The Scope Channel Menu; Offset Field - HP 1660CS-Series User Manual

The Scope Channel Menu

The Channel menu selects the channel input and the values that
control the vertical sensitivity, offset, probe attenuation factor, input
impedance, and coupling. The Channel menu also gives you preset
vertical sensitivity, offset, and trigger level values for ECL and TTL
logic levels. Each channel may be set independently of the other
channel.

Offset field

You use the Offset field to set the vertical position of the waveform on the
screen. Offset is the dc voltage that is added to or subtracted from the input
signal so that the waveform can be centered on the waveform display. Offset
range and resolution are dependent on vertical sensitivity (V/Div) as shown
in the table below. The table values are based on a 1:1 probe setting.
Offset Range and Resolution
V/Div Setting
4 mV - 100 mV/Div
>100 mV - 500mV/Div
>500mV - 2.5 V/Div
>2.5 V - 10 V/Div
Offset changes are not reflected on the waveform until a Run is initiated and
the next acquisition is displayed. Changes to Offset during a repetitive run
will be seen on the next displayed acquisition because the hardware is
reprogrammed between acquisitions.
