5.2.10 Scale Fidelity
5-35
5.2.10 Scale Fidelity
The 10 dB/div, 1 dB/div and linear scales are tested for fidelity. The 1 dB/div scale is tested in RBW setting
of 1 MHz. The 10 dB/div scale and the Linear scale are tested in RBW setting 3 kHz. A signal is set to the
reference level for each scale. As the signal amplitude is decreased using 1 dB step attenuator and 10 dB
step attenuator, the displayed signal amplitude is compared to the reference level.
Specification:
Log Scale Fidelity: ±0.2 dB/1 dB
±1.0 dB/10 dB
±1.5 dB/90 dB
Linear Scale Fidelity: ±5% of reference level
