Input/Output

Sets the input impedance for voltage-to-power conversions. The
Input Z Corr 50Ω
impedance you select is for computational purposes only, since the
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). Select the
computational input impedance by pressing
useful when measuring a 75 Ω device on an analyzer having a 50 Ω
input impedance, and when using a 75 Ω to 50 Ω adapter on the
analyzer input.
Agilent E4402B with Option UKB, E4404B and E4405B only.
Coupling AC DC
Specifies alternating current (AC) or direct 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. Amplitude
specifications apply only when coupling is set to DC.
When DC coupling is selected, ensure there is no DC component to the
CAUTION
input signal before applying the signal to the analyzer input. The
analyzer's input circuitry can be damaged if DC is applied to the
analyzer input and DC coupling is selected.
Agilent E4401B and E4411B only. Turns the internal amplitude
Amptd Ref
(f=50 MHz) reference signal on or off. When the internal amplitude reference signal
On Off is on, the RF input is disabled.
Agilent E4402B, E4403B, E4404B, E4405B, E4407B and E4408B only.
Amptd Ref Out
(f=50 MHz) Turns the external amplitude reference signal on or off.
On Off
Agilent E4407B with Option AYZ only. Accesses the following Input
