Relative Phase DSA2

ΦDSA2RELMAX DSA set to 29dB, relative to 0dB attenuation state.

ΦDSA2RELMID DSA set to 14dB, relative to 0dB attenuation state.

[a] Specifications in the minimum/maximum columns that are shown in bold italics are guaranteed by test. Specifications in these columns that are

not shown in bold italics are guaranteed by design characterization.

[b] 1dB compression point is a linearity figure of merit. Refer to Abs Max Ratings table for maximum RF input power.

[c] Signal applied to RFIN_A (RFIN_B) and measure desired signal at RFOUT_B (RFOUT_A) and compare to signal level at RFOUT_A

(RFOUT_B).

[d] Channel A or Channel B DSA combinations which yield 24dB in total attenuation. DSA2_A or DSA2_B settings limited to the following: 0dB,

6dB, 12dB, 18dB, and 24dB.

[e] Channel A or Channel B DSA combinations yielding 35dB in total attenuation. DSA2_A or DSA2_B settings limited to the following: 5dB, 11dB,

17dB, 23dB, and 29dB. Since the maximum attenuation state totals 59dB, this will yield a 24dB difference between the two channels.

[f] The attenuators can be assumed to be purely resistive elements when performing cascaded analysis calculations. Be sure to take into account

any relevant INL/DNL effects.
