Figure 5-6, Signal Channel Menu 1 - Current Input Mode
The Signal Channel Menu 1 has four controls affecting the instrument's signal input
channel, and a key for accessing Signal Channel Menu 2. Changes to the setting of
these controls can be made by using the adjacent keys, with the currently
active selection being shown in highlighted text.
INPUT COUPLING
The input coupling can be set as follows:-
AC
The signal channel is AC coupled at the input with a lower-frequency –3 dB
cut-off of < 0.2 Hz, although it is recommend to use DC coupling at frequencies
< 1.0 Hz for best results. If phase (as opposed to magnitude) readings are
important then DC coupling should be used at higher frequencies, since no
correction is made for amplitude or phase changes caused by the AC coupling
capacitor. Bipolar mode cannot be AC coupled.
DC
The signal channel is DC coupled
