Resolution, Isolation Modules)

Function
The offset voltage can be set regardless of the input coupling setting.
Offset voltage setting range
The setting range varies depending on the input module as shown below.
For High-Speed Isolation Module (701855) and High-Speed Module (701856)
Sensitivity Range (Probe=1:1)
Offset Voltage Setting Range
5 mV/div to 50 mV/div
-0.5 V to 0.5 V
100 mV/div to 500 mV/div
-5 V to 5 V
1 V/div to 5 V/div
-50 V to 50 V
10 V/div to 20 V/div
-250 V to 250 V*
The setting resolution is 0.01 div. If the voltage scale is 5 mV/div, for example, the setting resolution will
0.05 mV.
* Do not apply an input exceeding the maximum input voltage.
For High-Resolution, High-Voltage, Isolation/High-Resolution, Isolation Module
• The waveform can be set in the range between
±
4 div.
• The setting resolution is 0.01 div.
Canceling the offset voltage
If the item being controlled by the jog shuttle is “Offset,” pressing the
RESET
key sets the
offset voltage to 0 V.
Points for attention
• The offset voltage is effective even when the acquisition is stopped.
• The offset value does not affect cursor measurements, automatic measurements, or math
computations.
• If you change the probe attenuation, the offset changes proportionally to reflect the new
attenuation rate.
• Changing the voltage sensitivity does usually not affect the offset value. Only if the change
would cause the offset to go out of range, the offset moves to the nearest range limit. If you
then return to the original sensitivity, the offset returns to its original setting as well
(provided that you have not explicitly changed the value in the meantime).
Operating Procedure
Setting the offset voltage
1.
Press one of the keys
CH1
to
CH16
to select the desired channel.
2.
Press the “
V Zoom/Offset
” soft key to set jog shuttle action to “
Offset
.”
3.
Turn the jog shuttle to set the desired offset voltage.
You can change the setting a digit using the arrow keys (located below the jog shuttle).
Canceling the offset voltage (setting it to 0 V)
You can return the offset to 0V by pressing the
RESET
key.
