mixer with low distortion (or low noise).
Key Points:
 When the preamplifier is On, the input attenuation could be set up to 30 dB. You
can adjust the reference level to ensure that the specified parameters meet the
