Reference
a. Frequency response values are referenced to the amplitude at 50 MHz
(20 to 30 °C).
b. Settings are: reference level –25 dBm; (75 Ω reference level +28.75 dBmV);
input attenuation 10 dB; center frequency 50 MHz; RBW 1 kHz; VBW 1 kHz;
amplitude scale linear or log; span 2 kHz; frequency scale linear; sweep time
coupled, sample detector, signal at reference level.
c. For reference level 0 to –50 dBm; input attenuation 10 dB; RBW 1 kHz;
VBW 1 kHz; amplitude scale log, log range 0 to –50 dB from reference level;
frequency scale linear; sweep time coupled; signal input 0 to –50 dBm;
span ≤ 20 kHz (20 to 30 °C).
d. 0 to 30 dB for RBW = 200 Hz.
