Attenuation
Attenuation

10 Hz to 128 MHz
Cumulative and Incremental
Attenuation
To determine the attenuation
specification between any two
[3]
output levels, apply an RSS
summation of the dB values
listed for each output level.
[1] 50 Ω Output attenuation specifications are typical at absolute levels of less than -48 dBm up to 20 kHz, at less than -74 dBm up to
100 kHz, and at less than -84 dBm at all frequencies.
[2] 75 Ω Output attenuation specifications are typical at absolute levels of less than -54 dBm up to 20 kHz, at less than -80 dBm up to
100 kHz, and at less than -90 dBm at all frequencies.
