Input/Output
Sets the input impedance for voltage-to-power conversions. The
Input Z Corr
impedance you select is for computational purposes only, since the
50Ω 75Ω
actual impedance is set by internal hardware to 50 Ω (except for
Option 1DP). The default is 50 Ω (75 Ω with Option 1DP). Setting the
computational input impedance to 75 Ω is useful when using a 75 Ω to
50 Ω adapter to measure a 75 Ω device on an analyzer having a 50 Ω
input impedance.

Coupling
and E4404B or E4405B. Specifies alternating current (ac) or direct
AC DC
current (dc) coupling at the analyzer input. Selecting ac coupling blocks
any dc voltage at the analyzer input, but also decreases the frequency
range of the analyzer. Input coupling is set to ac by an instrument
preset (With
apply only when coupling is set to dc. Refer to the appropriate
amplitude specifications and characteristics for your analyzer.
